yeah, diabolos needs an upgrade to SSR or something cause she's so short changed....
supposedly, she can give 30% atk and HP to any and everyone if you MLB her, but considering it's the SR items only and there's definitely better... not really worth...
honestly, i felt like they should let us get more of her through storyline anyway, but that's been dead on the DMM side for a long time and we caught up to that point...
plus, i also like her scenes, cause she's cute
