It does not get much better than Kuroneko in her school sports outfit. Mashiro Yuki made just that. She cosplayed as Ruri Gokou from the popular anime series Ore no Imoto ga Konna ni Kawaii Wake ga Nai. Not only does she look truly adorable, her outfit also looks very well done and her eyes look simply gorgeous. On top of that, the photos look great, with lovely lightening to truly bring the best.
