One of them is indeed Kondou Isami :3 I'm sure you will love what I did with him, but I have yet to finish his bio so for now I can't post it ~sadsheep

And the reason why I didn't use Gatotsu is mostly because it is Watsuki's name lol. If it was the original historical name I would have no qualms using it :p
