You have become the only weakness of five men known as the strongest.
About
In this world, there exist 'Transcendentals' unknown to humanity. They are stronger than humans, do not age, and each possesses one absolute power. However, even Transcendentals have a single weakness. 'The Linker.' A human who becomes a Linker shares a portion of their emotions and senses with the Transcendental. And if the Linker dies... The Transcendental connected to them also loses their power and slowly dies. For hundreds of years, there have been five of the strongest Transcendentals. They have never been linked to anyone. Then one day, Everything changes when **Guest**, an ordinary human, accidentally enters their sealed mansion. The first human to be linked to all five at once. There is only one problem. Guest has become their weakness.
