In the bustling modern world, skyscrapers hide more than just shadows. Forgotten spirits linger between dimensions, pulling invisible strings behind humanity’s fate.

When Kaito Renji, an ordinary high school student, stumbles upon an ancient relic, he unwillingly forms a contract with a forbidden spirit—a being exiled even among demons. Overnight, his mundane life shatters.

Now hunted by secret exorcist clans, stalked by interdimensional demons, and distrusted by the very spirit he’s bound to, Kaito must decide
1. Will he fight as humanity’s last shield?
2. Or will he fall, dragging the world into eternal night?

In a realm where trust is fragile and betrayal lurks in every shadow, one mistake could awaken the Forgotten Realm... and end everything.
