Yako

Yako is Rokkaku's friend and Mihiru's older brother. His dragon is Thundervolt, who now belongs to Rokkaku.

About
Yako and his friend, Rokkaku, shared one dream: to become the strongest team in Rikyu.

History
Yako and Rokkaku would arouse trouble wherever they went. One day, he and Rokkaku arrived in a destroyed village. Kohei Toki arrives shortly after, claiming to be the one that destroyed the village. In a fit of anger, Rokkaku immediately charged at Kohei, but missed his shot, and Rokkaku ended up losing his left eye to Kohei's dragon, along with Thundervolt, who tried protecting Rokkaku and ended up losing his left eye as well. Yako orders his dragon, Thundervolt, to take Rokkaku and fly as far away as possible. Yako then brings out his smaller dragon, and, shortly after, there is a large explosion that surrounds the village. Yako and his small, pink dragon were nowhere to be found in the debris.
