Description
Kerioiru is a character from the anime Reborn as a Vending Machine, I Now Wander the Dungeon. He is the leader of an adventuring party known as the Fool's Oddities Brigade and is easily recognized by his distinctive cowboy-style clothing. He is a skilled combatant who specializes in fighting with knives, particularly excelling in close-quarters situations.

In terms of personality, Kerioiru has a somewhat casual and informal approach to leadership. He is known for delegating undesirable tasks to other party members, often engaging in playful banter with them. Despite this tendency to push work onto others and his sometimes teasing demeanor, the internal relationships within his party are genuinely good and the members get along very well with each other.

Kerioiru sees great value in the protagonist Boxxo, believing that the vending machine's unique capabilities are indispensable for achieving his party's long-term goals. Consequently, he makes active efforts to recruit both Boxxo and the powerful fighter Lammis into his group, though these attempts are not initially very successful.

A significant moment in his role within the story occurs during a battle against the floor boss known as the Eight-legged Crocodile. Facing a difficult situation, Kerioiru makes the tactical decision to temporarily leave Boxxo behind. This choice backfires when the floor cracks and Boxxo falls to a lower level of the dungeon. When Lammis, who had been unconscious during the battle, later regains consciousness and learns what happened to Boxxo, she becomes furious and confronts Kerioiru directly. He is then forced to hurriedly accompany her to retrieve the fallen vending machine.

A key development regarding Kerioiru involves the revelation of his personal life. It is disclosed that his fellow party member Filmina is actually his wife, and the other members Aka and Shiro are his children. This means that the Fool's Oddities Brigade is not just a group of professional adventurers but rather a family-operated party, with Kerioiru serving as the father and leader of the unit.
