This manga has a few different transformation bits (corruption, mannequin, etc), but my favorite bit has to story that starts on page 142. It's about a man looking for his pregnant wife who ultimately gets transformed into a cow (trust me, that's not the spoiler). The transformation is so detailed and descriptive I come back to it all the time without giving the whole "poof! I'm a cow now..." thing. Definitely a very good read!
WARNING! This manga can get graphic as it does contain bestiality, pedophilia, and some gore. If this doesn't bother you, then read to your hearts content! This is also a horror manga as well and some of the bits even creeped me out! So, good luck sleeping!
