Hino sure knows her stuff. Her takedown technique is damn good, she presses her head against Koguma's shoulders, preventing her to possibly do a front headlock. No wonder she skipped that class.
I'm glad someone else noticed this point. Just from that tackle alone, it's pretty clear that she's well trained. Can't tell how well exactly (it was only one move after all) but she's good enough that she can put things into practice without fumbling around.
Makes me wonder if she trained just so she could pin Koguma down with less trouble when the moon comes up..
