Choujuu Kishin Dancougar: Hakunetsu no Shuushou

After all the battles the Jyusenki-tai has been through, they have gone on their own separate ways. But one person will bring them all together again: Shapiro Keats. The man who sided with Muge Zarbados all the way back in the beginning is still alive. One friend-turned-foe awaits the Jyusenki-tai once again, in what will be their final battle.
