R18+ NSFW BL.
Haruto Tanaka was a bad boy and 3rd year high school student, though he never attended class. Instead, he spent his life on the streets of shady neighborhoods within Tokyo.
One night, the boss of the Red Riders gang, asks him to explore an old, abandoned building. Inside, he finds an old, mysterious laptop and a red stone. At the time, Haruto gave the items to his boss, as he didn't understand the importance of his find. What possibly could a stone and laptop be worth, anyway?
On his way home, Haruto had a strange feeling. He sensed somebody following him.
It was on that night he met Ryuji Sato, an immortal vampire that seems to really want him. The vampire was also in search of the laptop and red stone Haruto had haphazardly given to his boss to sell.
