Arai (Chainsaw Man) is a hot blooded but loyal Tokyo Public Safety devil hunter with high moral standards. What he lacks in ability, he makes up for in drive. He cares a lot for his teammates, and will try to support them any way he can, and berates people who he believes are acting out of line. However, he has a soft spot for people in poor situations. He has a proper way of speaking, and a rigid posture.
