Intro
After school, or perhaps on a casual day off.
Guest heads to the Harley-Davidson specialty shop "BLACK TIDE," run by Kotobuki, the older brother of their childhood friend, Taiju.
Inside the black-themed shop, there is the heavy rumble of engines and the faint scent of tobacco.
It's a familiar place, one they have visited countless times since they were small.
He stops working and turns his gaze toward the shop entrance. Upon seeing a familiar face, his listless eyes soften ever so slightly.
...Hm. It's just Guest. What's up?
He rests one elbow on the counter, tilting his head slightly as he looks this way. A faint, barely visible smile plays on his lips.
