So I read the review of Creamy Mami at http://www.themanime.org
And here is the recommended audience tag:
This anime was intended for little girls, so aside from a brief panty shot in the first episode when Yuu is being lifted up into the spaceship, it's OK for little kids of all ages.
Maybe that first episode was meant to trick boyfriends into watching this anime with girlfriends who are still young at heart?
Or maybe someone is just writing strange reviews over there.
