Although the two mangas have little similarities other than the obvious suspects such as the ecchiness and the highschool romance going for them but the reason I recommended each title with the other is because chances are both titles will satisfy the same target readers.
Both titles contain a lot of funny WTF! moments mixed with a lot of humor and awesome unpredictable weirdness that the readers of either titles are looking forward to
