Ippatsu Hicchuu!! Devander
This story revolves around a spirited, carefree boy named Kazuma Harukaze, who lives with his little sister Sakura and his horse Lovely on a farm within sight of Mt. Fuji. One day, a "meteor" lands nearby, and it turns out to be Hinkeeru — a messenger from Muzanda who has come to warn Earth of a grave danger — and a robot horse named Robony.
