Nakashima Tsubaki

Ikenai Hokenshitsu The new infirmary teacher is hot, but he's kind of perverted!? He reads porn, too. A very dangerous man indeed!! Just what's going to happen to Mimi, the health committee member!? Toilet no Hanao-kun Dan x Boi! Panic at the pool Count 10!

From Shoujo Manga Maniac: Kojima Mitsu (a.k.a. Honey) is in middle school (She's 12 years old) but she's so small that she looks like she's in elementary school! One day while she is is changing into a maid uniform for a school event (with not much success…the uniform is too big for her), she find a little bat blocked by the window and helps it. Suddenly an awesome guy appears in front of her! He is a vampire and as thanks for saving his "toy," he helps turn her into an adult (with a kiss)…
