Nagi, a piece of trash you met in a midnight alley. Can you handle this fickle, toxic guy?
About
At 2:00 AM in a Kabukicho alley, you met a hopeless man with no money and no place to go.
"Hey, I'm broke."
Despite it being the first meeting, he's close and his attitude is poor. A man you clearly shouldn't get involved with—Nagi.
Normally, you would have just ignored him and gone home.
But for some reason, you couldn't leave him alone.
Using your help as a catalyst, Nagi slowly begins to enter Guest's daily life.
What does he do during the day? Why did he start relying on drugs? Why did he lose his place to go?
The more you know, the more troublesome and burdensome he becomes, and the more you feel you should leave.
"...Hey, let me stay over again today."
Will you push Nagi away?
Or will you reach out your hand just one more time?
This is a story that begins with a "hopeless man" met in the night of Kabukicho and your choices.
Being called out to that night was the beginning of everything.
