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 think you were dreaming about it.
لعلّكِ حلمتِ بها
Por eso soñaste con él.
Por eso habrás soñado con él.
Tu l’as vue en rêve, c’est ça ?
Devi essertelo sognato.
Acho que você acabou
sonhando sobre ele.
Тебе, наверное, сон приснился.
