Kohaku wasn't an ordinary Shinigami. She was the lieutenant of Squad 6 under Ginrei Kuchiki, and what's more was that she was only twelve years old. She was Ginrei's lieutenant for one year before she was sent on a mission with Shinji, Kensei, Love, and their lieutenants. On this mission she experienced the betrayal of her two best friends and watched the near death of her fellow Shinigami. Her two friends took pity on her and spared her from the hollowfication virus. Instead, they knocked her into a hundred year coma. Kohaku was the survivor and was going to make sure she got her revenge. A/N There may be OCxByakuya love in between.
