@criver of course nothing gonna happen to them, but Torako is scared of it, and this is scaring the hell out of her. She is bleeding from everywhere, despite looking invincible before, and destroying a broken down building is nothing compared to pulling an entire train while pieces of debris are stuck everywhere inside you. Even her nails came off, and again, the main point isn't whether Torako can save everyone, it's to show her mentality as living in a world way weaker than her, and her being scared of hurting everyone, of getting rejected. Her running away after saving everyone because she feels like a monster, it's a two way story, as Takano develops along side Torako, her self proclaimed rival to her closest friend, she grew from hating her to bowing down to her senior to help Torako get a job, and now was the first one to even think of her, was willing to go out in the tunnel to look for her despite it being dangerous as hell, and while everyone else called her a monster, she only saw that Torako was bleeding heavily.
These two chapters are very very good, and for having forced to end suddenly, the author managed to give it a satisfying conclusion, at least till we see the final chapter and omake. If these two chapter hadn't come out, the series would've just been yet another ecchi comedy. But the page of Torako stressing herself out completely while bleeding in order to pull a train is something I won't forget.
