<report>After 100% clearing this VN, I can conclude it's a waste of time. Except for that boss fight. And the voice acting. They're both so bad it's good. The voice acting for Sol is just... 10/10 laugh every time. If you really want to read this, just do Kuku's route and one of the three main ones (Luni, Ellie, and Mitsuko). Kugari's route is the only male one, and it's really bad.
Overall: 3/10
It has saves and the skip function works fine. Would've given it a 2 if the character Sol didn't exist.
