Kenyuu Densetsu Yaiba Pilot

Yaiba Kurogane is a wild young swordsman who has grown up treating danger as training. After returning to Japan, his overwhelming confidence and unconventional upbringing put him on a collision course with Takeshi Onimaru, a rival whose own swordsmanship and ambition refuse to be overshadowed. Their clash opens the door to a much stranger battle than either boy expected, where monsters and legendary blades make ordinary schoolyard rivalry look harmless.
