This AU is pretty scary/gory, so watch out for that (btw Doodles sorry for the entrails bit in the prompt chapter lol).

So basically, in this AU, Orange/Rainbow is a serial killer. Kind of if you swapped the roles of the Killer Secret AU (which is also up to be claimed btw), except Orange/Rainbow's reasons are much different.

As it's hinted in the prompt chapter, Orange wasn't treated very nicely in his earlier years after being sent out of the village. Being left out in bad weather, barely getting any help from people, and having to deal with the wilderness as just a kid didn't do much good to him, so he has a lot of issues. Aaaand those issues lead to him becoming a serial killer.

Orange had been killing long before Sabre arrived, and when he did, Orange was just more careful with his 'work'. As Sabre and Orange became better friends, however, Orange didn't really know what to do. He had never really had an actual friend like he saw Sabre as before, because his past and his closed-off nature always driving most people away. Orange, after turning into Rainbow, became very possessive/protective of Sabre. He never obviously showed it, but a a change was noticed. Nobody said anything, though.

There could be a point where he gets caught and goes into hiding like I put in the second prompt chapter with this AU, buuut Imma leave this one to interpretation now =>=
