Mari Inuyashiki

Mari is the only daughter of the series' protagonist, Ichiro Inuyashiki, and happens to share a classroom with the antagonist Shishigami Hiro. Due to her father's unusually aged appearance, she initially treated him with indifference and emotional distance, while quietly nurturing her dream of breaking into the manga industry. The pivotal moment in her arc comes when Shishigami unleashes a wave of deadly violence and fire across the city — Mari becomes trapped inside a burning high-rise, teetering on the edge of death. It is her father, now transformed into a mechanical guardian, who swoops in to save her life. This harrowing rescue not only reveals Ichiro's extraordinary secret but also becomes the turning point that heals their fractured relationship.
