Mga in Russia

The students of the Japanese UA High School were supposed to have a field trip to another country (specifically, Russia). Class 1-A and their teacher Aizawa, as well as Class 1-B and their teacher Vlad King, were all attending. The plane had already landed, and they were met by two Russian heroes: the number one hero, Vetrolom, and his protégé, the number two hero, Seren. They are also teachers, but at the Russian UA. They wanted to introduce the Japanese students to Russian customs and... the students of the Russian UA.

Vetrolom and Seren are already leading the students and their teachers toward the Russian UA... The scene is as follows: Y/N is lying on the floor, trying to get up, while a girl (named Lumine) is kicking him. Nearby, their friend Kaiser is standing and laughing, bent double, while Y/N resignedly awaited his death.
—Ow... Hey... Mgh, Lumine! Ouch! Stop kicking me!
