The mirror universe is the informal name for our parallel universe. This parallel universe coexists with the prime universe on another dimensional plane. The mirror universe was so named because many people and places seemed to be opposites of their characteristics in the prime universe, with numerous "good" aspects now "evil" and vice versa, thus "mirror-like."
The mirror universe appears only in Expanded Universe of Planetes, but in Anime can see the "bad" Hachirota "Hachimaki" Hoshino and the "bad" Ai Tanabe. The first appearance in Expanded Universe is in the second part of Planetes Mata 2 (episode "Mirror Universe"), where the ship FEF 05 enters a vortex and goes to the mirror universe, showing a 'bad version' of Josep Maria #, İhi Kadse and Laia (who is killed).
After appeared in several episodes of Planetes 3rd. Josep Maria # from mirror universe is the head of the Teremedovulcan Union. It also appears Carol, a girl who didn't appear their "good part" of our world, she joins the ship FEF 07 and is a traitor. Then appears a mirror universe's girl called Over-Intendent Selena, seeking a good relationship with his double, but she hijacked ship 07 with Carol and wishes to use as a weapon of a war in his world. Josep Maria 15 found the same Over-Intendent with fewer years and sees an opportunity: if he erases her memory Selena won't grow and never will exist the Superintendent or his entire war that nearly ended with all teremedosians in the mirror universe: a war between Teremedovulcan Union and an Alliance of Terrans (humans) and Klingons. After mirror universe appeared in another episode, where Josep Maria 15 gets to know that in altered mirror universe he is famous because there had been "great achievement", although he has never done anything important there.
In mirror universe in "schools" the students are evaluated in pairs instead of individually as in our world, causing major problems between the pairs formed (same sex or different sex).
