Bougainvillea (Boo)

An elite agent of the ICP's Central Public Security division, she is sent to deal with Itsuki's attempts to independently investigate the issue of the brain-colony. She has a rather childish personality. She is nicknamed Bou by her partner Mintao. She pilots the Bougailian, which is a split form from the QT-ARMS known as Bouminder. Despite being an elite, she is afraid to see dead people or badly injured people, for example Elle Surre's case. Later they joined the Mystery Department when promised pizza every day. She considers being related to Kannagi as a curse as misfortune always befall them when pursuing Kannagi or even befriending her as in episode 19. She controls her QT-ARMs with her hands only. She and Min were so well integrated into the Mystery Department that they do not fear the headless ghost. However, when Kannagi approaches them in the dark with a torchlight, they screamed and ran away.
