Yuusha Party kara Tsuihou sareta kedo, EX Skill "Kotei Damage" de Muteki no Sonzai ni Natta

Chrome was part of a hero's party as a magician, believing he shared strong bonds with Irina, who promised to marry him, and Yuno, the hero and his friend. In reality, Irina had grown close to Yuno, and Chrome was used to enhance the hero's strength before being discarded. Stripped of his magic and expelled from the group, he faced death at the hands of demons. In that moment of desperation, he tapped into an inner "darkness" and gained a powerful, unique skill. With this newfound ability, he sought vengeance.
