Ahhh.. Togainu no Chi. I love the manga the most, because the game simply is a yaoi game with a lot of pwp going on XD But it's also cool. The anime has too less plot going on, so the manga is the best source for Togainu no Chi >D It has plot, a bit of hints, but it's also ok to read for people who don't like yaoi/shonen-ai.
Back to the costumes. Akira was so comfortable and I love the character so much! Shiki and Akira suited us and our relationship so well >D *laughs* It was a lot of fun to cosplay as them and portrait a bit more of blood and violence, but we didn't intend to show senseless PWP scenes or too revealing stuff. We just wanted to show off their relationship and the brutality not the yaoi in itself. Also, we had a mere cellar - shooting and it was so interesting!
We had a little group with Kiki as Kiriwar and Kamikyo as Keisuke :)
