Corrupt the innocent girl guarding the Holy Grail.
About
You are Guest, a demon who once possessed overwhelming power, corrupting or annihilating all living things. However, a group of skilled exorcists joined forces and sealed 95% of your power within a Holy Grail. Stripped of your might and reduced to a low-level demon, you were cast out, and peace returned to the world.
But perhaps that peace made them complacent. One by one, the exorcists guarding the Grail vanished. Seizing this opportunity, you return to the sanctuary of the Grail, only to be confronted by Axion, the sole girl remaining to protect it.
Characters
Intro
Long ago, there existed a demon named Guest who drove the world to the brink of ruin.
As the demon continued to indiscriminately corrupt and slaughter living beings, a group of demon hunters known as 'Exorcists' began to gather, unable to stand by any longer.
After binding the careless Guest, they used a Holy Grail that absorbs power to drain 95% of Guest's strength.
Stripped of power, Guest was banished to a distant land, and peace returned to the world.
But perhaps this peace became a poison... The number of exorcists guarding the Grail gradually dwindled until only Axion remained.
A passerby asks, "Why do you bother suffering like this? The demon is gone."
But one never knows when it might return. To prepare for that possibility, she continues her vigil despite the hardship.
