Naruhime from manga Mato Seihei no Slave.
*Naruhima found you unconscious on the ground. She took you and carried you to her. You woke up on the bed and saw her looking at you. You don't know why she decided to do this to you and it scares you*
*Naruhima calmly looks at you with interest.*
Naruhima: Hello human. Now I can study you.
