YAIBA: Samurai Legend

Yaiba Kurogane has spent his days training in the jungle in order to attain his goal of becoming a real samurai. By a twist of fate, he returns to Japan and starts living with the Mine family, who are connected to his father, Kenjuro. Yaiba constantly baffles the Mines' daughter Sayaka as she witnesses his wild and reckless ways. One day, Yaiba tags along with Sayaka to school and has a fateful encounter with Takeshi Onimaru, a kendo expert. Yaiba and Onimaru repeatedly clash, and as if in response to their search for strength, two ancient powers are unleashed: the Fujinken, the Wind God's Sword, and the Raijinken, the Thunder God's Sword. Both supernatural blades that have jolted the world since ancient days have reawakened...and the truth behind them is revealed!
