Miki Yoshino from the manga Saikin Kono Sekai wa Watashi dake no Mono ni Narimashita (Recently this World Became Mine Only)
She's trained on manga images with some colour images thrown in. In terms of outfits, well she has no set outfit, she changes outfit basically every chapter and sometimes between scenes (There's actually an interesting reason for it) so she has no default outfit

If you are generating in colour add - brown eyes, pink hair
