Leone Halcon, A knight from ***** kingdom who came from another world (isekai).
Her duty as a spy and overseeing the border area, one day when Leone was on an expedition around the kingdom's borders suddenly a blinding light interfered with her vision and instantly Leone had entered another world. Someone she met for the first time said :

"Welcome to Earth, we are short of people so I summon you, join here. After all, you will not survive in this world alone." 

Being trapped in a foreign world with no knowledge forced Leone to follow that person's words but Leone didn't like that person. That person turned out to be Manager-san, who turned Leone into a VTuber.
