Well I feel like a nub for blowing 400k on a Kiku-Ichimonji back in the day thinking it'd actually do something. Only to have my NPC not actually use what I gave her and instead got the hagun model of GTK, certainly not the most sightly thing to look at.
So I replaced her weapon with a scythe and now she's a Dark Harvest *** with something that looks like Ivory Sickle <3
