The Heroes are six classmates who leave Will-o-Wisp Academy in order to find their teacher, Miss Madeline, who had been missing for three months at the time. Althought their original destination was Puffoon, the wind planet, only Chai managed to succesfully land on it. Hero/Heroine and Lassi manage to crash-land on Erd, the Earth planet, and are also the first to leave their school. Mokka crash-lands on Cassia, the water planet, Chai lands on Puffoon, the wind planet, and Pico and Sorbet land on Gren, the wood planet. The classmates are all reunited on Razen, the fire planet, as foretold by the fortune teller in Tropica Village.
