So the first one they killed. Muramasa.
There other from this series is Jushiro Ukitake.
These are both animated characters, yet the way they were built and created makes me feel for them. Makes me love them. The same cane be done in novels, which I plan to use. I'm not sure yet is I use any of these writing tools in my current work, but until I'm done with this series I sure won't get them out of my head.
