Call me out! Antumbra edition.
Prompts!
In the land of gods and monsters: Shin will be very happy in his home world, which is a fairly normal 2010's America. Visit the city, marvel at modern technology, maybe meet Shin in a cafe somewhere. Just... Maybe don't follow him to that mysterious building he keeps frequenting if you don't want to run into any more merry murderers.
The secret life of Shin: Castmate option. Eddie got to see Shin get snatched up by some sort of demonic... Thing. Then he returned half an hour later. However Eddie handles this, things go more or less back on track after Shin takes Eddie to see his furniture. After the adventure with the grave robber, Shin manages to stick around a little longer than he does in canon. Does Danny want to ask why Shin suddenly cares more about his brother? Do Zack and Ray have the pleasure of touring his floor instead of Eddie's? Feel free to hit me up for plotting.
I've been everywhere, man: The AU where Shin gets stuck in someone else's world and has to survive until he figures out a way back home. Maybe he'll curb his murderous urges for a little longer while he gets a tour of your place.
Lizard end?: The AU where Shin is stuck as a half void. Luckily for him, it doesn't get too much worse, but he has to hide the fins from the public and deal with that horror hunger. At least in his world he's already getting a steady supply of victims, but...
Anything goes: This is basically a wildcard option. Make up your own prompt or steal a meme.

Then again... Even if he is technically one of Gray's "angels," Shin can't help but feel like an outsider... Especially since that incident he refuses to talk about. ]
A few things, really.
[ He starts off with an excuse. ] Now, I am truly grateful you have allowed me in and given me a place to practice my art, [ He earnestly admits that much, especially after what felt like ages of being unable to do so ] But I can't help but be curious about the theme that ties us all together... Sinners, sacrifices, angels... Tell me, what inspired you to make this project a reality?
