this is my first review, sorry if I make many mistakes but English is not my original language. this spin-off really sucks, if in Kyochuu Rettou we have an interesting, innovative, complex story with beautiful drawings, here it is quite the opposite, there is almost nothing plot only of the worst ecchi scenes I have ever seen, and then not to mention the characters, they have no interesting features, the drawings are really discreet not to say that they make you vomit. the only thing I found interesting in this manga was the professor who taught everything about insects to Oribe Mutsumi who finally makes an appearanceafter seeing her only in oribe Mutsumi's flashbacks in the original series.
