Kimi no Tonari ni Suwaru Hoshi.

One day, a sparkling door opens before you—a door that leads to the world of stars.
It is on the other side that you find yourself face to face with twelve unique, vibrant princes, as well as their caretaker, a man whose face seems sculpted by the gods. The caretaker goes down on one knee before you and implores:

"Epilogia—the king's oracle. I beg you to lend us your strength and break us free from our doomed fate."

The king of the cosmos has gone missing, and make no mistake—it is YOUR destiny to select a new king and guide him to prosperity.

Now you must spend your days among the princes, building deep and bountiful bonds with them. Come be the light that will illuminate their path to a bright, shining future!
