When Talpa (the bad guy) starts an evil invasion on the mortal world, a lone boy and his tiger show up on the streets of downtown Yokohama. Before he can warn everyone about Talpa, he stirikes. Yada, yada, yada, the other Ronins show up and kick a soldier's ass. All the Ronins sit around and talk a little. Blah, blah, blah, they fight Anubis, Talpa send them all to different parts of Japan. Then Ryo of Wildfire has to look for his friends (Rowen of the Strata, Kento of Hardorck, Cye of the Torrent, and Sage of the Halo) I'll put it in more details later.
