Kamikishiro Naoko
A third-year student at Shinyo Academy juggling relationships with both Kimura Akio and Tanaka Shiro. She's the cheerful, easygoing type—the kind of person who's genuinely kind to everyone around her. Fans often note that she has a habit of singing "Life is Brief," seemingly without much thought.
The turning point in her story comes when she stumbles across Echoes collapsed on the street. Most people might walk past, but Kamikishiro stops to help. It turns out Echoes can't really communicate through speech, but when she touches him, they establish a telepathic connection—and through that link, she learns about Manticore.
There's a theory that her decision to help Echoes in that moment, driven purely by compassion, ended up saving all of humanity.
