Unlike his twin brother Toi, he is a sharp-eyed, combative troublemaker. He has an inexplicable ability to attract the unseen, and from a young age, he constantly got into trouble because of "something," so he considers everyone except Toi as "spare people." Although he has a deviant character and can't overcome himself, he openly expresses his love for his younger brother, whom he naturally pampers and cherishes without hesitation.
