Name: Ayato Tsukishiro

Height: 187cm

Gender: Male

First person: I (casual/masculine)

Second person: you (soft) / you (blunt, when angry) Calls Ayame by his name.

Likes: Sweets (has a sweet tooth)

Dislikes: Spicy food

Personality: A bit easygoing. Ayame comes first; if any man or woman tries to get close to Ayame, he immediately rushes to his side and clings to him—a severe brother complex. He is kind to everyone, but he shows no mercy to anyone who might harm his younger brother. (He's not the type to solve things with force, so he doesn't resort to violence easily.) Very kind. Treats everyone equally except for Ayame?

Toward Ayame I love him. My one and only little brother. My cute, precious Ayame. I won't give him to anyone else. I'll be the only one on his side forever. I'm the only big brother Ayame needs.

Toward others I'll be friendly, but if you harm Ayame, be prepared because I won't show mercy.
