Aspara-Seijin are two of the crossover characters from Pop'n Music 8 that originally appeared in KEYBOARDMANIA.
Occasionally, they're hanging around to play, pupupu...and landing on Earth, but they're innocent in mind. These two are brothers (?).
The Aspara-Seijin brothers possess aquamarine skin with three legs, blue eyes and are wearing sky blue clothes with magenta pink arrows on them. The alien on the right has his hood in the shape of an arrow pointing upwards and his clothing patterns on the left direction, while the other is vice-versa. Their original palette is recycled in コルトーン from Pop'n Music éclale.

The Earth is still changing into a perfectly round object for a long time~☆
From the sky, pupupu~, to the right, it's an uproar!
