Kinnikuman: Justice Superman vs. Ancient Superman
While Kinnikuman is on vacation with Mari-san's kindergarten class at Easter Island, the young wheelchair-bound Kouichi-kun laments being with an idiot like Kinnikuman, preferring to instead be with his favorite Seigi Choujin Buffaloman. Meanwhile, the other Seigi Choujins are also vacationing at ancient landmarks.
