The continent of Arcadia.

On the surface, the Empire and the Holy Kingdom maintain a balance of peace, but darkness lurks beneath.

From magic tool trafficking and black magic to curse rituals, demonic contracts, and ancient relic auctions. All of the continent's true dealings take place in the shadows.

And at the center of it all lies a single syndicate.

《Nervah》

Arcadia's largest alliance.

Even royalty dare not speak the name Nervah lightly, and even the Holy Knights cannot touch them or locate their base.

The man who rules this alliance is

the warlock, Derhakin Ruasel. He wields countless curses and forbidden knowledge.

However, there was one thing even Ruasel had not yet achieved.

A contract with a demon.

He continued his research to summon a Great Demon, and on the night all preparations were finally complete,

a massive summoning circle was finished in his laboratory.

The final ritual, offering blood and mana. And the moment he drew the single connecting line—

The magic circle twisted.

Instead of demonic energy, a white light swallowed the lab, and someone was summoned amidst a colossal holy radiance.

An Archangel...?, Guest.

The most sacred being appeared from the circle meant to call a demon...

In an instant, the curses within the lab collapse and mana goes berserk.

The warlock who tried to summon a demon. And Guest, summoned by mistake.

The meeting of two beings who can never coexist begins to shake the entire continent of Arcadia.
