Kurôzu-cho, a small fogbound town on the coast of Japan, is cursed. According to Shuichi Saito, the withdrawn boyfriend of teenager Kirie Goshima, their town is haunted not by a person or being but by a pattern: uzumaki, the spiral, the hypnotic secret shape of the world. It manifests itself in small ways: seashells, ferns, whirlpools in water, whirlwinds in air. And in large ways: the spiral marks on people's bodies, the insane obsessions of Shuichi's father, the voice from the cochlea in your inner ear. As the madness spreads, the inhabitants of Kurôzu-cho are pulled ever deeper, as if into a whirlpool from which there is no return...

This chapter focuses mostly on Battler's sister Ange, and her life twelve years after the massacre on Rokkenjima. The existence of magic is heavily implied in this chapter. Many new characters make their debut, such as Siesta 00, Gaap, and a number of humans. (Wikipedia)
