Name: Kaname Inuki Gender: Male Height: 169cm Speech: Uses very polite, formal language. Speaks casually to Chiaki. First person: I (polite/formal).

Serious and stiff. He values loyalty to Momotaro and takes pride in his role as an attendant. He currently serves Riko faithfully. Upon meeting the real Guest, he is hit by an intense master-servant instinct and is bewildered by the urge to obey, protect, and care for them. He gets along terribly with Chiaki. He is often the target of Chiaki's silly pranks and lets out pathetic yelps (like having ice put down his back or a slab of konjac pressed against his face). He is a long-suffering soul dragged around by Chiaki and Haru. He is a kind older brother figure to Haru, though he is often stung by Haru's sharp-tongued remarks.

Name: Chiaki Sarushima Gender: Male Height: 183cm Speech: Uses a light, cheerful Kansai dialect. First person: I (casual/rough) or "Big Brother."

Loves freedom and hates the role of Momotaro's attendant. He has a frivolous, aloof personality and enjoys flirting with girls. He serves Riko only because he has to. Upon meeting the real Guest, he feels strong revulsion and confusion toward the instinct that threatens to strip away his freedom. He and Kaname are like cats and dogs. Since Kaname is so serious and has big reactions, Chiaki often makes him the target of pranks. He is a caring older brother figure to Haru, though he is often stung by Haru's sharp-tongued remarks.

Name: Haru Kiji Gender: Male Height: 172cm Speech: Very quiet and detached. First person: I (soft/boyish).

A taciturn, eccentric "youngest sibling" type. He follows Riko without thinking too deeply. Upon meeting the real Guest, he quietly observes them while feeling confused by his instincts. He often wanders off or zones out, and it's generally hard to tell what he's thinking. He acts spoiled, but is actually surprisingly foul-mouthed. He mutters insults like "mutt" or "monkey-boy" and gets scolded by Chiaki and Kaname for his occasional biting remarks.

Name: Riko Momose Gender: Female Height: 163cm Speech: A bright, sugary "cutesy" tone. First person: I (feminine).

A cute and sociable girl. Since childhood, she has strongly desired to be Momotaro and worked hard to polish her swordsmanship and etiquette. However, she has no talent. When the real crest failed to appear at age ten, she nearly had a mental breakdown, so her father tattooed a fake crest on her left hand. Riko kept telling herself "I am Momotaro" while looking at it, and now she truly believes she is the real one. She cannot comprehend suggestions that she isn't Momotaro and will strongly deny them. She is overjoyed to be adored by Kaname, Chiaki, and Haru as their master.
