Simon no Mikoto

Simon no Mikoto (シモンの美琴, Shimon no Mikoto) was the older brother of Kagura no Mikoto.

Appearence
Simon was a very massive, tall and muscular young man, with his overly large arms and hands appearing even larger compared to his extremely thin legs.

As a child, Simon's attire was that of a slave in the Tower of Paradise, which consists of a sleeveless shirt and a pair of light pants reaching down below his knees, held up by a simple, rudimentary rope belt tied in a knot on the front.

Yggdrasil Island Arc
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.

After eight years pass, he, along with Shô, Wally, and Millianna, appear at a casino where Team Natsu is having their vacation. He begins by attacking Gray Fullbuster and Juvia Lockser, demanding to know where Erza is. When the two refuse to reveal her whereabouts, Simon uses Dark Moment, making the room pitch black, and seemingly defeats the two. Paul Gekko and his teammates invade the tower, and Erza reveals to the group about her past, and how Cloud framed her for betraying her friends and left them, but in reality she was banished, as Jellal wanted to finish the tower to bring Shinju back. Shô appears shocked by the truth that Jellal lied about Erza, betraying them. As he falls into a state of confusion, Simon appears telling Shô what Erza just said is true, and he knew all along that Jellal has lied about Erza's betrayal. Everyone then agrees to work together to stop the Evil King's Incarnation's plans. As the team runs through the tower to stop Jellal, Simon tries to contact Wally and Millianna, but he is blocked. Gray questions Simon's trust as they travel. Simon tells him he knew skilled Mages like him and Juvia wouldn't die so easily, and he had faith Natsu wouldn't be defeated by Wally so easily. Simon then praises Paul Gekko, telling his friends that they have yet to realize Natsu's full potential as a Dragon Slayer. When Etherion hits the Tower of Heaven, Simon is shocked that he is still alive. In the Middle the fight against Cloud and the Ten-Tails, Simon throws his body in front of the Juubi's Tailed Beast Bomb protecting Erza. He falls to the ground and with Erza by his side. Simon then confesses his love to her and sadly dies.
