Alabaster no Kisetsu

Maeda Gin is a student who enjoys drawing graffiti at an abandoned apartment complex building near his school, with his friends and acolytes, Teppei and Kon-chan. One night, while they're at work on one of their masterpieces, they're interrupted by a mysterious ghastly pale-skinned woman who scares them. In the process of fleeing, Gin loses his sketchbook to her and then from this point onwards, his life will change in a major way! Some nude painting with his beautiful and attractive art teacher?
