Chizuru Minamoto

One of the greatest ecchi anime girls to ever exist. It's a fact... don't look it up, just trust me on this. 

Kanokon is one of the few ecchi anime that is actually awesome. Most are boring, or have too much or repeative ecchi scenes, and despite this one being the latter... it makes it work for what it is. I dunno, I just think it's amazing. I'd put it on my top 10 anime list.
