More than 150 years ago, because of the powerful power of the Immortals, the government was afraid of overthrowing their regime and posing a threat to them, so they massacred the Immortals in large numbers. With the "extinction" of immortal species, people slowly relaxed their vigilance. And that catastrophe was called "Lady Tears", or "Lady-tears". But people don't know that with the demise of the immortal species, more undercurrents are gradually emerging. Those powers, monsters, demons, witches, assassins, fanatics, cyborgs, mutants... Are eroding the world bit by bit.
150 Years later, the demon sealed in the coffin awakened, and the person who awakened him was a count who killed his father and committed the crime of king. They have similar ambitions and similar goals, and they want to paint this deep night with bright red.
The assassin with golden eyes, the madman with red hair, the angel with blue shadow, the gloomy nun, the taciturn tombkeeper, the bard with some BT, the genius science girl... They will all gather here...
