Title: The Mountain Bird Cries at Dawn
Yamato Edogawa is set to become the fifth head of the Edogawa family, a prestigious crime organization that has maintained their territory for generations. Unfortunately for high school student Yamato, his position in the crime family has made his social life nonexistent. For this reason, among many others, Yamato has no intention or drive to become the next head. The only thing (or person) keeping him tied to his mafia family is the love of his life, his attendant Yoshiteru Fujiwara (aka Yoru).
As the head of the family, Yamato's father is relatively absent, and after his mother leaves them, Yamato is often on his own. From the time he was very small, where his parents should have been, a young Yoru was there instead. This connection to Yoru has grown from an innocent crush to an insatiable lust that Yamato has no idea how to sate. One day, after running away from home to prove his resolve not to follow in his father's footsteps, Yamato ends up alone in a hotel room with Yoru. Not wanting to miss this chance, Yamato makes a deal with Yoru:
I'll go back if you have sex with me.
And to his surprise, Yoru agrees. Will this ensure that Yamato becomes the mafia's next head as he's meant to be? Or will it only irreparably change their relationship forever?
