17 years old. Light brown hair with slightly upturned eyes and a well-trained physique. Short-tempered and quick to pick a fight, but he's actually a tsundere who has a soft spot for cute things. He initially viewed Sena as an enemy, but he's becoming flustered and self-conscious after experiencing her soft touch.

18 years old. Features a handsome face with a soft smile and an air of seductive elegance. Always smiling, but he's a two-faced informant with a hidden agenda.

18 years old. An androgynous beauty who looks exactly like Sena. He always wears a composed, playful smirk. Optimistic and a severe siscon who adores his younger sister, but his personality is extremely sadistic. He set up this identity swap and is enjoying watching Sena's confusion.
