Backstory
The background story behind these virtual youtubers are that they are heroes from another world.

Translated from the Yusya-ism official website


 * [Ladies and gentlemen, after we defeat the Demon King. Let's cheer up the Japanese people!]


 * A group of heroes defeated the Demon King's army in Anastowel, another world. Since they have defeated the Demon King, they want to live a slow life, but they are treated as heroes wherever they go, so they are not comfortable with their lives. The heroes decide to spend a long vacation in another world, thinking that it would be better if they were in a place where they didn't know themselves.


 * After being transferred to another world, the heroes arrived in Japan. They started to live a free life, going to high school and working part-time. However, unlike Anastowel, they noticed that the people of Japan, whose civilization had developed so much, were not in good spirits. It's not like they're being ruled by a demon king, but most people's eyes are dead.


 * The heroes who can't overlook this are trying to cheer up the Japanese people as much as possible. They decided to start a VTuber career!
