No is not that one, idk if it have manga version or not. but i remember she's not magical idol but she solve crime and stuff, she's transform to busty looking lady and solve crime but i remember she have penguin, she also have another pets but i dont remember what are them.
I forgot if the penguin can talk or not, but i remember it was funny kinda different than other magical princess maybe the author is male. i also remember one particular scene where she was groped by old bald men then she stomped his feet, the scene is on the plane.
