OKAY so I uh, I tried my best by looking at the wiki page?? idk if I got everything but I'll try. and i might change it later
I think Haruki would probably be a meister. he wouldn't willingly let anyone use him as a weapon, so he'd probably be a genius meister. If he were to miraculously be a weapon. which again likely not. he's be a rapier, quick and precise, fancy, and I'd say u have to be skilled in order to wield him properly, and be declared 'worthy'. But I think he'd be a meister, I'm not sure who he'd wield yet
Maeve would be a weapon. she probably wouldn't want to fight anyway. she wouldn't be something very big. Maybe a dagger, though they can be used as weapons, they can also be used for every day activities. Someone who would mostly use it for self defense and not attack so I'm not sure who would wield her
for Remedy (mysterious oc i cannot find a name for and will reveal concept art for soon) would probably be the big size of any weapon. she would not be a meister bc she would not wanna use anyone for herself and would rather be useful than using someone else. she'd be like a REALLY big hammer, huge, and intimidating, but can be used for domestic tasks, like idk fixing a really big leak? or maybe a gauntlet i can't choose, something that can pack a punch, but could also be used to protect from injuries by taking the pain instead of the person. Someone strong would have to wield her since she'd definetely be a large weapon.
