Chapter 84.5

Tsuyu Asui opens by presenting her household: her father Ganma, her mother Beru, her younger brother Samidare, and her younger sister Satsuki. Work kept both parents traveling, which left little of them for their young children, so cooking dinner and looking after the two youngest fell to Tsuyu. Hard as it was, she describes the life she had as a wonderful one.

In the years before U.A. High School, her middle school hero coursework swallowed whatever time she had left. Between that schedule and her frog-like looks, friendships never took. One classmate was struggling with the same problem from the other direction: Habuko Mongoose, who took to following Tsuyu around and repeatedly used her Quirk on her, a three-second paralysis inflicted on whoever she looked at. Tsuyu let it go, recognizing a loneliness that matched her own. She eventually worked up the nerve to ask Habuko to be her friend, and Habuko, moved, said yes. They graduated together but enrolled at different high schools.

Two years on, a day after classes start, a message from Habuko arrives: she has made friends at her new school and wants to introduce them next time. The distance between schools changes nothing for Tsuyu, who counts Habuko a friend for good, and takes it as a reason to go make plenty of her own.

Tsuyu's immediate family is introduced for the first time, along with the caretaking role she carried while her parents worked away. Her middle school classmate Habuko Mongoose and her three-second paralysis Quirk also debut, in a friendship Tsuyu initiated herself. The chapter closes on Tsuyu resolving to build friendships at U.A.

A five-page bonus chapter titled Tsuyu's Ribbity Diary, printed alongside Chapter 84 in the seventeenth issue of Weekly Shonen Jump for 2016 on March 28 and collected in volume 10. It introduces Ganma, Beru, Samidare, and Satsuki Asui as well as Habuko Mongoose. The material was adapted as the original video animation Training of the Dead.
