Huh? Wtf are you talking about? She left to find Fukatsu for help because she didn't have strength to support Takan and run away from or fight the other guy at the same time OBVIOUSLY. Also obviously she didn't think the other guy would be hurt by the bully. This was all obvious even before the next chapter that comes after the one coinciding with the timing of your post above was posted. Please read more carefully. Dfba.
She was going to defeat the guys but her friend didn’t want her to ruin her makeup. She knows her other friend worked hard and wanted to show the guy she likes, it’s understandable. Even if she did defeat those guy they would of captured him and the whole thing would of happened. That’s how I see it correct me if u don’t agree ╮( ̄▽ ̄)╭
Mirei is getting on my nerves, also hated how tomose left him just because she wanted fukase to see her makeup. Like, bich, he likes you for you not whether you look like a girl or not. Also, I think he would hate it more if you had actually left someone in trouble for your own safety. Smh.
