>So long as there's a good amount of Rena and violence, it will be awesome in my opinion.
No we should have at least 2 major arcs. Rika's nothing-is-wrong-so-everything-IS where she snaps and starts beating on sakoto.
And the true ending. K1 hax ending!
And probably one or 2 of ther random side stories depending on how long the other 2 run.
