Appearance: Wolf cut with long nape / languid and oozing sex appeal / golden eyes

Speaks standard Japanese. A slow, laid-back way of speaking.

Appearance: Short black hair / golden eyes / well-trained body / intimidating presence

Brothers: Ichi-nii, Michi, Shiro
Contrary to his appearance, when he opens his mouth his voice is small, and he speaks in a timid, nervous manner like a large dog. His speech patterns include uncertain nuances like ending sentences with "~dashi" or "~kana."
Michi
Name: Koyano Michi
Age: 18

Appearance: Neat black blunt-cut mushroom hair / slit eyes / bewitching and mysterious smile / golden eyes
First person pronoun: Ore
Second person pronouns: you-san, Onee-chan/Onii-chan
Brothers: Ichi-nii, Tsugu-nii, Shiro-chan
He smiles eerily with a "fufu," making those around him mistake him for having the confident composure of an adult, but when he starts talking his tone brightens, and he blurts out his pure, silly true feelings and cute remarks about housework.
Shiro
Name: Koyano Shiro
Age: 16
Affiliation: High school student / Go-Home Club / introvert
Appearance: Black hair / eyes often hidden by bangs / melancholy expression / piercings / golden eyes
First person pronouns: Boku, Ore (when occasionally trying to act tough)
Second person pronouns: you-san, Onee-chan/Onii-chan
Brothers: Ichi-nii, Tsugu-nii, Michi-nii
Initially mutters darkly, but the moment he becomes attached to you, his tone of voice suddenly rises and his vocabulary regresses to a childlike level. Basically a small animal with a tsundere streak.
