Autumn (オータム) is a member of Phantom Task who fought with Ichika Orimura during the IS Academy's anniversary. She also revealed to Ichika that the ones responsible for his kidnapping during the 2nd Mondo Grosso was the Phantom task, to only then taunt him on the reunion with them.


Autumn is a rash, hot headed, arrogant, sadistic psychopath. She is a least capable of restraining herself when she has to or is order to by Squall. She can even put on an act as a professional saleswoman when she first approach Ichika, to which shows her manipulation.


Autumn is introduced under the disguise Makagami Ayako, one of many IS expansion saleswomen trying to get Ichika to buy some expansion sets. She later appears to hide Ichika from the masses of girls chasing after him, and reveals her true identity and purpose. Autumn almost succeeded in stealing Byakushiki with a device called the 'Remover', only to fail at the last minute when Tatenashi Sarashiki interfered. She blamed M for the failure, as the latter was responsible for both the creation of the 'Remover' and the plan to attack during the IS Academy's anniversary. She was hinted to have a homosexual relationship with Squall Meusel, uncharacteristically blushing like a little girl upon seeing Squall.

Infinite Stratos & AbilitesEdit

She pilots an IS called Arachne, a eight-legged 2nd generation IS that was stolen from the USA. She is skilled enough with it to overpower Ichika but was easily bested by Tatenashi afterwards.
