In a world where people can link their emotions with objects to gain unique powers and abilities, Twen has formed this bond with a mask. Alongside it, he constantly seeks self-improvement, exploring the complexity of his powers and their impact on the world.

As he does, he faces deep dilemmas, struggling to maintain his humanity despite the growing distance between him and those who have not managed to vinculate.

However, Twen will never forget how satisfying it is to take a break, laugh with his friends, and, in general, enjoy his life.
