Yuuna and the Haunted Hot Springs (2018 - 2018)

It's Kogarashi's first day of school! Of course, Yuuna decides to tag along, and gets Kogarashi into all sorts of trouble.

Kogarashi learns more about Sagiri, and she evens hires him for a job! Wait, is this a date? Yaya also starts following Kogarashi around for some reason…

Yuuna might have found a new friend! Meanwhile, Nonko-sensei needs a lot of help from Kogarashi.

There's a certain secret that Ms. Nakai can't tell the tenants at Yuragi Inn, but she still goes on that adventure. Meanwhile, Kogarashi tries to figure out what Yuuna's lingering regrets can be…

Yuuna and Koyuzu are running an errand when a young man they’ve never seen before suddenly calls out. His name is Genshiro Ryuuga, though he’s called the Black Dragon God, and he’s come to Yukemuri Town to find a bride.

Kogarashi, Sagiri, and Koyuzu carry out their mission to try and rescue Yuuna. However, Oboro, the Black Dragon God's attendant is a formidable enemy.

Chisaki comes to visit the Yuragi Inn on the weekend. She decides to spend the night and have a sleepover, much to Yuuna and Chisaki's delight.

Yuuna tags along to Kogarashi, Sagiri, and Chisaki's seaside school trip. However, through the suggestion of another Chuuma ninja member, Urara, Sagiri needs to buy a new swimsuit.

The sea side school trip continues as Kogarashi faces a monster that was accidentally summoned.

Everyone is enjoying their last few days of summer vacation. Kogarashi and Yuuna find themselves in Okinawa, and encounter another bound ghost.
