Itsuka Kendo, hero name Battle Fist, serves as Class 1-B’s elected representative at U.A. High School, praised for her leadership and maturity. Often called the "big sister" of her peers, she maintains unity by curbing Neito Monoma’s provocations toward Class 1-A. Born September 9 in Chiba Prefecture, this 16-year-old O blood type embodies traits linked to determination and athleticism. Her hero costume blends a teal qipao with a black corset, navy boots, and a domino mask, later updated with long sleeves for winter. Post-graduation, she rises to No. 23 Pro Hero, sporting a muscular build and a sleek back-of-head ponytail. Her Quirk, Big Fist, enables her to enlarge her hands, wielding enhanced strength for combat, rescues, or defense—such as shielding allies from toxic gas. A signature move, Double Jumbo Fist, involves striking with normal-sized hands before abruptly expanding them mid-impact to amplify force. She demonstrates tactical ingenuity by dispersing Mustard’s gas with wind from her enlarged fists and crushing Momo Yaoyorozu’s tungsten shields during the Joint Training Battle. Ranking fifth in the U.A. Entrance Exam with 65 points, she excels in rescue operations. During the Forest Training Camp, she deduces Mustard’s location through gas diffusion patterns, and in the Joint Training Battle, devises counterstrategies against Class 1-A. Though analytical, she occasionally lets rivalry influence decisions, as seen in her clash with Momo. Combining thoughtfulness with a no-nonsense attitude, she mentors classmates like Tetsutetsu Tetsutetsu during the Forest Training Camp, their teamwork securing Mustard’s capture. Empathetic toward Class 1-A, she shares exam tips and addresses Monoma’s antagonism. Her internship under Uwabami emphasizes practical heroism, despite initial frustration with publicity tasks. Outside heroics, she favors black coffee and motorcycles, embracing a tomboyish style. During the U.A. School Festival, she showcases combat skills in an impromptu beauty contest to engage the crowd. Evolving from class leader to pro hero, her journey underscores unwavering dedication to justice and collaborative strength.
