I personally generally find anime mods to be kinda cringe. However, there is ONE character in the anime/manga "Berserk" that I think would fit wonderfully into this quirky, weird, slightly sinister atmosphere.

Schnoz. The "Nose Thing". I feel like he would make an excellent character, and one could add various artifacts inspired by the story (Behelit, The Mark of Sacrifice, the Tongue Talisman that Creepy Dungeon Man Made, Donovan's Belt Buckle, etc) to round it out. Idea is free for anyone, so long as I get to play the mod.
