A hardcore gamer is reborn when he chooses to play on Hell Mode difficulty. Now he needs to figure out how his summoning skills work. While still a baby.

Little does Allen know that the Appraisal Ceremony will expose the brutal reality of playing on Hell Mode.

Allen experiments with his Summoner abilities, unaware that a coming crisis will remind him that the world he treats as a game is a harsh reality for others.

Allen decides to tell his parents about his abilities.

Allen's hunting strategies have paid off, but the fledgling summoner still has a long way to go. Especially when he must now deduce the purpose of his new storage skill.

The baron wishes to observe Allen's boar hunts firsthand. If he's impressed, there may even be a reward; one that could change both Allen and his family's life forever.

Allen begins his new life as a manservant of the Gravelle Family. Fortunately for him, that doesn't mean the end of a life of monster hunting.

Allen's uncanny ability to hunt monsters earns him a promotion, and the baron's family awaits a visit from the eldest son. Life is good. For now.

Allen realizes he's still got a long way to go after a B-rank monster attacks the city. If he wants to face the challenges ahead, he must unlock his class's true potential.

Allen may have figured out his class, but that doesn't mean he's figured out the world.

Allen merely sees the Armored Ant colony as a test of his abilities. He has no idea that victory could lead to political consequences.

Allen and Cecil have a long, dangerous road ahead of them. Reaching safety means facing more than just one threat.
