Nikoru Yamana

She is the best friend of Runa Shirakawa. Nikoru has light-colored dyed hair that was lighter than Runa's, a necklace on the opening on her chest, piercings in the ears, flashy nails, and her fashion was that of a gal but she had sharp eyes that gave her the air of a Yankee(delinquent). Nikoru is a sinical and judgmental girl, specifically towards men, she refuses to trust any guy who dates Runa, however when she is with her friends she is jolly and friendly. but if a guy she hates looks at her she gives them a death glare. However deep down she is only trying to protect Runa from getting hurt and she is a good person.
