In order to gather the Stellar Beasts which hold the power of the stars, a young Star Druidas named Selena embarks on a journey to mysterious worlds through Door-kun. The great adventure to return everyone in town and her family begins! A classical fantasy by the well-renowned official illustrator of Hatsune Miku and the like, LEN[A-7]!

In the future, an app debuts that can simulate your romance with a partner of your choosing and calculate the compatibility score. Is this a way to have a romance that never fails? What is it that people look for in a romance anyway?

This series has adult situations and some explicitness, but not the level you'd usually expect from LEN[A-7]'s other works.
