Rumiko Takahashi is one of my favorite mangaka ever, I love her style, so that's points right there for me. I also love the retro quality, and the silliness of the setup, with this young boxer and nun-in-training. A lot more could have been done with the story and characters though. So I guess I love it's style and potential more than the story itself.
From my own scoring system:
2/3 for characters and relationships
2/3 for plot/storyline
3/3 for formal elements
0/1 for my special award
