I don't own Fullmetal Alchemist or any of the characters. But this is my story on what would happen if Izumi met Scar. This is set right after we first meet Izumi in the anime.
Izumi You Got A Consumer!
Izumi sat behind the counter at the meat shop, she and Sig owned. Sig was in bed with the flu and couldn't run the store like he usually does. It had been two days since Edward, Alphonse, and Wirny left to look for the Ishbalans.
Izumi yawned as she got to get ready to close the store. She was about to lock up when a man with a dark complexion and wearing sunglasses came in. "How may I help you sir?" She smiled and she welcomes him. "I'm looking for Fullmetal, where is he?" Scar looked around while saying it.
Izumi suddenly got very mad when he said Edward military name. "What heck you want with Edward. He not here but if he was I don't mess with people who know his military name." as she banged her fists in the counter.
"It is none of you concern why I want to know where Fullmetal is." He walked towards the when Izumi grasp his left arm. "Let me go right now miss, I told you it none of your concern. It between me and him." Staring right at her.
She did not let go of his arm but suddenly got very red in the face. "I do have the right to know. I'm his Sensei, I took cared of him and his brother while they where in my care for a whole year. So don't you dare tell me it none of my concern!"
He look away from Izumi and sighed. "It nothing personal. It something I have to do. I'm sorry for the trouble miss. "
She finally let go of his arm and looked away. "Just please don't hurt them. They're just like my children to me."
Scars open the door and just before he left, he turn around to face Izumi one more time. "I can't promise you anything." And with that he left.
Izumi locked the door and left to go home to see how Sig was doing.
