I don't understand this setting.
So it's a medieval fantasy setting......except they have cars and cellphones.
There are knights.....except they're not actually knights they're just bodyguards of corporations larping as knights.
Half the cast are dressed in fantasy clothes, the rest are dressed in modern clothing
The Tyrant came from 1000 years ago and seems confused with modern tech (she was even found dressed in fantasy garb)......except you find she had a modern android cellphone in her bank she left before getting sealed away and somehow it's more advanced than what people in this setting are using now (everyone in present day in-universe are usual really old-style fliphones)
WHAT THE FUCK IS THIS FUCKING SETTING I CANNOT GET IMMERSED AT ALL IT DOESN'T MAKE ANY FUCKING SENSE THERE'S ZERO CONSISTENCY WHATSOEVER. At least Blue Archive is fucking consistent with it's setting. This game's worldbuilding is a fucking mess.
