My name is Ryuzaki Luca, half an angel, half a demon. While most people of my age would consider having supernatural abilities a cool thing, it really isn't as easy and fun as it seems. You can go from having a swell time with your friends to having a demon try to drown you on dry land. 

I'm a first-year student at Kuzusaki High School, and my friends and I have formed a club to uncover the secrets that lie within our prestigious school.

While the four of us are connected by one goal, we would soon realize that uncovering the secret of the Black Flame isn't the only connection we have. While at it, I keep getting into more and more trouble with the women I know.

Even though I'm steeling myself against developing feelings for anyone, it's becoming increasingly hard to do that now. I started Kuzusaki High School as any ordinary kid, but things are getting even weirder now, while strange occurrences keep pulling us deeper into the conspiracy.
