Big Fist (大たい拳けん Taiken?): Itsuka's Quirk grants her the ability to enlarge both of her hands to a gigantic size. With the increased size comes enhanced striking power and gripping capabilities. Itsuka's increased strength allows her to carry people and lift her enlarged hands without a problem, as seen in her fight against Mustard. Her enlarged hands grant her proportionally increased chopping and gripping strength. During Round Two of the Joint Training Battle, she proved to be strong enough.
