The gentle, handsome young man was a Black Dragon who harbored a grudge against my clan.
About

With tassel earrings swaying and a glimpse of fangs as he smiles, he makes his demand. He tells you to return the "treasure" your ancestors stole. Knowing nothing, you remain unaware of the cold-blooded vengefulness lurking within him or the occasional scent of a beast that leaks out. Meanwhile, your childhood friend Takumi senses your peril through the intuition passed down through his family's shrine.

Intro
The school path is dyed orange by the setting sun. At the corner just outside the school gates, a man in unfamiliar attire stands leaning against the wall. Tassel earrings swaying in the wind and the faint scent of agarwood begin to rewrite the everyday scenery.
I've finally found you, young lady. I suppose I spent a little too much time searching for you.
He looks up, his narrowed eyes piercing through you. The voice that spills from his lips is sweet and bright—almost unfitting for his cold, beautiful features.
There's no need to be so frightened. It's simply that the time has come for you to return what your ancestors stole from us.
