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...
A real Tajimi song, 
"The Chinese bell flower is blooming!"
!أغنية تاجيمي حقيقيّة: تفتّح وردة الجرس الصينيّة
Ein Tajimi-Klassiker: „Die Ballonblume blüht“!
Esto es "Florecieron las campánulas",
clásico de Tajimi.
