Description

Autumn has arrived at Verbena Academy.

This summer, Lithia, the princess of the divine world, was finally able to become lovers with Raito, something she had dreamed of since childhood.
As she experiences autumn in the human world, Lithia becomes melancholic and contemplates their future.

"What Raito-kun and I need the most right now... is a concubine!"

As their love blossoms into marriage, Lithia wonders if they should have a traditional two-person wedding or if polygamy is the better option.
As she daydreams about the future, Lithia becomes conflicted about the differences between human and divine cultures.
While the gods practices polygamy, perhaps it would be the better choice for their marriage too!
Lithia begins her search for a concubine in secret from Raito.

Meanwhile, a mysterious airplane suddenly appears on the Verbena Academy grounds!

"Could Raito-kun's father be alive...?"

The plane's appearance and the amnesiac girl on board set off on an enchanting journey at Verbena Academy in autumn.
