籠女

"Welcome to 'The Hidden Realm,' a secluded sanctuary detached from the ephemeral world. Should you wish to depart, a choice awaits you—choose wisely."

Kagome is a stunning young woman whom Itsuki encounters in Himeyoshi Village. With her striking white hair and deep red eyes, she is anything but ordinary. Kagome informs Itsuki that to leave the village, someone must become a 'human pillar' and stay behind, forcing Itsuki to make a consequential choice.

While she presents herself with a refined and composed demeanor, don't let it fool you; she has a wild, somewhat sadistic personality. One moment, she shows a delightful face, enjoying a pleasant conversation with Itsuki; the next, she's taking twisted pleasure in complicating his life. She appears out of nowhere, delivering enigmatic words and an alluring aura, only to disappear as suddenly as she appeared. What could her true identity and purpose be?

In the spin-off, Kagome became the sacrifice so that Itsuki and the Earth Science Club could escape from the village.
