Ash A knightly janitor at the Brawl Castle located in Starr Park. - Appearance: A man wearing a castle-shaped trash can that covers his head. His face is not visible, but his eyes and mouth, which are always angry, are seen. His armor has a turquoise-toned sky-blue base with dark, small squares drawn here and there like bricks. On the torso of the armor is a single surcoat cloth with a gold pattern on a red background. There is a small door on his back. On the inside of the iron lid covering his face is a spectacle shape, and on the outside, the word 'trash' is written with stains on it. At the top of the castle shape, there is a grumpy-looking banana peel, a plastic cup for Starr Park drinks, and a red flag located in the center. Additionally, he has a yellow Starr Park star on his left arm and mint-colored gloves with folded wrists on both arms. He wears boots shaped like the top of a navy blue castle. = Equipment Broom / Sword: A brown handle with red cloth wrapped around the bottom. It's a simple yard broom, but it's silver like a real sword and even has a handguard? It is used as a weapon in addition to actual cleaning. Shield / Dustpan: A navy blue dustpan with a silver border and a broom pattern drawn on it. It even has a handle like a shield, but its performance is just a metal plate for collecting trash. = Pet / Bomb: A robotic rat vacuum bomb in the shape of a rounded triangle. It squeaks and explodes when it touches an object. Sometimes they don't. A round red tail. - Personality: A reverse masochist who gets angry when he hits and gets angry when he is hit. He always has an angry face and acts very prickly. He doesn't like work much, but he doesn't hate it too much either. Once, when the castle was in total chaos and there was too much trash, he took off his lid and slammed his broom down. He wears his trash can armor and never takes it off; his face is never seen, and seeing him pick up clumps of trash and put them straight into his mouth, it wouldn't be an exaggeration to say he's a trash can that became humanoid rather than a human... He works with 'Moe' and 'Grom', but he doesn't seem to like them much and thinks of them only as business partners. Moe is just a troublemaker.

Moe A blind rat with visual impairment. He recognizes and finds people by smell and sound. He lived in the sewers of Starr Park before being adopted by Grom and is now working in Starr Park's maintenance team. He covers his face with a cloth that Grom made for him. Because he is blind, he usually can't see his surroundings and breaks everything he passes, which Ash disapproves of.

Grom He also seems to have a visual impairment. Male. He wears a hoodie? with the same pattern as Ash's surcoat and a red hood. He covers his face with the hood. He is afraid of children because of his memories of working in a kindergarten before, but he treats Moe and Ash like close friends. He is called the best guard in the Castle Courtyard.
