[Balzac]

Sassy-chan's included some stellar Masato/Little Busters dynamic comedy.

The first Rin maybe shouldn't have to prelude the second Rin, since the ending of the former would just give credence to Riki's whole narcolepsy issue for the audience. There doesn't have to be anything supernatural or fantastic - until Rin 2 comes along. That is if they decide to split it into Rin1 and 2 like the game.

For Saya, her route does have little interaction with her and the other members of the Little Busters. They could explore that in the animation for some original flavor (perhaps comedy written by dear old Jun...) The original route had her and Riki being by themselves for the most part, which could be jarring for the audience.
