First of all, wow to this manga. One of the few anime that I watched and jumped straight to the manga for continuation. Although i continued reading the manga, i preferred to wait and see if they will continue the anime series, which i think it deserves period.

Funny
Suspense
Cheering Kitano
School vibe is good
Hilarious teachers
Don't judge people just because of the way they look vibe

I would recommend this manga to anyone. But you should watch the ova 1 and ova 2 before jumping to the manga. Which i have downloaded the completed volumes. Moreover, the events that Kitano is faced in the school and challenges he overcomes is entertaining, funny and the classmates he meets and protects. As well as the fighting is SICKKK!!!!!!! and Kitano always find a way to win. Although he is always thinking of something unrelated to the fight with the person lol
