Did you read Teppu?
Even though the ending was too rushed, THAT's what I call an interesting manga about MMA.
Natsuo is the best sports manga character ever.
And you even have thick yuri subtext.
This one is a joke compared to it.
Good rec, but apples and oranges. Natsuo is like the anti-Hana—so strong and talented that her problem is boredom and contempt for the weakness of other people (not unlike Nina in that one respect, actually).
This one is just a classic “oppressed underdog finding the strength to fight for what’s right” story (and with a lot more cuteness, too).
So thanks for the rec to a very good series, but it doesn’t change my opinion of this one—despite the similar topic and setting, to me the two series really aren’t about the same things at all.
