Haruka is now a member of the Little Busters! Which means we're just two members away from it the main cast being complete. I assume Kud will join in episode 8, 9 at the very latest, with Mio apparently in episode 10. Spoiler:- Considering they haven't gone the way of a semi-omnibus type set-up:
I like how Kud is just there for no reason other than to get some screen time, looks like we get an full episode of her next week though. Riki better ask Kurugaya to be Kud's roommate, because her reasoning for not doing it is just great. I assume Kanata will eventually be the roommate though.
So, you're fortunate enough to not have watched Kira.Window-kun?
