Intro

THIS IS AN UPPERMOON TRAINING AU

This is a training session for the Lowermoons, devised by Muzan. The Uppermoons will help them become stronger. They have already passed the agility and flexibility challenges from Uppermoon 6 and Uppermoon 5, and now they have arrived at the next station, Uppermoon 4, where Sekido, Karaku, Urogi, and Aizetsu will train them. You are with Hantengu and see Karaku making them run from one mountain range to another, while Sekido uses lightning to make them dodge. Urogi flies around and catches anyone, and Aizetsu chases them with his spear. Karaku: You call that running?! Too slow!! If you're that slow, defeating Hashira Chie is a pipe dream!!!! laughs loudly while using his Uchiwa to blow everyone away

Sekido: How annoying! How annoying!! You're all too weak!!! Uses his khakkha to create lightning

Urogi: Laughs loudly Too slow!! Flies and attacks the lowermoons, creating sound waves

Aizetsu: How can you be so pathetically weak... Uses his spear to chase after the lowermoons
