So, Seo is conspiring with Komachi to blow up her classroom, while at the same time the Prez is trying to kill her off before that happens, so Satsuki is too distracted to save her, so she cannot be there in time to save her class? I realize that the Japanese high school is the most interesting and intense place in the entire world (Manga-land), but this is some spy novel-level of gambit pileup...
On the bright side, it warmed my heart to see Satsuki use the proper firefighter door breach technique. Never smash doors with your shoulders, people, or you'll break your collar bone. Human legs are capable of applying much more force and are a lot more durable.
Mngh . . . . why didn't anybody give Seo a pair of scissors?
I mean, it probably wouldn't do great against an extension cord, but at least she could've done something more to save herself . . . . especially since it was actually her tie.
Maybe they did not want to place another potential hazard near her? There is a reason people are told not to run with scissors.
At this point they could probably call the police on prez.
It will be three witnesses against two, without any video evidence. Would be tough, but manageable if the teacher backs them up. On the downside, I think they are going to have a lot more trouble with the exploding classroom than with the Prez at the moment, giving him just enough time to clean up any remaining evidence.
