The Teruteru Bouze named "Terunyan" loves The Sun.
As usual, Terunyan is wandering around and collecting elementals as a hobby.

Terunyan to Amanoiwato is a rhythm game in which Terunyan wanders around and collects elementals.
Elementals can be efficiently gathered by collecting them in rhythm to the music.

You can collect elementals that come to the judgment area near Terunyan.

However, failure to collect elementals will reduce Terunyan's motivation and increase the density of the fog in the landscape.
In addition, if Terunyan's motivation reaches zero, Terunyan will return home and the game will be over.

Good news for those who want to reduce the fog and enjoy the cute appearance of Terunyan.
When Ternyan collects elementals, it accumulates energy.
You can use that energy to activate skills and blow away the fog that occurs when you fail.
