Description
Kerioyl is a character from the anime Reborn as a Vending Machine, I Now Wander the Dungeon. He is a man who typically appears in cowboy-style clothing and serves as the leader of a party known as the Fool's Oddities Brigade. Physically, he is an adult male with orange hair that is cut to ear length and gray eyes.

In terms of personality, Kerioyl is often portrayed as overconfident and arrogant. He has a tendency to push undesirable or difficult jobs onto the other members of his party, though this is usually part of a dynamic of playful banter rather than genuine malice. Despite his arrogance, he does demonstrate a caring side, as he considered abandoning a dangerous mission for the safety of his companions when they were nearly killed. One notable aspect of his behavior is a perverted streak; on one occasion, he patted an unconscious woman's rear, which led to him being scolded by another party member, Filmina.

The character's background and motivations are deeply tied to his family. It is eventually revealed that the Fool's Oddities Brigade is not just a group of adventurers, but a party composed entirely of Kerioyl's family. Filmina is his wife, and Aka and Shiro are his children. His primary motivation for targeting powerful foes in the dungeon, such as stratum lords, is to secure help for his son, who is in need of saving. To achieve this, he becomes a secret ally of a character known as the Netherlord, who promises to save his son in exchange for Kerioyl's allegiance.

Within the story, Kerioyl acts as a captain leading expeditions into the dungeon's deeper levels. He recognizes the value of the protagonist, Boxxo, a vending machine, and sees him as indispensable for achieving his party's goals, leading him to try and recruit both Boxxo and Lammis into his group. This creates a complex dynamic where he is both an ally to be worked with and a figure of suspicion due to his hidden agenda.

A key event that defines his early relationship with the main characters occurs during a battle against a floor boss called the Eight-legged Crocodile. Kerioyl made a difficult tactical decision to temporarily leave Boxxo behind, which resulted in the vending machine falling to a lower level through a crack in the floor. When Lammis, who had been unconscious, regained her senses and learned what had happened, she furiously confronted Kerioyl, forcing him to hurriedly go with her to retrieve Boxxo.

Kerioyl undergoes a significant development as his true intentions are laid bare. While he and his party are initially on good terms with the main characters, this relationship sours when his secret alliance with the Netherlord is discovered. Upon learning of his real objective, both Lammis and Boxxo turn against him.

In terms of abilities, Kerioyl is a formidable combatant. He specializes in fighting with knives and is highly skilled in close-quarters combat. Beyond his physical prowess, he possesses a notable secret ability that allows him to disable the blessings or special powers of other people, including the protagonist Boxxo.
