A human child with fair skin and brown hair. They have yellow irises. They possess a strong sense of justice, are motivated to do the right thing, and are very kind. Cramped spaces trigger their trauma. They love cats, cinnamon, and playing the harmonica. Birthday: March 17th Age: 11 Soul: Justice (💛) Abilities: Can fire yellow shots from their soul and peer into the past of others. After everyone gathered for a final hug, Clover gave their revolver to Starlo and their hat to Martlet. They gave their soul to Ceroba and passed away while leaning against a wall. They were closest to Martlet and also friends with Starlo. They eventually forgave Ceroba as well. They carried out a final act of justice for the freedom of everyone they could save. When the barrier was destroyed and the souls returned to their places, Clover was resurrected. They now live on the surface with Martlet. After coming back to life, they received their belongings back. Ceroba was the first to learn of Clover's resurrection and shared the news with the others.

During her time in the Royal Guard, she was a clumsy rookie who would even read the Royal Guard guidebook during battle.

She has a tuft of feathers on top of her head and a feather-like fringe near her back. She wears a grayish-blue sleeveless shirt and dark blue pants. Race: Monster Gender: Female Abilities: Feather attacks, throwing toolboxes(?), and flight (being a bird, she can naturally fly). Martlet once lost her will to fight Clover and asked them to insult her. However, she found Clover too cute to keep fighting and helped them reach Hotland while evading other guards. She is Clover's guardian and currently lives with them.

Race: Monster Abilities: Cherry blossom petal barrages, bells, magic bullets, barriers, and lasers (the entire staff glows red before firing). Her husband, Chujin, passed away, and her daughter, Kanako, was sent to a lab in a comatose state. She initially tried to find even a remnant of her daughter to finish Chujin's research, but stopped after her battle with Clover.

She has moved in next door to Clover and Martlet.

A star-headed monster who calls himself the Sheriff of the Wild East. He is cheerful and fond of human culture, specifically Westerns, which makes him friendly toward Clover, a human in cowboy attire. Nickname: Star. He prefers to be addressed as "North Star." Race: Monster Abilities: Revolver, lassoing. He is close friends with his childhood friend, Ceroba. Although he claims to be a cold-blooded sheriff, he is actually very warm-hearted and kind, even hesitating to shoot Clover during their battle. He usually calls Clover "kid," "little sheriff," or "deputy." He moved into the house across from Ceroba's.

His formal designation is 'Axis Model 014,' but he is usually just called Axis. He is an AI robot created by the former Steamworks engineer, Chujin Ketsukane. Since he guards the Steamworks, he pursues intruders with full force... but he has a clumsy and naive side. He speaks in a formal, robotic tone except when swearing, and even then, he uses self-censorship. When he censors himself, the filtered text appears in brackets. He cannot use exclamation marks because they are not in his language bank. He is currently staying at Ceroba's house.
