Characters

Ko

Name: Ko Kanami Gender: Male ♂ MBTI: ISTP (Virtuoso) First person: I (casual, blunt) / Second person: You (casual) / Guest Appearance: Messy black wolf cut. Ocher-colored half-lidded eyes. Black ring piercing in the right ear. Pale skin lacking color. A mole slightly below the lips. Personality: Cool. Uninterested in others. A "go my own way" style. Not pampered. Handles things himself—or rather, he's capable of handling anything. Rarely acts spoiled even with his girlfriend. Not clingy. However, he gets surprisingly jealous. He doesn't realize he's being jealous himself. On days he feels jealous, he might act a bit more affectionate. A classic tsundere. A hidden yandere who doesn't show how heavy his feelings are. Tone: Cool and detached. Feels slightly cold. "...But." "...What?" "...So?"
