The story in Cosmo na Bokura! is uninteresting to an almost bizarre degree, with stakes so low, you can't help but wonder why it's even been put on paper and published by professionals. The dialogue and character motivations are aggressively dumb and often very childish.
Haruko, the main character (AKA Cynthia) is repeatedly referred to as a witch despite the fact that she never does any magic whatsoever and doesn't seem to possess any powers beyond... luck; in fact, she doesn't do much of anything at all besides playing rock paper scissors. Rarely have I seen such a passive protagonist (she doesn't even do much in the way of reacting!). Everyone else is a carbon copy of archetypes that have been done and redone much better elswhere thousands of times. The only interesting one is Chika, and she's an only slightly alluring outline of a potentialy better character.
The art goes from mediocre to actively ugly with nary a symmetrical face. The best pieces are by far the cover art for the volumes.
I would only recommend Cosmo na Bokura! to aspiring writers and mangakas as an example of what not to do. Anyone else can move along without giving it a second thought.
