This is a wonderful world, the world is like two sides of a coin.
——Light is the paradise of human beings, and darkness is the world of monsters.
There is a kind of person who is born with strength.
- Summon weapons. They are the only ones who can fight against monsters.
They (she) gathered together and established the organization "Death", and the leader was known as the "Death Queen"
——The mask he wears when moving, the raised corners of his mouth seem to be ridiculing, and the downward curve seems to be compassion.
In this world where humans and demons coexist, she is the Queen!
