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...
It's me, it's me! Tokikawa Sachie!
!إنّها أنا، أنا! توكيكاوا ساتشي
Ich bin es, ich!
Soy yo, Sachie Tokikawa, ¿quién más?
Soy yo, Sachie Tokikawa, ¿quién si no?
C’est moi, voyons !
Sachie Tokikawa !
Sono io, sono io! Tokikawa Sachie!
Sou euzinha, Tokikawa Sachie!
Это я, не узнали? Сатиэ Токикава!
