An adult version of Gokou Hinata that only appears in Oreimo Tsuzuku's Kuroneko ending. There's only one image of her, and it's from PSP, so the quality was questionable, but I think it worked out alright. I loved her upgrading from a cheeky kid to a cool aunt, reminded me of Nae in Robotics;Notes.
Gokou Hinata: Hinata, brown hair, blunt bangs, medium hair, low ponytail, brown eyes, small breasts
