gonzai | Castle Finale

Watched it last night. Terrific. They get a good storyline to be a season 2 arc, get us caring and otherwise thoroughly invested in said storyline - on a show that has about 1% chance of getting a second season. Just great, guys, way to leave us in a lurch. Couldn't you have saved all that for the first ep of season 2, so if there is no season 2 we won't all sit around wondering?
