fuunsaiki

Master Asia's mount. He is a white horse with a dark gray mane and a swatch of red on his forehead. He can also pilot his namesake mobile horse via the Mobile Trace System.

On a more comedic note, the "Go For It, Domon!" 4koma series implies that Fuunsaiki is the first student of the School of the Undefeated of the East, and thus outranks Domon Kasshu.

Note: Since the horse and the mobile horse he pilots have the same name, the tag applies to both.
