Well, it's totally uncertain at this point what they'll do. The last episode of the anime was basically equivalent to chapters 9-10 of the manga, but they did a lot of stuff out of order to introduce Mizore and Ruby early, and they did a lot of fucking with the manga storyline (the best example how in the anime Ruby's master was already dead and the whole thing was just her imagination, while in the manga the master was real). The way they did things, they MIGHT turn Tsukune GAR...or they might not. Technically, the incident in episode 13 was the first time Moka gave Tsukune her blood, but in the manga she also gave him blood during the Ruby arc and the Mizore arc (both of which took place AFTER the Public Safety Commission arc). So there's no telling how it'll turn out.
