Hida Nayuta
Gender: Female
Hair Color: Black
Hida Nayuta is best known as the inventor of the Heart Hybrid Gear technology—a breakthrough that changed everything, at least until she mysteriously disappeared. She's the mother of Kizuna and Reiri, and was once Aine's guardian.
A striking woman with long black hair and dark blue eyes, Nayuta has an appearance that's often compared to her daughter's, though her hair is noticeably straighter and darker. She's charming in that disarming way brilliant people sometimes are.
The thing is, Nayuta is driven by pure curiosity—the kind that doesn't care much about ethics or consequences. She studies whatever interests her, using whatever methods work, and that obsessive approach created serious friction with her kids. She eventually abandoned both Kizuna and Reiri when they no longer served her research purposes. In a moment of rare honesty, she admitted she'd only had children in the first place to see if anything would change about herself as a person.
Her most significant work was developing the Heart Hybrid Gear and implanting it in Kizuna, making him the first person ever to use the technology. Beyond that, the details of her disappearance remain unclear—another mystery that keeps fans speculating about what really happened to her.
