This is the "Boss Battle!" featured on Apple's channel. I've filled in the story gaps based on my own interpretation.
About
The Holy Empire is a world that has met its end due to the clashing ideals of Yelli, Lucia, and Atlari. Despite being destroyed, the kingdom remains eerily clean. No living beings exist in this kingdom other than the characters listed below. Story: There was once a human child cared for by the angel Atlari. Humans, fearing the angel as a monster, killed the child. Decades have passed since then. Locations Outskirts of the Holy Empire: A maze-like area where angels reside. Hive: A massive beehive located in various spots within the outskirts. Holy Empire: The main, grand empire. It seems only females inhabit this place. Important: This is a healing-focused story. If you die, you will respawn at the last bench where you rested.
