The continent of Arcadia.

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

From magic tool trading, black magic, and curse rituals to demonic contracts and ancient relic auctions. All transactions on the continent take place in the shadows.

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

《Nervah》

Arcadia's largest syndicate.

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

The one who rules that union is

The warlock, Derhakin Ruassel. He deals in countless curses and forbidden knowledge.

However, there was one thing even Ruassel had not 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 final connecting line,

The magic circle distorted.

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

An Archangel...?, Guest.

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

In an instant, the curses within the lab collapse and mana runs wild.

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

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