Amano Kaguya

Amano Kaguya (天埜郭夜) is a middle school girl who resides aboard the Hikoboshi II. Like Kumokawa Seria, she is one of the 'abominable brains’ associated with Academy City's Board of Directors, with her unnamed director specializing in the aerospace industry.

Etymology
Kaguya's name is derived from the character Kaguya-hime from said to be one of the oldest Japanese legends in written record.

Appearance
Amano Kaguya is described as a middle school with anachronistic long black hair and a junihitoe which adds to her resemblance to the folktale figure. She is said to possesses inhuman beauty, however the balance and position of her face and body parts appear wrong, with a shoujou manga figure which should not be possible. This is due to being confined in space for a long time.

Background
At some point in the past, Amano Kaguya was launched into space and confined in the Zero Gravity Biological Impact Laboratory section of the Hikoboshi II, staying there ever since. Her long stay in space resulted in her beauty and abnormal figure, as well as leaving her no longer able to eat or walk on her own two feet in the 1G environment of Earth.

Lance of Gungnir Arc
After the events at Sargasso, Amano Kaguya receives orders from Kihara Yuiitsu to use the S5 against Kamijou Touma and Othinus. As she deploys the system, she communicates with Kumokawa Seria.

Later she is one of the people watching when Touma fought with Thor and then stops Othinus' attempt at suicide.
