@Kyrieo How? His family? Or the delinquents? His family would complain but in the end they would understand. The thugs can taunt all they want, it doesn't do anything. If they look for confrontation, he is still Nanba and damn strong. Let it be a warning just because he retires he can still fight. There is nothing in improving one's life
His school would be supportive. Helping civilian life and not causing trouble. Trouble found him because of his name when he tried to retire his delinquency.
