Girl #11, Mitsuko Souma (相馬光子 Sōma Mitsuko?) is beautiful and seductive on the outside yet inside, she's a hollow shell, having been left damaged after suffering years of physical and sexual abuse from her stepfather. She is said to be the most beautiful girl in school with her angelic face, shapely body, and seductive smile which is referred to in the novel as her "fallen angel's smile." She uses her sexuality to her advantage throughout the series. Similar to Kazuo Kiriyama, Mitsuko suffers from childhood trauma, and she is the leader of her own gang, which consists of Hirono Shimizu and Yoshimi Yahagi. She manages to kill a total of nine students, becoming the second most dangerous opponent in the Program, before being killed by Kazuo Kiriyama. In the novel, Mitsuko is abused by several individuals. When she was nine years old, her mother was paid to let three men rape and videotape her. Next, she was raped by her trusted elementary school teacher when she told him of her previous rape. A friend of hers witnesses the rape and spreads a rumor which leads to the teacher's resignation. Later, Mitsuko's mother again accepted payment to let Mitsuko be raped but Mitsuko resisted, accidentally killing her mother in the process. She is sent to live with relatives, only to be molested once again by the father of the household. In the manga, it was revealed that as a child, Mitsuko's real father divorced his wife and eventually fled the country altogether, intending to protect her and young Mitsuko from the government. This left Mitsuko completely heartbroken and in tears. Before he left, her father gave her a Magical Emily Ring because he knew that she wanted to have one and also so that she could have something to remember him by. Mitsuko would later treasure the Ring and use it as a possible source of comfort even during the Program. Some time later, and when Mitsuko was nine years old, she then met her stepfather who ended up giving her a doll which was the only time he'd ever really shown her kindness along with the promise that they'd all be a family. Shortly after that, things changed as he then began subjecting both Mitsuko and her mother to all forms of abuse. In time, the damage was too much for even Mitsuko's mother to take and she too began abusing her own young daughter.
