durarara!!/ angel beats! AU

so basically I was thinking I haven't seen many durarara AU and I am in love with the anime and the novel I only have the first book of the novel but I'm working on getting more. anyway I think it would be cool to do a thing where the characters of durarara are trapped in the world of angel beats!. there soul mission ends up with them trying to find out how they died with some help from the characters from angel beats!. while dealing with the struggles of angel and everything else. also all the durarara characters wont be added in all at once the most they'll be added in is in threes depending on if I think they might have died together or at the same time. Also I could potentially be putting ships into the story including if I think a durarara character and an angel beats character would be cute together but we'll see how it goes. Also I kinda wanted to start with Erika and Walker or suizua. I also think there isn't enough erika x Walker fanart also I was thinking there should be this weird thing between Erika and shizua but you know that doesn't mean anything. Also I will only be using the main characters in durarara and this from like the original durarara.
