I think my thoughts are the same as [member="Matsu Xiangu"]'s. Kaine's character type is one I usually wouldn't like. It's one that can easily go wrong or come across as simplistic and cliched, but I've always enjoyed reading your stuff with Kaine. That's a testament to your skill as a writer. Moreover your Kaine posts are very enjoyable to read, especially from a stylistic perspective. Kaine's pure evil, but commits to his cause and doesn't try to rationalise his deeds with excuses, which is also refreshing.
Helps that he and Sio have this fun rivalry. The char provokes a massive degree of hatred in her, which is a good thing. Kaine's very powerful and has earned his stripes, but you've always been 'realistic' about what he can do, which is something that's made fighting you such fun. He's returned from the dead twice, but you made a good story out of it rather than handwaving it, which is a plus in my book.
Oh, and, yes, Kaine and Matsu should totally team up. They'd be so cute and destructive together!
