The magical girl name was actually my doing since apparently there's actually a jewelry store called Diamondere and I thought it would be perfect for her, considering her personality... I'm also canon familiar with both Love Live seasons and Dia is actually one of my top favorites from Aqours, ahaha.

Nevertheless, I'm stoked to have her here; Zange should probably make the attempt to befriend her as Zange herself is an idol in her world.
