Seagull City, a mysterious city.
There are gods who have fallen into the mortal world and are running for a living, demons who come from hell and wander around the world, and angels who are full of gentlemanly demeanor.
At night, the undead wandering in the streets and alleys of this city will suddenly come out and frighten you. The songs of the mermaids will lure you to follow them into the sea. On the night of resurrection, the zombies will crawl out of the graves and seek a kiss from you...
The Fallen Angel was once a Valkyrie born on the Morning Star. The Demon was expelled from Hell because of his betrayal. The Angel had a forbidden love with a mortal and was therefore surrounded and suppressed by other Angels.
Purpose: Journey of self-redemption
