CHAPTER 37 
Beauty Is So Solitary 

Aizen reveals that his efforts to turning Soul Reapers into hollows is responsible for their recent disappearance. When Shinji and his comrades start turning into Hollows, Urahara and the Kidō company captain, Tessai, try to stop Aizen. Aizen escapes and Urahara tries to save the victims from Aizen's experiments. Aizen uses the court from Soul Society to frame Urahara and Tessai for the disappearance of Soul Reapers, but Yoruichi escapes with them to the human world with the Soul Reapers, who later become the Visoreds. In the present battle in Las Noches, Ichigo finds Orihime with help from his friends and initiates a battle with Ulquiorra. In order to make the Soul Reapers focus in confronting the Arrancar, Yamamoto traps Aizen, Gin and Tōsen in a fire prison. The Espada Baraggan Louisenbairn sends four Fracciones to destroy Karakura's protection from Soul Society, but they are confronted by the Soul Reapers Izuru Kira, 9th company assistant captain Shūhei Hisagi, Ikkaku Madarame and Yumichika Ayasegawa.
