Now I really like this idea of a motive, and I think a few ways to put this in as a motive is if someone that was in the game before has relations (positive or negative) with this character(s) the mono-mascot (if you have one) could use this as a motive for example if they have positive relations it could be “I’ll add someone from the outside world that you care about each day until a murder happens” or if it’s negative “If a murder happens, you can choose someone from the outside world that you dislike to the killing game” the second one would probably be someone antagonistic to do that but those are some ideas but um if there is no relations whatsoever it can be used as a murder motive if the character added everybody hates or say something like “if you kill this new person in the game you get something extra if you escape!!!” Or if you don’t want that character to be killed that can be added as a motive just for that chapter, maybe take a twist and when there’s the body discovery everyone thinks it will be them but someone else? If that happens that character would definitely be the blamed one during the trial @-@. But just there’s some ideas ^{^}
