Toaru Kagaku no Railgun Manga Chapter 138

Confrontation (対峙) is the 138th chapter of the Toaru Kagaku no Railgun manga series, released on February 26th 2022 in Monthly Comic Dengeki Daioh.

Synopsis
The two cliques in conflict remain agitated in campus despite orders from Hasekura Reiri to avoid confronting any member of the Mikagami Clique. While Misaka Mikoto and Kessai Kiyoshi talk about how unstable the situation is when espers and their abilities are involved, a few members of the Mikagami Clique see the defeat of Yasutoba Suika as an opportunity to fight back on the Hasekura Clique. One of them, Urui Aika, overheard loud sounds from the nearby riverside on her way home and sees Mikoto in the dark, practicing her new technique on the riverbank. Still remembering an intimidating encounter with Mikoto not long ago, she runs away only to stumble upon four members of the Hasekura Clique. The suddenness of the encounter caused the Hasekura Clique members to attack Urui, unaware that Misaka Mikoto is nearby, somehow assisting the outnumbered Mikagami Clique member.
