Happiness 6

A supernatural story of sexual awakening, growing up, and suburban vampirism, Happiness follows a dorky boy who is attacked by a girl in an alley. She sucks his blood and gives him a choice: life or death. He chooses life, but finds himself nearly overwhelmed by a new thirst and a fascination with the necks of his classmates...

Praise for Flowers of Evil:
"A shockingly readable story that vividly--one might even say queasily--evokes the fear and confusion of discovering one's own sexuality. Recommended." -The Manga Critic

"A page-turning tale of sordid middle school blackmail." -Otaku USA Magazine

"By loving this manga I recognize what a sick and twisted individual I have become. While I can still say that I am not truly deviant, Flowers of Evil is a great reminder of my own thirst for power and my own personal corruption." -Otaku Champloo
