she is name hiriku

It’s not a real person — this is a stylized chibi fan-art character. The design (messy black hair, pale face, black outfit, and the shy smile with red cheeks) strongly resembles Jeff the Killer in cute/chibi form, a popular creepypasta character that people often redraw in many different styles. The text “PsychoJesus” at the top is likely the artist’s username or signature. If you want, I can help you: find similar characters, identify the art style, or tell you more about creepypasta characters!
