Oresama Teacher

Both are freaking hilarious and have similar characters. Involves a strong girl(with funny reactions and great personalities) making friends with a yankee, along with another person as a love interest (both of which have a pervy side).
Although Oresama Teacher centers more around comedy, both have some action to it as well as have the main girls with some zeal/personality to them. These two mangas are definitely worth the read! :D
