Suimitsutou (Older Sister, Anime Only)

Kyouchikytou (夾竹桃 Kyouchikutou?) is a female assassin from the organisation IU. Along with Jeanne d'Arc, she was smuggled into Tokyo Butei High School with Mine Riko's help. Her real identity is Momoko Suzuki (鈴木桃子 Suzuki Momoko?).


Much like Riko, she has a rather short stature and often dresses in gothic lolita fashion. She has purple eyes and has long, black hair and her bangs are trimmed neatly.


Kyou is very reserved and quiet. She is a genius tactician and knows how to cover her tracks. In one instance she sent an entire work complex crumbling down on Akari and her friends with a very intricate Rude Golberg Machine that, in the end, could only be ruled as a freak accident due to the nature of the sabatoge. Despite this, she is very fond of otaku culture and lolita fashion.

She is also a major fan of yuri, often times blushing or fawning over how Urara and Akari interact with each other. On a few occasions, she has been seen to write down what they are doing and has even gone as far as to write erotic fiction about them.


Kyou along with Riko and other members of IU led an offensive against the Mamiya Family's estate. The offensive was successful, as it resulted in the deaths of many members and forced the survivors to scatter. As Akari and Nonoka were fleeing, however, Kyou captured the sisters. She would let them go but not without poisoning Nonoka. Two years later Kyou, along with Riko, would eventually track down two of the sisters Tokyo Butei High. She worked from the shadows, making threats on Akari's life be it an "accident" or run in with thugs.

However, she finally stepped out of the shadows following Riko springing into action and confronted Akari directly. After the latter's refusal to give up the poison she so desperately sought, she taunted Akari by reminding her the severity of Nonoka's diminishing health and left her a card to her hotel suite. Akari and her friends would raid her hotel suite, but they would ultimately fail capturing her there. After defeating most of Akari's friends, she and Akari clashed on a bridge over Tokyo bay. Kyou, however, would ultimately lose the fight as Akari finally revealed her family's secret technique which, to her surprise, was not a poison.

Following her defeat at the hands of Aria and Akari, she cured Nonoka and takes a plea bargain for the sake of attending an upcoming Summer Comiket. So she enrolls in Butei high (despite being a college graduate) as a part of her plea bargain.


  • Despite her young shortness, she is actually 24 and an alumni of Tokyo University's Graduate School of Pharmaceutical Sciences.
  • Like for fellow and former IU accomplice, Mine Riko, she is an otaku going to doujinshi conventions under her pen-name Christine Momoko (クリスチーネ桃子?)
  • The Hidan no Aria AA anime gives her an older sister named Suimitsutou (voiced by Michelle Rojas in the English Dub).
