This is my first review please be gentle~
It makes me go AAAAAAAAAAAAAAAA and here's why:
Gril protects Teache, Teache wants to protect his students. Gril is a student, but Teache can't protect her from fights. School administration: "imo everyone for themselves I want personas to break because something something," thus building a setting for great characters, and great fights.
There are many fight scenes, each very detailed. What I love most is the way the characters overdo their emotions, (anger can be grotesque, cute is super cute). These portrayals is great for this kind of manga. It's definitely up there in terms of uniqueness.
Teache - At first I hated him, I thought he'd be like every other copy paste teache. Later on (midway from where I am now), he undergoes serious character development. I'd say Teache isn't the main focus, although he's sort of the main cause of everything that happens when he's in charge of decisions.
gril (main gril, probably main character) - CUTE! STRONG! She's probably more of the main character than teache. As you're reading through, know that she's still a cute girl and has girly emotions and such.
The supporting characters are really what make this manga great (later on, a couple ten chapters in things get serious). There's not that many in the beginning.
NOT PUTTING THIS DOWN ANYTIME SOON. WAITING FOR TRANSLATIONS.
READ IT. SPREAD THE WORD. I WANT DOUJINS TO BE MADE.
