Kizuna Kazayama

Kizuna Kazayama is the Hunting Tool Hero summoned from another realm, standing as one of the Four Holy Heroes within the 'Kizuna World'. She spent years trapped inside the 'Infinite Labyrinth' before being rescued by Naofumi, forging a close bond of friendship with him. Bright-spirited and full of zest for life, Kizuna wields a powerful legendary weapon that carries a unique limitation: it cannot harm human beings. She firmly opposes the idea of heroes from different worlds slaughtering one another for survival, and she dedicates herself to finding a path of coexistence.
