I Transmigrated into a Game with a Kindergarten Full of Max-Level Cursed Spirits

[This idea was recorded on August 8, 2023. If I change it again, I'm a dog.] A nurturing mobile game mysteriously appears on Nakahara Chiori's phone. [You have inherited a kindergarten. You are its principal.] [All the children here are oddballs. We hope you won't be prejudiced against them.] [Wash your hands before meals, take your nap on time, don't fight, and help one another...] [As the principal, please do your best to educate them, okay?] Looking at the pile of weirdly shaped children on her phone, she falls into thought. Nakahara Chiori: Is this some kind of monster kindergarten? Should I show my brother? Or go to the Detective Agency? But when she sees one of the little ones in the kindergarten crying its heart out, Nakahara Chiori's heart softens. Forget it. Sure, they're a bit ugly, but what could a kid have done wrong? I'll raise them. It's just a game, after all. There's no way they can actually get out... Oh. After raising them to max level, she somehow ends up inside the game. Facing this LV.100 kindergarten and surrounded by cries of "Teacher," "Master," "Mom," and "Principal," Nakahara Chiori: Stop calling me that, hey!!! She takes a deep breath. All right, first things first: I'll customize my face. At Tokyo Jujutsu High, Gojo Satoru and Geto Suguru receive a top-secret mission from the higher-ups. When they confidently head to that [kindergarten]... what they see leaves them speechless. "Good child." The woman before them, her eyes covered by white silk, is a stranger. Her lifeless hair is pale, and she cradles a Special Grade cursed spirit covered in eyes, softly humming a song. "Sleep now, sleep now... my precious little one..." The two young Special Grade sorcerers can't even tell whether she is human. She is the principal of this kindergarten. The cursed energy radiating from her is terrifying beyond measure. Not human among nonhumans, Special Grade among Special Grades. She is not a cursed spirit. She is an [unknown creature]. Notes: The heroine can customize her appearance however she likes, and her combat strength is a BUG. She is the strongest in the game, the sort of Level 100 final boss. Theme: Raising children in an unconventional way.
