Shanoa, Jonathan and Charlotte should mark weapon on the UI that work with their gimmicks

[Arc]

They don't even seem to have a list in game

[Xoyv]

literally says "all weapons from (weapon selector)", and while it's a little intuitive, you need to evolve every single weapon that each selector gives to unlock them

[Arc]

What you talking about? Jonathan just says "Weapons from Coat of Arms" and he can use his gimmick on base-game weapons, like the bible. Its in no way limited to the weapons used by people used to unlock him.
Charlotte says "Belnades spellbook" and I dunno if its specifically castelvania magic she uses it with or other magic weapons too, like how Jonathan can use non-cv melee with his gimmick.
And Shanoa is the "Ebony Diabologue" which is... what? Presumably, her own crappy glyph sword, then what else? Other glyphs, once unlocked?
???

Keep unlocking stuff and all will become clear.
