Kazuya Shiina reincarnates as Cain von Silford. During his baptism, he meets seven gods—Zenom, Rime, Reno, Sarnos, Grim, Panam, and Bela—who grant him their protection and magical abilities, all at level 10, which is beyond the usual level 1-5. Cain hides his levels but shows the number of protections and magic to his family, leading his father to order his family to stay silent about his powers to avoid political turmoil.

Episode 1

TL;DR

Recap

On his way to a convenience store, Kazuya Shiina attempted to defend two young girls from an armed assailant, only to end up getting stabbed himself and dying on the spot. He reincarnates as three-year-old Cain von Silford, the third son of Garm, the margrave of Gracia—a region within the Kingdom of Esfort—and his second wife, Sarah. Cain also has a sister, Reine, who is two years older than him, as well as two older half-brothers, Djinn and Alec, from Garm’s first wife, Maria.
As Cain grows, he learns about the Forest of Monsters located just south of Gracia, the existence of adventurers, and the concept of magic in this new world. His family is astounded by how quickly Cain picks up math and writing. Since Cain will not inherit the family estate, his father is supportive of his learning and allows him to study as much as he wants, including delving into books about magic. However, Caine is told that he will likely need to wait until his baptism at age five to officially use magic. Nevertheless, through his studies, he secretly learns how to use magic.

Reine, noticing Cain’s fascination with the outside world, educates him about the 300-year history of the Kingdom of Esfort. She shares details about how the first king of the kingdom began as an adventurer before founding the nation. Cain speculates that the first king was likely Japanese, noting the name Yuuya, as well as learns about the presence of elves, dwarfs, and beastfolk in this world.
Two years later, Cain and his family journey to the church for his baptism. During this trip, Cain learns about status magic and is surprised by Reine’s ability to wield three different types of magic. His mother explains that Reine was granted level 2 protection by the God of Magic, and he learns that magic and protection can exist on levels 1 through 5. These levels determine a user's natural talent, with higher levels offering greater magical ability, while protection determines how much energy is required to activate spells and influences other skills.

The Kingdom of Esfort follows the Marineford faith, which venerates seven pillar gods. During his baptism, a bright light envelops Cain, and he finds himself at a table with the seven gods. Zenom, the God of Creation and the creator of the world, introduces himself. Rime, the god of death and the cycle of rebirth, explains that Kazuya’s death was unplanned, as the assailant would have likely tripped and the two girls would have survived on their own. However, due to Kazuya’s selfless act of heroism, the God of Earth requested that Rime grant Kazuya a new life in this world.

All seven gods—Zenom, Rime, Reno (the God of Magic), Sarnos (the God of War), Grim (the God of Technology), Panam (the God of Commerce), and Bela (the God of Earth)—offer their protection to Cain. Upon returning, Cain secretly examines his status and discovers that all seven gods have given him their protections, each at incredible level 10 stats. Zenom grants Cain the ability to create magic, so Cain uses status conceal to hide his stats from others.

During a family dinner, Cain reveals his stats to his family, shocking them with his seven protections and his unconcealed magic of 344,560, which is substantially greater than the average of 10,000 for palace mages. Worried that Cain will be seen as a threat to the country, his father Garm, instructs the servants Sylvia and Sebas and the rest of the family to keep this information quiet during his debut party. At night, Cain attempts to summon a fluffy animal but accidentally summons a giant beast instead. To protect Reine and Parma, he cancels the summoning.

At his debut party, Cain boldly announces his desire to become an adventurer. The after-credits scene reveals a conversation between Rime and Zenom. Rime questions whether it was wise to give Cain protections higher than level 5, but Zenom reassures her, explaining that Cain must not only become the strongest in the kingdom but also the strongest on the entire continent by the age of sixteen, as a time will come when his strength will be essential.

Episode 2

TL;DR

Recap

Garm arranges tutors for Cain to support his studies, hiring D-rank adventurers Millie and elf Nina to teach him for three years. On his first day of training, they are astonished by five-year-old Cain's swordsmanship, prompting Millie to engage in a mock battle with him. During the fight, they learn that Cain has protection from the God of War. Unable to keep up with his pace, Millie transitions the lesson to Nina, who begins teaching Cain magic. Though Nina has level 3 protection from the God of Magic and planned to start with the basics, Cain quickly demonstrates that he has already mastered the fundamentals through self-study. His ability to use unchanted magic and all elemental types at such a young age amazes Nina, who declares Cain a genius, noting that even palace mages of the sage class cannot use all elements.

Cain further surprises his tutors by pulling a towel from his Item Box, a skill that only those with protection from the god of commerce can use. This prompts Millie and Nina to wonder how many divine protections Cain possesses. They discuss his progress with his parents and explain that practicing intermediate-level magic on the estate grounds could damage the mansion. Garm grants Cain permission to practice outside of the estate, with strict instructions to return by sundown and know his limits. Cain then tries intermediate magic on a boulder and obliterates it with power far beyond the intermediate level. When a Killer Rabbit appears from the bushes, Cain swiftly kills it with Air Bullet, earning praise for his first kill. Cain decides to store the rabbit in his Item Box to show his family. Mesmerized by the Item Box once again, Millie and Nina mention their plans to save up for a Magic Bag, an expensive alternative for those without the Item Box skill.

Using Search, Nina identifies more monsters nearby, and Cain surprises her by using the ability himself on his first try, accurately locating four Killer Rabbits. As part of their training, they defeat the rabbits, but when one flees toward the forest, Millie and Nina stop Cain from following. They explain the forest's dangers, including strong monsters that attack the city once every few decades. Cain realizes this is why the city wall is so fortified. Back home, Cain checks his stats and discovers he has leveled up to level 8. Reviewing his skills, he finds "God's Chosen," which grants him 100x experience and ability growth rates.
On another day, the group visits the adventurers' guild, where Cain meets Rudy, the dog beastfolk receptionist. While discussing potential missions, they are interrupted by C-rank adventurer Crosse and his crew, who mock Millie and Nina for being D-rank. When Crosse gets aggressive, Cain intervenes, defeating him effortlessly and stopping his sword with a single finger. After kicking Crosse and his crew out, Millie and Nina thank Cain, vowing to protect him in the future.

Later, as the end of their time together comes near, Cain learns that his tutors have declined to extend their contracts. As a farewell gift, Cain ventures into the forest to create Magic Bags for them. He defeats a Blood Ogre to make a red bag for Millie and an Earth Dragon for a green bag for Nina. These battles cause explosions, alarming the wall guards, who suspect a monster outbreak. Garm leads troops into the forest but finds only craters and Cain’s handkerchief.

On their final training day, Millie and Nina witness eight-year-old Cain single-handedly defeat a pack of wolves. They congratulate him on his "graduation," and Cain presents them with the Magic Bags he crafted. The tutors are shocked to learn the bags are made from monsters that even A-rank adventurers struggle to defeat and have a capacity large enough to store his family’s mansion. Milli and Nina remark that these bags are national-treasure class items and worry that holding them could lead them to becoming targeted. However, Cain assures them the bags are secure, as they become unbearably heavy for anyone else, leading the two to declare the bags to be even beyond national-treasure class before accepting them.

In the post-credits scene, Garm nags at Cain for recklessly fighting the Blood Ogre and Earth Dragon when he is only eight years old.

Recap

After defeating a dragon and earning the aliases “Enemy of All Monsters” and “Dragon Killer,” Cain, now ten years old, travels to the royal capital for his noble debut. On the journey, his sister Reine expresses excitement about their future in the capital, though Garm reminds them Cain must wait two years to start school. Along the way, Cain uses Search as a safety measure and detects a monster attack on a group of soldiers protecting a carriage. Ignoring his father's warnings, he goes ahead alone, defeats the monsters using advanced magic, heals the injured, and stores the fallen soldiers in his Item Box. The carriage reveals Princess Telestia and Duke Santana’s daughter, Silk, who thank Cain for saving them and invite him to travel with them. Upon reaching Renoma, Telestia and Silk, who are both smitten with Cain, insist on sharing a room with Cain, citing safety concerns. Despite Garm’s objections, they end up sleeping in adjacent beds, leaving Cain sleepless for several nights.

At the royal palace, Cain is thanked by the vice-captain of the Royal Chivalric Order for protecting the girls and bringing the fallen soldiers home. During his audience with the king, Cain’s actions are recounted, astonishing the nobles. The king rewards Cain with the title of baron, ten platinum coins, and a mansion, ignoring objections from other nobles. Later, the king proposes that Cain becomes engaged to Telestia and Silk, citing their shared travels and the potential scandal of their close interactions. Though hesitant, Cain reluctantly agrees under pressure from the king and Duke Santana. In a flashback, it is revealed the decision was also influenced by the girls’ affection for Cain and the kingdom’s desire to keep him close due to his exceptional abilities. In the after-credits scene, Reine and Garm interrogate Cain about his newfound engagements, teasing him about his “philandering.”

TL;DR

Recap

Cain visits the church to consult with the gods about his extraordinary stats. Zenom acknowledges that Cain’s abilities are inhuman, jokingly offering him the status of a demigod—placing him in the same category as holy beasts and divine dragons. However, Zenom warns Cain not to push the limits of his power and advises him to seek help when needed. Additionally, Zenom requests Cain to use his knowledge from his previous life to create new entertainment for the world, as it lacks such diversions. Cain agrees, excited to introduce his ideas.

Later, while shopping for dresses with Reine, Cain feels uncomfortable in the boutique and steps outside. There, he encounters Parma, who is training at her uncle Tamanis’s shop. Cain meets Tamanis and explores the shop, then proposes an idea for a board game he calls "Reversi." Tamanis agrees to produce the game, and Cain provides a gold coin as an investment, surprising Tamanis with its value. Cain requests prototypes and funds the venture generously. To secure exclusivity, Cain and Tamanis draw up a contract blessed by the God of Commerce, ensuring that no one else can produce the game for three years. After finalizing the contract, the prototype disappears, sent to the gods for their enjoyment. Cain plans for mass production, including a version for the royal household, which Tamanis hesitates to create until Cain encourages him.

Returning home, Cain faces an angry Reine, upset that he forgot about her while she tried on dresses. To make amends, she models all her outfits for him at home, which Cain continuously praises. Just as it’s Cain’s turn to try on clothes, Sylvia interrupts to inform him that Tamanis has requested his presence again. At the shop, Cain finds the completed Reversi prototype and demonstrates the game to Tamanis and Parma, who are thrilled by its potential. Cain commissions 1,000 affordable versions and 50 luxury versions for nobles, providing additional funds to overcome production limitations.

As the debut ceremony approaches, Garm warns Cain to be cautious of parents introducing their daughters for marriage, given his baron title. At the ceremony, Cain encounters Duke Santana and Silk, who thank him again for saving Silk’s life. Cain compliments Silk’s dress, prompting the duke and Garm to note his mature speech. Cain later meets Telestia, whom he calls an angel, much to her father’s disapproval. He gifts a Reversi set to the royal family, surprising them with its novelty.

During the event, Silk approaches Cain, and they drop formalities, addressing each other casually. Soon after, Corgino’s son, Habit, and his lackeys approach, demanding Cain treat them with deference, assuming he’s the son of a baron. Cain refuses to apologize, and they challenge him to a duel outside. Habit’s lackeys cast weak spells with grand theatrics, amusing Cain. Silk interrupts, revealing Cain’s true rank as a baron, shocking the group and prompting their hasty apologies. Silk teases Cain about his cunning side, suggesting a date to keep her silence. Telestia overhears and demands a date as well, pouting when Cain agrees.

At that moment, the king overhears their conversation. Protective of Telestia, he declares that he must discuss Cain’s creation of the game and his relationship with his daughter, ensuring Cain’s attention is firmly fixed on the matters at hand.

Cain receives the key to his mansion but finds it run-down and uses magic to restore it. Sylvia, three maids, and his new butler Colan arrive to help organize the mansion. Cain returns to his family estate to meet his half-brothers, who are impressed by his peerage and tease Reine. When the family visits the mansion, they are surprised by its transformation and shocked to find a mounted red dragon, which Cain explains he defeated. Garm praises its value, while Sarah and Reine marvel at Cain’s magical toilet. Garm informs Cain he must host a debut party for the mansion. Despite initial stress, Cain plans unique gifts, including glassware and sparkling wine, which impress his guests. At the party, the king, who insists on attending, praises Cain's hospitality, as does the queen, who requests the magical toilet for the palace.

Marquis Corgino arrives late, acting rudely and disparaging Cain’s efforts, until Cain cunningly introduces him to "the kingdom’s biggest"—the king himself. The king reprimands Corgino for his behavior, leaving him humiliated. Silk teases Cain for orchestrating the situation, while Eric and the king humorously confront him about his tactics. Later, Cain apologizes but secretly enjoys his clever handling of Corgino, earning him a light-hearted two-hour lecture from the king.

Recap

Cain meets Vice Captain Daim to store his monster materials, but the room Daim offers is too small. Cain shocks Daim by revealing a mountain of A-rank monster materials, including an earth dragon, a feat that would challenge an entire A-rank party. Daim wonders if Cain is a hero or a disciple of the gods, but Cain insists he is just a normal boy. While the knights appraise the materials, Daim introduces Cain to the Royal Chivalric Order and suggests a mock battle while they wait for the captain. Initially underestimated due to his appearance, Cain swiftly defeats a knight using Boost. When Daim asks Cain to face all the knights at once, the captain, Tifana von Liebert, intervenes and challenges him herself. Cain narrowly wins the duel using Clock Up, and Tifana, impressed, declares she will marry him. Cain protests, citing his age, but Tifana insists, stating her elf heritage makes the age difference irrelevant.

Tifana takes Cain to meet the king, where she announces their engagement, shocking everyone, including Cain’s father, Garm. The king reveals that Tifana’s lineage makes her proposal akin to one from a princess. When informed of Cain’s secret engagement to Telestia and Silk, Tifana remains undeterred and declares her desire to marry Cain even stronger. The king, intrigued by Cain’s abilities, questions his extraordinary strength. Cain eventually reveals he retains memories from his past life in Japan and regularly meets the seven gods, who granted him his incredible stats and the title of "God’s Chosen." The king, astounded, commands everyone to keep Cain’s secret, even suggesting Cain could be king, which Cain firmly declines.

Recap

Cain reads a magic text written by the first king, Yuuya Terra Hirasawa Esfort, who recounts his life in Japan and how he reincarnated into this world. While Cain is engrossed, Silk and Telestia interrupt, curious if he’s studying for the royal academy entrance exams. Cain dismisses their questions and excuses himself. Tifana approaches him, suggesting a mock duel, but Cain declines, citing other obligations. It’s his twelfth birthday, and he heads to the Royal Capital Guild Headquarters to register as an adventurer. There, a red-haired adventurer named Claude greets him, advising him to value his life and be cautious. At the front desk, Cain completes his registration with Retia but chooses not to include his noble title, assuming it irrelevant to adventuring.

As Cain prepares to leave, a group of men harasses Retia and confronts him when he intervenes. Despite their aggression, Cain dodges their attacks effortlessly. Before the situation escalates further, Claude steps in, revealing his strength and admonishing the men. He introduces himself as part of the Ice Flame party and commends Cain for his skills, even offering advice on adventuring and showing his A-rank card. Claude’s wife, Lina, interrupts, urging him to stop idling and complete their quest. Cain takes his first quest: defeating goblins in the eastern forest with no upper limit on the reward.

Outside the guild, Cain encounters Tifana and Daim. Hearing about his quest, Tifana insists on accompanying him, leaving Daim in charge of the knights’ training. As they venture into the forest, they find a destroyed carriage surrounded by goblins. Cain heals an injured man while Tifana fends off the goblins. When green lizards appear, Cain instructs Tifana to take the man to safety and defeats the creatures using Ice Pillar. Elsewhere, adventurers Nina and Millie stumble upon the aftermath of Cain’s battle and marvel at the destruction before heading home.

At the guild, Cain asks Retia if he can claim rewards for defeating the green lizards despite not taking their quest. Retia is astonished, as green lizards are typically part of D- and C-rank quests. When Cain reveals he defeated thirty, Retia alerts the chief, Cedric, who accuses Cain of fraud due to his G-rank and recent registration. Cedric threatens to revoke Cain’s guild card, dismissing Retia’s protests as abuse of authority. The commotion draws the guild master, who laughs off Cedric’s accusations. He introduces Tifana as his sister, shocking Cain and the others. The guild master reveals Cain’s noble status as a baron and son of Margrave Garm, prompting Cedric’s apology.
Tifana praises Cain’s strength, noting he defeated a red dragon at ten years old. The guild master decides to promote Cain to A-rank if he subjugates bandits, surprising Cain, who had just started as an adventurer. The gods, observing Cain, discuss the increasing commotion he causes and the necessity of his strength to face the impending danger of Aaron’s seal breaking. They agree to arrange special training for Cain under a skilled individual.

In the after-credits scene, Telestia and Silk excitedly plan a study date with Cain in the library, only to be interrupted by Tifana, who proposes a beach date. Jealous of Cain’s attention toward Tifana, Telestia and Silk scold him for declining their earlier invitations, demanding he grovel to make amends.

Sylvia wakes Cain in a panic, fearing he’ll be late for his royal academy entrance exam. Cain reassures her, quickly prepares, and teleports to the school on time. After receiving his exam details, he notices he’s unfamiliar with anyone in his group but assumes Telestia and Silk are in another room. He completes the written portion in just 30 minutes. During the magic assessment, Cain asks if he can use his full power, and the examiner assures him the barrier around the academy will hold. Opting for a beginner spell, Cain’s Fire Bullet destroys the target, the barrier, and the surrounding land, shocking everyone.

Meanwhile, signs of an impending monster onslaught arise in the Forest of Monsters. Cain discusses the situation with Djinn and learns of increasing monster aggression. Despite concerns from guild members Millie and Nina, Cain ventures into the forest alone, accompanied by his holy beast Haku and dragon Gin. Unable to pinpoint the source of the disturbance, Cain summons Seth, who detects a powerful presence and deploys Dalmatia, a demon subordinate that specializes in investigation. Near Aaron’s location, Dalmatia’s presence triggers Aaron to unleash the onslaught, ordering monsters to attack the humans. Seth informs Cain of the imminent threat, prompting Cain to organize defenses. He sends Claude and Lina to gather adventurers, instructs Tifana to lead the knights, and prepares to confront the threat directly with Seth.

TL;DR

Recap

Seth informs Cain that he and his subordinates will handle the onslaught of monsters while Cain focuses on defeating the ringleader, Aaron. Meanwhile, Nina, Millie, Claude, and Lina join the battle in the forest to support Cain. Seth's subordinates, shocked that their master has contracted with the God’s Chosen, begin subduing the rampaging monsters. Cain engages Aaron, who is in a weakened dragon form, and summons Haku and Gin to assist him. However, Aaron quickly overpowers Haku, and the rest of the group struggles against the endless wave of monsters until Tifana arrives with reinforcements.

During Cain's intense battle with Aaron, Gin shields Haku from Aaron’s devastating beam attack. Cain, determined to protect everyone, activates the powerful "Saint Sanctuary" ability, creating a massive pillar of light that annihilates Aaron and leaves a colossal scar on the ground. Seth and Dalmatia comment on Cain’s overwhelming display of power and confirm the onslaught has ended, securing the town's safety. Cain reunites with Tifana, Millie, and the others as Seth and Dalmatia take their leave.

Later, the king questions Cain about the massive pillar of light and the rumors of divine intervention. Cain explains that he used emperor-level magic when intermediate-level magic proved insufficient and admits that the Prince of Darkness aided him, shocking the king further. Overwhelmed, the king jokes about abdicating in favor of Cain but instead grants him the title of Viscount and the domain of Dorinthol. Cain enthusiastically accepts, despite the objections of Garm, Daim, and his fiancées, who warn that Dorinthol is plagued by corruption due to the adventurer's guild's abuse of power. Cain remains optimistic, eager to rebuild the domain into something new.
The king learns of Cain's tumultuous experiences in Dorinthol. Upon arrival, Cain is assaulted by the guild under the guise of a welcome party, which he easily defeats. In a pub, Cain defends a young waitress from abusive adventurers but is arrested by corrupt guards. Cain later confronts the church for demanding excessive tithes and eliminates both the guild and an underground faction planning to harm a priest. To cap off his actions, Cain constructs a castle even grander than the royal palace, leaving everyone astounded. While recounting his stories to Silk and Telestia over tea, Cain encounters Seth and his wife, Lefane, who reprimands Seth for his infidelity. After Lefane asserts her disdain for cheating, she and Seth reconcile and leave.
