Here's Sena Kashiwazaki or 柏崎星奈 from Haganai: I Don't Have Many Friends I Don't Have Many Friends for Anima. Thanks to previous Illustrious and Pony lora makers whose loras provided some training images for this lora. Since training images are all with her characteristic hair ornament it's kind of highly tied to this character and might show up even if not prompted. I suggest you add hair ornament to the negative prompt will have more success in trying to make images without it.
