Hidan no Aria AA Episode 11 English Subbed Episode Title:Showdown.Episode Description:Kyochikutou sets her sights on taking out all of Akari's friends, starting off by subduing Hina with an acidic poison gas. She next comes up against Raika, hitting her with a paralysing poison, before confronting Urara and hitting her with a hallucigenic gas. Akari attempts to distract Kyochikutou so that Shino can launch a surprise attack, but Kyochikutou brings out a gatling gun, with Shino taking heavy damage from protecting Akari. Angered, Akari prepares to use the Takamakuri technique, which isn't a poison but instead uses electrodes to create a gyro-like attack, using what she learned from Aria to stay safe and destroys Kyochikutou's gun. As Kyochikutou is taken into custody, Aria informs Akari that another I-U agent is present, at which point Kyochikutou's older sister, Suimitsutou, attacks with a giant mecha.
