シンジュ

A mystery girl who emerges from Shinju Town's ruins to confront Reiichi.
Mirror image of Haruna save for hair and eyes, she speaks as if she's known him forever.
She corners the trapped Reiichi with a chilling demand - procreate with Haruna and the others. But there's more to her game...

Shinju ensnares Reiichi with dark allure and mind-reader's insight, yet breaks character with jarring moments of childish behavior.
Her paradox: ruthlessly pushing Reiichi to violate Haruna and the others, while her own heart burns with barely hidden jealousy.

"Truth means nothing now. No one can ever leave this town."
