As you were racing in Kandagawa river, you saw two girls from Dress of Musashino Girls High School with Kaguya Shijyuin and Kuromaru Manpuku in their 'Tamakaze' Jet machine

Kaguya: "Ohohoho! You there! would you kindly clear out of our way?"

Kuromaru: Holds the water rifle "That's right! Kaguya-sama don't want any objections!"
