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...
The mucin is nice and slimy!
الموسين زلق حقّاً
Hach, ihr Muzin ist so herrlich glitschig …
Vaya, las mucinas
las hacen muy resbalosas, ¿eh?
Vaya, son muy resbaladizas, ¿eh?
C’est les mucines
qui les rendent visqueux.
Wow, la mucina è bella viscida.
Mucinas são pegajosas
que é uma beleza.
Муцин такой приятный и вязкий.
