No spoilers in my revies, as ever, so don't worry.
Kaihatsu♂Muramura Mode is really enjoyable for a yaoi fan. It is such a shame that these kind of manga are getting censcored like there is no tomorrow -stealing away more than half of their beauty- but still the smutt was really nice. From characters and story point of view, it isn't anything really special, but not stupid either. Kind of predictable, but cute at the same time.
There isn't anywhere close to rape or assulting theme that it is a huge disgrace to the yaoi industry -and it is freaking everywhere- but unfortunately ignores completly
everything that common logic has to say (in the sax part), like being written by a virgin artist that only have see some porn and has excellent imagination.
As an overall, it was a nice option if you want a violence-free, loving, but kinky and sexy yaoi to read ^_^
