Battles & Events


Denki Kaminari

Denki tried to hit on her by asking for her phone number, seemingly she wasn't interested.


  • Kashiko's name is composed of "red" ( seki?),"outside" ( gai?),"passable" ( ka?),"viewing" ( shi?) and "child" ( ko?).
    • When combined together, her family name means "infrared" (赤外 sekigai?) and beginning of her given name means "visibility" (可視 kashi?), both of which are references to her Quirk.
