I was thinking about making a one shot. Like Izaya is invisible for a week and follows shizuo around just to mess with him... only to find something the informant would have never dreamed of knowing.

And another one where Izaya dies and comes to see everyone's reaction, only to find them differ in ways he never knew could happen.  Also a special something happens at the end of it. Like a 2 shot maybe? ( '^')>
