A rift born at the intersection of existence and the endless desires of humanity. Demon Possession is not a mere avatar, but a token of an eternal contract with the beings of the abyss. It is a pact in itself, where those who crave power accept demonic power and, in return, bear the mark of the demon upon their bodies.

The moment this rift is accepted into the body, the user's body is no longer ordinary. The demonic power seething within them is unleashed, and a solid horn sprouts from their head. This symbolizes a steadfast will unwavering against any temptation, while also signaling to the world that the demonic presence is with them.

The purple energy flowing through his body awakens latent powers, unleashing powerful abilities normally inaccessible. This energy goes beyond simply amplifying combat prowess; it instills fear and confusion in all enemies, becoming an overwhelming force that dominates the battlefield.

Demon Possession is both a source of power and a dangerous entity. If the user fails to fully control this power, they will gradually be consumed by the demon, potentially losing everything they possess. Only those who can master the demonic power with a strong will can truly wield this contract.
