Big Fist (大たい拳けん, Taiken?): Big Fist allows Itsuka to enlarge one or both of her hands to enormous sizes.[2] Itsuka's hands become gigantic (around three times bigger than her own body) almost immediately. Her physical strength also increases in tandem, giving her enough power to easily crush tungsten shields, knock out people with a few strikes and carry heavy objects with her.[3] Itsuka herself does not seem affected by the increased weight of her gigantified hands.
