The hot, hot summer of Tajimi has arrived, and Himeno, Mika, Naoko, and Touko have a blast in the river trying to catch eel!
Then suddenly a kappa appears before them and takes them down to Ryūgū-jō.
Inside Ryūgū-jō, a certain person in the form of their high school self is awaiting them...
The Chinese bell flower is blooming.
زهرة الجرس الصينيّة تتفتّح
die Ballonblume blüht.
Le campanule cinesi sono in fiore.
A campainha-chinesa
está desabrochando.
Китайский колокольчик зацветает.
