Black★Rock Shooter

From Worldsofharuhi

Black★Rock Shooter is a battle mode for Kuroi Mato. In her normal form Mato does not have innate skills, but in Black★Rock Shooter form, she acquires tons of innate skills that uses her blaster and kanata. Her slider power is 'vision', it allows her to see further or in slow motion or both. She uses this power along with her object which is sniper rifle.

Her innate abilities are really powerful, but she's still working on mastering her slider powers.
