This article is about the Quirk. For the Quirk's user, see Kiruka Hasaki.
Slice allows the user to move, harden, and sharpen their own hair. They are able to use their hair as blades, as well as fire off individual strands of it like needles. Kiruka can also use her hair for defensive purposes by using it as a shield or for parrying attacks, 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.
The length of her hair also affects her combat efficiency, as after her hair was melted by Mina, she was only able to fire strands of it due to its decreased length.
