Something in the anime is bugging me, the only reason why shinigami cant leave Shibusen is because of the kishin? so what is he doing now staying in the school now that they are in a bigger pinch since its going to be like kishin, arachne and medusa agaisnt shibusen? and why is it that shinigami is just staying in the academy instead of helping them with their missions which could produce better results. this is just an opinion though.
