Akira Tachibana

Akira Tachibana is the biological father of protagonist Hibiki, a man who vanished from his family's life a decade ago, unable to cope with the immense public scrutiny that followed his daughter's miraculous survival. When he reappears in Season 3, he masks his deep-seated guilt and cowardice behind a breezy, nonchalant demeanor while drifting through temporary work. However, when a looming threat puts Hibiki in danger, his long-suppressed paternal instincts surge to the surface, driving him to stand firm and protect her. This pivotal moment sets him on a path toward atonement, ultimately leading to a heartfelt reconciliation and the reclaiming of his role as her father.
