Kanade sheltered Sakuya after she was given up by her father, although their relation, if they even have one, is unknown. He is a university student, but has made few friends and is apparently "taking a break", according to Sakuya. He is presented as a lazy and difficult person, making people younger than him (like Sakuya) work. Sakuya defends this behavior, as she doesn't mind working and because Kanade saved her.Despite this,Sakuya is very important to Kanade.lately in the manga Kanade started to work as a construction worker as a sign of responsibility. Wikipedia He was not good at studying even though he tried his best, and had pressure because his parents told him study more careful whenever he didn't do well. He is the first person to accept Sakuya because he got abandoned by his parents after his explosion and tried to kill his father.
