Kuroneko of Oreimo

Ruri Gokō is one of the supporting characters of the Ore no Imouto ga Konna ni Kawaii Wake ga Nai light novel series and the female protagonist of the Ore no Kouhai ga Konna ni Kawaii Wake ga Nai manga series. She is an avid fan of the fantasy seinen series Maschera, and hates anime that focus on moe and cuteness to sell. Ruri is a member of the otaku group Otaku Girls Unite and is known as her handle name Kuroneko.

Kuroneko is 155 cm tall and weighs 43 kg. Her measurements are B77/W53/H80. She has long straight black hair neatly cut at the forehead in a hime-style, white skin, sleepy blue-grey eyes, and a birthmark under her left eye. She was described by Kyousuke as a ghost-like Japanese style beauty.

Ruri often acts according to the character she poses as (i.e., Queen of Nightmare): snobbish and overly confident of her own aptitude. However, she is in fact socially insecure, and is usually uncomfortable in talking to other people, particularly strangers. Fortunately, she eventually learns to make friends when she enrolls in high school once again.

Ruri came from a financially-challenged family, and with her parents often away, she is left to take care of her younger sisters, temporarily leaving behind her studies. Her costume, as proof of her skills in sewing, is completely done by hand, and she also occasionally uses her expertise in sewing to fix her sister's stuffed toys.

In an offline meeting of Otaku Girls Unite! in Akihabara, Ruri as Kuroneko attends as one of its participants. Like Kirino, a fellow participant, Ruri was not able to mingle with the other members of the group, although Ruri appears to be more uninterested to do so compared to Kirino, who had difficulty in engaging in prolonged conversation with the other members.

Even though she started off as haughty even toward Kyousuke and, despite the fact that Kyousuke at first seems to dislike her, eventually, they seem to get along. They share the same rationality, and seems equally appalled over some of Kirino's childish acts and likes.
