Yuko Sakaki

Girl #9 Yuko Sakaki is a troubled girl with big ears, who witnesses Oki's accidental death and blames Shuuya for it. Later, she joins up with several other girls and hides in an abandoned lighthouse. When the girls find Shuya and bring him in, she poisons his food. The food, however, is instead eaten by Yuka Nakagawa, who quickly dies. The girls soon turn on each other and kill each other in a violent gun fight. Yuko survives this confrontation. In the novel and manga, Yuko runs from Shuya. When she gets to the top of the lighthouse, her foot slips, and she falls. Shuya catches her and tries to pull her up, despite his severe injuries. Yuko realizes that Shuya is responsible for saving her life, even though he suffers agonizing pain, and this leads her to realise that he is good after all; her friends died in vain. Yuko pries her hand free from the bars, and falls to her death. Yuko dies thirty-third in the manga. (Source: Wikipedia)
