Synopsis

In 1986, Yuri and Otoya grapple with the unsettling mystery of a cursed violin, one that seems to summon a monstrous presence targeting its owners. Meanwhile, Wataru seeks the counsel of a luthier, striving to craft an instrument that truly reflects his own essence. Across both time periods, whispers of the IXA System consistently coincide with the emergence of a new Rider on the battlefield.
