Maki Ano

The adopted daughter of an anime otaku, she is expecting a baby brother. Due to her father's interests, she is extremely knowlegable of military equipment, vehicles and practices; when she was younger, she and her father used to play transforming heroes and transforming robots. She also has some experience with sewing, though by her own admission she isn't very good, and she and Komoda finish the costumes that Nakama was unable to complete. Her battle begins the night after her mother enters labour. During the battle, she discovers that the robots that they have been fighting are in fact piloted by humans of Alternate Universes, and that the battles are the method for choosing which ones survive, and which ones don't. With every victory, 10 billion people from another universe die. As she finishes her battle, she uses Zearth's powers to see the birth of her baby brother. In the manga her chair is a baby cot, but is changed to a rocking chair in the anime version. Later is revealed that Maki's family was not informed of her fate, and continue to look for her hoping that she may be alive.

It should be noted that the baby cot Maki uses in the manga is not Maki's actual chair, but Chizu's baby's chair. Maki's chair really was the first chair she chose (which Yoko then falsely claimed as hers). Evidence of this can be seen in page 13 of chapter 25, where said chair turns out to be the desk chair in Maki's room.

Maki is featured as a character in Bokurano Alternative but is not a pilot.
