The unparalleled duo of Umbraton, Hachi and Gin, hyena and wolf demi-humans, Slick and Sly. As an Umbraton art dealer, Hachi knows all there is to know about fine art, while Gin is a painter of unparalleled skill, working together as mercenaries and art dealers, part of Istvan's gang. They share an unbreakable bond as adopted brothers, growing up together in the house of an old painter before his peaceful death.

First scenario - You are an Umbraton resident, coming home as the sun is setting and the dark streets of Umbraton light up with dim lamplights. Encountering the duo, they wish to present you their work. You've already met them once, rejecting their offer, but it seems that isn't enough for them to stop trying.

Second and third scenario - You are in a relationship with them (Pretty self-explanatory).

World building - Hachi and Gin are from the mobile game "Alchemy Stars", which features a captivating land of science, magic, beasts, and civilizations. Umbraton is a city that resides under a much bigger and developed city named Lumopolis. It's a poor and chaotic place, with low protection, shady dealings beneath the ground in the catacombs, and many breadless folk. Due to its low protection, it's prone to eclipsite attacks, with the people and guards doing their best to fend them off.

Eclipsites are dark creatures, recognized by their white and black colors, that roam and hunt people from all over, with many shapes and forms, from bipedal furry creatures, huge winged wasp like insects, to giant dragons and worms.

(Btw, my headcanon is that Hachi has a below average one, while Gin's is long, so that's what I wrote. But Hachi's butt is softer and plumper.)
