In heaven and earth, gods, demons, and humans live in three realms.
God is ruthless.
Demon, heartless.
Only humans have seven emotions and six desires, so humans are the weakest and belong to the lower realm.
The three realms do not communicate with each other.
Gods are merciless, and demons are heartless. However, fate manipulates people, and a man with a heart is born in the demon world. He has a heart, but is heartless. Gods and demons combine to dominate the three realms.
Its name is unpretentious.
