“我们一起离开这个小镇吧。” 斋藤秀一对他的老同学五岛桐绘说道。桐绘是从小在黑涡镇长大的女高中生。而如今，小镇的一切都在变得诡异：离奇的旋风，火葬场里翻腾的浓烟，甚至镇上的居民都开始变为漩涡。人们眼球开始旋转，舌头卷成螺旋形，身体也扭曲成了无法理解的形状。为了逃离漩涡的诅咒，桐绘决心逃离黑涡镇，但她真的能彻底摆脱从这场混乱吗？ “Let’s leave this town together,” asks Shuichi Saito, a former classmate of Kirie Goshima, a high school girl who was born and grew up in Kurouzu-cho. Everything from a strange whirlwind, billowing smoke from the crematorium, and the residents is turning into spirals. People’s eyes spin in whirls, a tongue spirals, and the bodies twist unnaturally. In an attempt to escape the curse of the spirals, Kirie decides to flee from Kurouzu-cho, but can she get away from this turmoil?
