We meet again PineTree(billdip and Dipper as Kokichi au)

In this AU the ending is like the ending from number 2 where everyone is alive(?).Kokichi goes back to gravity falls to see his sister and soos.(along with his grunkles of course)but because he still has Kokichi's personality as well as a bit of Dipper's,he is smart,a lier,good at hiding his emotions, is extremely curious about the paranormal/unnatural and because of Danganronpa has tried to end himself(multiple times).
When he gets to the Mystery Shack,he finds out that his Grunkles never came back from the trip to the ocean to explore the unnatural things there(this is said at the end of Gravity Falls(the thing about Stan and Ford going to the ocean,not never coming back))and that they died from an unnatural beast.
His sister and Soos are there waiting for Dipper to come back,but when he comes back different then what they remember,they stray away from Dipper(mainly Mabel,not Soos).Dipper on the other hand is having dreams about Bill and Nightmares of Danganronpa.So one day he tries to end it all by summoning the dream demon himself.
