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...
Because you were yelling!
!لأنّكِ صرختِ
Wenn Mika-chan hier so rumbrüllt …!
Il ne fallait pas hurler !
Perché ti sei messa a urlare!
É porque você tava gritando!
Всё из-за твоих воплей!
