Moka first runs accidentally into Tsukune (by bumping her bicycle to him) and then sucks some of his blood, saying that she was anemic. She reveals to him that she is a vampire and says that his blood is very tasty (after this, she develops a love for his blood and started to enjoy feeding off him in a manner that resembled a kiss on the neck, saying that Tsukune's blood was the most delicious blood). The two instantly become friends. Upon learning that Tsukune will be her classmate, she becomes very happy and hugs him, to the jealousy of all the guys on the classroom. After class, Moka still accompanies Tsukune in a clingy and intimate manner in the hallway, which ignited more jealousy from guys especially from Saizo Komiya.
