 Yuko survives this confrontation.In the novel, her alcoholic and abusive father died in the hands of a yakuza, which led her family to be able to live in peace, but the abuse still left Yuko nightmares, and left her terrified of gore and violence.In the manga, it is clear that Yuko has an extremely high paranoia level (Shuya pointed out that she was crying when everyone awakened on the island).
