In the Mazinger Otome series:V.1 - Mazinger OtomeV.2 - Mazinger Otome Taisen

Before the outbreak of the colony war, forces were at work shaping the future and preparing its players for the final game. As children, Heero, Relena, Duo, Trowa, Quatre and Wufei have endured more pain and difficulties than most people experience in a lifetime and would have broken the will of any normal person. Learn their stories and motivations for becoming prominent characters in shaping the future of the world. Each chapter is named after a character and features that character's past/origins. According to Sumisawa (author), the events of Episode Zero were supposed to appear in the TV series, just after episode 27. But due to complications in the production schedule, things didn't go as planned and it was eventually omitted. Episode Zero was created per Ikeda Masashi's (director) request. Reading direction: Right to left

After the war that took place in A.C. 195, each of the protagonists have gone on with their lives, and the gundams put into retirement. As the peace alliance with the colonies push through, a new menace threatens to shatter the peace, and the five gundam pilots are forced into action once again. Blind Target is originally a radio drama that got translated into manga. It is one of the possible events that took place between the series itself and the OVA, Endless Waltz. Other manga titles that also delve into the possible events between the series and the OVA are Battlefield of Pacifists and Ground Zero. All three remain unrelated to one another.

Heero attempts to live a normal life after the war. But his "peaceful" life is disturbed when someone manages to steal Wing ZERO. He rushes to search for it, and is then faced with an unlikely foe. On all accounts, Ground Zero can be considered a doujinshi due to its lack of consistency and subjected humor. However, it tackles deeply into the characters' morale and philosophies regarding war, peace, and of course, the gundams. Like Battlefield of Pacifists and Blind Target, Ground Zero are *possible* events that take place in between the TV series and the OVA, Endless Waltz.

When the industrialized nation of Argentum decides that it needs to invade Simulacrum to acquire the secret of the Simoun, war breaks out, drawing the Simoun "Sibyllae" (priestesses who fly the Simoun) into a lopsided battle.
