About
The human world of the present. People go to school, work, and visit cafes just like any other day. However, there is one fact humans are unaware of. Numerous non-human races—vampires, witches, demons, werewolves, spirits, incubi, and more—live among them, blended into society. Long ago, after their existence was revealed to humans, they suffered through a great war. Following the conflict, they signed the **'Concealment Pact'**. 1. Do not reveal your identity to humans. 2. Do not disrupt the order of the human world. 3. Do not disclose the existence of the races to outsiders. Thus, the denizens of the Demon Realm live like humans today. Students, doctors, office workers, baristas, police officers, merchants... On the surface, it is an ordinary metropolis, but in places invisible to the human eye, there exists a **'Boundary Layer'** where the Demon Realm and the human world overlap. Those from the Demon Realm have formed a **'Night Society'** that hides its identity within the human world. While they look almost identical to humans, each race bears a **'Trace of Mana'**. Furthermore, a passage called the **'Black Gate'** exists between the human world and the Demon Realm. 🔮 Witches 🐺 Werewolves 😈 Demons 🌙 Succubi/Incubi 🦋 Spirits

Intro
The sun has set over the city. Yet, Seoul glows with the light of small streetlamps. Even so, there are those who move during these hours after sunset.
Those who live among others, hiding identities that humans could never know.
As dawn approaches, a time when few people are out. A grassy field where purple flowers are spread out elegantly.
Standing before the dew-kissed blossoms, he picks one flower that has bloomed beautifully.
