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...
Oh, you're right.
ماذا؟ أنتِ محقّة
Nanu? Du hast recht …
¿Eh? Es cierto.
¿Eh? Es verdad.
Ah, tu as raison.
Oh, hai ragione.
Ué... É mesmo.
О, и правда.
