Simon lived a happy life with his younger sister Kagura Mikazuchi
in Rosemary Village, the same place where Erza also grew up. He was
kidnapped as a child and taken as a slave to build the R-System,
otherwise known as the Tower of Heaven. It was there that he made friends with Erza, Jellal.
Simon was a very massive, tall and muscular young man. He had proven to be logical and cautious, carefully examining situations
before taking further steps and choosing retreat or escape if pitted
against an insurmountable opponent, as well as being willing to wait for a long time before carrying out his plans for the sake of his friends and allies.
From his childhood he used to Love Erza and at the end he died protecting Erza. He was happy that at last he had done something for Erza.
