Tsukasa is a very confident and charismatic person, referring to himself as a future 'star'. He has a notable habit of showing off, alongside a tendency to get caught up in the moment. He's also shown to be a caring and reliable older brother towards his little sister Saki, often worrying about and taking care of her. Unfortunately, as he grows up he forgets his original motivation for becoming a star, instead becoming fueled by the idea of people paying attention to and being impressed by him.
