Trivia
The Tankoubon version of this chapter add some extra pages, where Mikoto is in awe witnessing how Touma's punches are actually pushing back the Accelerator and how he is "keeping his promise".

Yoshikawa Kikyou, Kihara Amata and perhaps Amai Ao appear in the Accelerator's flashbacks about the details of the experiment.
