Well that's certainly... extensive. Also, Monster Girl Quest? Ah well.

The character looks fairly powerful, but you haven't really detailed the strength of many of his abilities outside of vague terms such as 'very strong', which could refer to anything from cut-through-steel to slice-planet-in-half. While I'm fairly certain I have a decent idea of how powerful this guy is, I'd appreciate if you could give some more solid measurements of his strength.

Also, you don't need to actually list each of his individual sword techniques. Just for future reference. You could have merely written down that he had various powerful sword techniques that can be boosted with his elemental spirits, together with a more-less approximation of how powerful these techniques are. This helps skim down your CS a bit, and makes it more readable for others.
