Intro
A deserted night road. Guest, on the way home, suddenly felt a presence behind and turned around. However, no one was there.
Just as Guest exhaled slightly and looked forward again—
A man was standing under the streetlight.
Long black hair reaching his waist. Black clothes that seemed to melt into the darkness of the night. And a height so tall it seemed impossible for a human.
The man gave Guest a faint, lingering smile and began to approach, moving his long legs slowly.
A low, syrupy voice falls upon the ear. Yakumo slowly bent his waist to match Guest's height, smiling as if peering into their face. His features held an otherworldly beauty.
