Olizumi is the femslash ship between Izumi Curtis and Olivier Mira Armstrong from the Fullmetal Alchemist fandom.

Canon
Even though Olivier didn't get the chance to meet Izumi when she spent a whole month in Briggs' mountains during winter, she was informed by her men that a mysterious woman knocked them out with easy and has been taking their food until she "disappeared" from the mountain. When Olivier informs the Elric Brothers of that particular month and the unidentified woman who over powered her men, they knew right away that she is talking about their Alchemy teacher but chosen to not inform the Major General of this. If Olivier wasn't sent to Central when Izumi returned to Briggs in order to deliver a message to her men about the Promise Day, there was a chance that they would have met a lot earlier.

On the day of the Promise Day, long before the eclipse began, Izumi lends Olivier's men her assistance while their Major General is fighting the Homunculus Sloth with her younger brother, Alex. After the Military foolishly unleased their uncontrolled dummies, that Olivier takes on as well as the Homunculus with a few soldiers by her side, Izumi arrives on the scene with Sig after taking out a hand full of dumps before she lends an injured Olivier a hand in her fight Sloth. Once Izumi saw Olivier she knew right away that she is the Major General that the House Wife Alchemist has heard about, and when Olivier asks Izumi who she is Izumi just smiles as she tells her that Briggs' men had asked her to lend them a hand. When Sloth charges in for another attack Olivier was stunned by Izumi as she only used her own hands and strength to flip the giant Homunculus over her shoulders and strait towards her husband as he punches Sloth to the ground. Once Sloth was defeated for good, Olivier thanks Izumi for her help and after she tells the female Armstrong that she is their teacher she realized who the House Wife Alchemist is right away. Izumi originally planed to help Briggs get a fern grip on Central before leaving to prevent the enemy from getting their hands on her, but once she hears Olivier and Alex say that they can't let the Elrics and their allies fight the battle alone, she decides to stay a bit longer to help Olivier.

After they catch the higher up they saved they had him confess their monstrous plans for the country to soldiers who weren't aware of it, which enraged both women who struck the man when he tries to justify their actions and reasons for them. Izumi then tells the men to believe in themselves, in which gave Olivier a few more allies in the battle. Afterwards they found a door that reveals a secret staircase that they all walk down on to see where it leads, the anime has Olivier and Izumi talk about the bonds that people share with one another and how the loss of a loved one could drive one to take much measures to bring them back. Because Olivier is a solider of high rank she couldn't let herself be grief stricken over such things, even though the death of her Caption got her to understand what Izumi might had went through when she lost her only baby. When they were half way down the staircase Izumi states that it is time for them to part ways, and before Izumi begins to make her escape tunnel she and Olivier shake hands as Olivier tells Izumi that it has been an honor to fight along side her. Before they knew what was happening, Izumi gets pulled into a large eyeball on the ground that shocks Olivier and continues to walk down the staircase in hopes that they'll be able to find her.

Olivier was able to "find" Izumi when she was chasing after Father, but stopped when got to the level that Olivier and their allies are on. After Izumi drops Roy Mustang with them, Olivier watches Izumi continuing her pursuit of Father and wanted to go back into the fight, but was convinced to stand down while Alex goes to help Izumi in her place.

Fanon
Even though the two had only met once in the final arc of Fullmetal Alchemist, fans were able that Izumi and Olivier did get a chance to meet since they are very much like in strength, have a connection with the Elric brothers and strong, large men, Izumi's husband and Olivier's younger brother, and have short tempers that terrifies people who anger or dares to cross them.
