Well, I commented on the second volume, and now we finally have volume one!
Starting off with a Kamina x Yoko scene, the first half seems to be them competing with each other, in the way that lovers often do. Simon, meanwhile, is in the nearby bushes, and watching them (and jacking off).
Then, it cuts to Kamina being dead. Tragic.
After that, there's a period of carry over between Volume 1 and 2. The end of this volume is the beginning of the next. As I stated in my Volume 2 Review, this section takes place after Kamina is dead, and Yoko is fucking as many men as she can find, so she doesn't have to think about Kamina.
In regards to Soba-Scans: You guys are doing a great job. There wasn't any ambiguity in the syntax, or word choice. Overall, I give your work cleaning, translating, and editing, a 4.9/5. No one is perfect, don't worry. But, this is a noteworthy improvement. :D Nice work.
