He's honestly way better off not attending school. It's just going to get in the way of his grind. If anything, if he really wants to get a party, he's better off getting that girl to learn some skills, partner up with him, and immediately get into power leveling asap if the school is just going to feed him incorrect or useless information for three years.
Anyways, time to level up the Sword proficiency? If so that'd go against the title. Waiting to see how this story ends up forcing him into using only the club. Or if the title was just bait and in reality he's going to learn every weapon required and revert back to his old Fisting ways.
