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 cold water feels so good!
!الماء بارد ومنعش
¡Qué fría y agradable se siente!
¡Qué fría y qué gustito!
L’eau est froide ! C’est agréable !
L'acqua fredda è proprio piacevole!
Que gostosa essa água geladinha!
Какая приятная прохлада!
