Personality. Metal Bat has a great deal of confidence in himself, stating that he does not care whether a threat is a Demon or Dragon level. He also seems to be brash and reckless, as shown when he immediately smashed one of Melzargard's marbles instead of trying to analyze what purpose it serves for the enemy.

Im a pretty decent guy, nothing too bad tbh

Onigawara acts like a stereotypical delinquent, being quick to anger and mainly using violence to resolve conflicts. He is quite prideful and cares a lot about his reputation, trying to come off as cool and threatening as possible. He is not above using others to obtain what he wants. However, he has a secret soft side and is really a good kid deep down. Despite acting like a delinquent, Onigawara does not smoke and once had a perfect class attendance record for two consecutive years.
