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...
Whoa whoa whoa Touko-senpai, why 
are you eating shaved ice?!
لحظة! لحظة! لحظة! لمَ تتناولين
!الثلج المبشور يا توكو-سينباي؟
Halt mal, halt mal! Warum spachtelt
Tōko-senpai da ein Raspeleis?!
¡Un momentito!
¡Un momentito!
Minute papillon !
Pourquoi Tôko mange une glace pilée ?
Ehi, ehi, ehi!
Calma aí, calma aí! Touko-senpai,
por que você tá comendo raspadinha?!
Эй-эй-эй! Токо,
почему ты ешь крошеный лёд?!
