Volume Overview
Azusa's family continues to grow, with Halkara joining the household and even Beelzebub becoming a frequent guest of the group.

Time goes on, and Flatta village begins preparations for its yearly festival. Azusa, normally one to shy away from activities that would attract attention to her, stuns the village by agreeing to participate after a request from the village elder - something she has repeatedly declined in the past.

For her contribution to the festival, Asuza decides to do a one-day limited pop-up Café out of her home, with Laika insisting on making it maid themed, much to Azusa's surprise.

Meanwhile, Halkara begins preparations to set up shop in the town of Nascúte, but she encounters more than she bargained for after she purchases some property for her new business venture.
