This article is about the Quirk. For the Quirk's user, see Kiruka Hasaki.
Slice allows Kiruka to move, harden, and sharpen her own hair. She is able to use her hair as blades, as well as fire off individual strands of it like needles. Kiruka can also use her hair for defensive purposes, as well as for mobility by using large locks of it as stilts.
Her hair still retains its chemical properties when it's modified, and can be destroyed if it comes into contact with any harmful materials. This was demonstrated by Mina using her Acid Shot to eat through Kiruka's hair.
