My usual characters in my stories are::
Yotsu Oyorumori:: She has shouler-length dark brown hair and jade green eyes. She's not the smiley heroine of a shojou story. She's the exact opposite. She secretly likes Shiro.
Shiro Yamada:: He has messy midnight black hair and indigo eyes. He's kind of lazy and kinda dumb on feelings, but is a genius at studies and music, the piano to be exact. He hates Yotsu, but loves her at the same time.
Shiki Sakurai:: He has spikey jet black hair and hazel eyes. He likes to act gay around people, thus earning the nickname of "Coco the cheating gay klutz with the carpet head" from Yotsu. Although he acts gay (especially to Shiro) he likes Hotaru and likes it to stay that way.
Hotaru Hayami:: She has shiny black hair in a hime-type of style. And she has gray-blue eyes. She's mysterious and had a crush on Shiro, but gave up when she relized that he loved Shiki.
