I think these two would make a great couple. These two hit it off in the first episode and it becomes better and better. When the schools finds out Tsukune was a human, Moka does not hesitate to protect him. The others seem to find it hard to expected it, so it shows Moka loves Tsukune even if he is human. Plus Tsukune let's Moka feed from him and he cares for her even if she is a vampire. In the second season his mom tells Moka that Tsukune talks about her a lot and how she helped him when he first went there, I mean that screams romance. Let me know what you guys think in the comments. (P.s this is the Anime not the manga).
