In the land of the Sword Galaxy on the 2nd plante Mafia CIty. There are many anime, manga, comic, and movie references; like the cafe shop from Tokyo Ghoul "Anteiku", the bar/tavern from Seven Deadly Sins "the boar hat", and so on. Basically there are many forms of Dinners, Cafès, Bars, Stores, Guilds, Taverns, and so on.
There are other planets with those but the first to be in the sword galaxy is " The Fire Tavern ''. Daspit its name it is more like a hotel dining hall than anything. But the one thing that I don't understand is why they chose that name of all things. The sword galaxy is a weird place I know that much but that makes some people avoid it but there food is good.
