>>6800103It's literally just a visual novel where you're a bartender in some small bar on the street, who talks to the various people who come in about their lives or problems. Events kinda happen around you, and you hear about it from others. P-much the only choices you as the player can make are what drinks to serve, and sometimes, how alcoholic you make them.
You start getting regulars over the course of the story, and you should memorize their drinks and serve them when they seem particularly troubled if you want to get slightly different endings.
There is something of an overarching story, but it's more cyberpunk than anime IMO.
That said, it's really good. The music is fucking awesome, the characters are pretty fun to listen to, and it even references 4chan a bit (especially /u/).
