Kurayashiki Kazuha

The president of Kurayashiki Industry.
Kazuha is a lonely genius engineer who has the power to influence the very existence of Hope Town. She's also Kizuna's benefactor since they are somehow "blood-related."

Although she's closing in on her 30s, she remains unconcerned about her age. Her youthful looks often lead people to believe she's as young as Kizuna. She's not easy to deal with—aside from her brilliant mind, she's known for her sharp tongue and uncompromising egoism. The only person she might be slightly open with is Hidetaka, excluding her android, Yuuki.

Yamato officials are particularly interested in Kazuha. They use various methods to get her to their side, such as threatening her by force or offering her a distinctive upper-class position. Nonetheless, she rejects them all.

"While I'm not against using force, being involved in it is a hassle."
