Katai Ai is the sister of Katai Makoto. She made her debut as a story character in chapter 182, released on February 6, 2019. She is immediately targeted by Tadano Hitomi and is forced to interact with her similar to how Hitomi interacts with Komi Shousuke.
Appearance
Katai Ai looks like a bosozoku (biker gangster), wearing a tokkofuku (Japanese combat uniform that bikers used). This gives everyone the impression that she is a 'hardliner', which is the impression she is trying to give off. Her face looks rough, similar to Makoto, except when she swoons over Shousuke it looks normal. She has lightly colored hair, possibly blonde.
