[1] The staple gameplay mode, Great Transformation, allows characters to take on child or adult forms, the Puyos used by them becoming smaller or bigger respectively.

The game opens with a storm of Puyo falling down onto Earth, flooding a high school in its wake.

Ringo Ando, a student who witnesses the flood, trembles until Arle Nadja appears.

During most battles, she is able to use a special ability: she can transform into an adult or a child while playing, which affects the size of the Puyos she uses in the process.

After a match with Klug, Ringo decides that in order to solve the problem, she must travel to seven power spots of the planet, encountering the strongest opponents.
