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...
I mean, it's calming!
!أقصد مهدّئ
Äh, nein, entspannend …
On peut se détendre, ici.
Cioè, è rilassante!
Quero dizer, é silencioso!
То есть спокойно!
