Someone was asking about a show where the main character shows up at school & has to battle one of the strongest people there. Many of us tried to give suggestions, but kept getting thrown off because the protagonist had light brown hair. I kicked myself because I knew the show but couldn't remember the name of it.... Maken-Ki. I should have fired up my laptop sooner, the cat girl pics are background screens on it named.... Maken-ki1 & 2. Hope this helps whoever it was that was asking.
