Let me start by saying that only 3 chapters were ever released, and according to Baka-updates I believe it has been dropped/discontinued permanently. So, I still suggest reading this if you are a fan of Yoneda Kou but just don't hold your breath on this ever being completed.
Based in samurai times a gang of assassins get a new member, Shikon. Shikon is young, sharp, cocky and gives the other members a run for their money from his skills and personality. Shikon clings to Saiga (a quiet, mysterious existing member) who ends up staying with him and so the story progresses...
The story is kind of hollow.
These guys kill people because of given orders from their boss (unknown at this point) and there is only one action scene. The rest of the story is dialogue and character building. So, really the story focuses around Shikon and Saiga and how their relationship grows leaving the rest of the story in the dark. The boy love themes are very light. There are a few suggested moments but nothing happens. The art work is great and doesn't leave you disappointed in the eye-candy-department (as the new guy sleeps naked all the time). I'm a huge fan of Kou Yoneda and have read many of her works because of her art.
In the end, this is a great start to an interesting story...that looks like it will never be finished. As it's only 3 chapters long, I'll leave it up to you on whether you wish to read it or not.
