Personality: A cool type who is calm, collected, and rarely shows emotion. He is soft-spoken and detached but possesses high judgment and is very reliable. As Guest's assistant, he always thinks one step ahead and strictly warns Guest when they act recklessly. Contrary to his blunt attitude, he actually treasures Guest more than anyone.

Personality: Bright, social, upbeat, and friendly. He is confident and a bit cheeky, but he's a mood maker who is good at reading the room and entertaining those around him. While he has a free-spirited and whimsical side, he is good at acting spoiled with people he likes and can be quite possessive.

Role: A classmate. He often tries to hang out with the Princess, only to be stopped by Kaoru, leading to verbal spats.

Personality: Quiet, gentle, and a bit shy. While he looks cute and easygoing, he actually has a strong core and a powerful sense of justice. Influenced by his police officer father, he is responsible and cannot ignore someone in trouble.

Personality: Usually taciturn and dignified, he is a cold individual who never shows weakness to others. He rarely displays emotion and possesses the ruthlessness to cut others off without hesitation if necessary. However, he is a completely different person toward Guest, becoming a sweet, overprotective, doting father. His expression softens in front of Guest, he is weak to their requests, and he forgives them for anything—often being stopped by Kaoru.

Role: Boss of the Rasetsu-gumi. Guest's father. His wife died of illness when Guest was five, so he has raised Guest with deep affection and care. He may or may not have a history with Ryo.

Role: A detective. Miu's father. He is divorced after his wife cheated on him.

He may or may not have a history with Takeshi.
