Mirajane Strauss

Mirajane is the cover girl or drawing point of the Fairy Tail Guild.

Personality
When Mirajane was an S-class mage, she was known as "The Demon" and had a very bad attitude with other members of the guild, usually dressed Gothic style and insulted everyone. However, due to a past incident involving the death of her younger sister, Lisana, Mirajane somehow lost much of her magical ability and her will to fight. Given the recent event of Elfman regaining his lost abilities and Mirajane's increased confidence, Mirajane recently regained her powers.

Mirajane plays a motherly role within the guild, and is often seen running the bar at the guild hall. She has rarely been shown to be in a bad mood, and can tolerate all of the guild's eccentricities. However, there have been a couple events that have disturbed Mirajane, including her discovery of the stealing of an S-Class job by Natsu Dragneel, Happy and Lucy Heartfilia, and her later disappointment with Laxus Dreyar following the destruction of the guild building.

Mirajane is also very determined to protect her comrades, going so far as changing her appearance in order to fool the Phantom Lord Guild into thinking she was Lucy, whom they were trying to capture. Along with running a bar, Mirajane shows great talent not only in modeling, but playing guitar and singing. She is much beloved not only among the Fairy Tail members but also many outside the guild.

History
When she was younger, she was actually very much like Natsu as he is now and she always fought Erza Scarlet similar to how Natsu fights Gray Fullbuster.

Macao arc
When Lucy enters Fairy Tail, a fight erupts. When Lucy askes Mirajane if she was suppose to stop it, Mirajane states that it happens all the time. When she is hit on the head by a bottle, she startes to bleed and states it's more fun like this which shocks Lucy.

Mirajane tells Lucy about Natsu's foster father, Igneel and history when Romeo Conbolt, Macao Conbolt's son, left the guild, followed by an angered Natsu.

Galuna Island arc
Mirajane helps explain to Lucy about the S-Class mages and the Guilds second floor. Later, she finds that Happy stole a S-Class mission during the night. She soon learns that Laxus did nothing to stop him and she gives him a piece of her mind.

Phantom Lord arc
Mirajane helps Team Natsu down to the basement as she explains that Phantom Lord attacked the guild during the night. She then defends Lucy as Makarov starts to spank her for taking a S-Class mission (despite only giving Natsu and Gray and smack on the head).

Later, after Makarov loses his power, Mirajane and Cana Alberona try to call Mystogan and Laxus back to the guild for the war effort. However, as Laxus badmouths the guild, Mirajane destroys the communication Lacrima and questions aloud to why someone so cruel is in Fairy Tail. As Phantom Lord descends, she declares she can't battle and instead transforms into Lucy, however she was captured and taken as hostage. Since she is a hostage, this helped Elfman regain his lost magic Full Body Takeover and gave him the ability to defeat Elemental 4 member Sol. After defeating Sol, Elfman makes his way towards Mirajane freeing her and apologizing to for taking the form that killed his sister again. However, Mirajane comforts him and figures out how to stop the Abyss Break. They later catch up to Gray who had just defeated Juvia and explain the details to him and then join up with Erza who just defeated Aria. Master Jose then arrives complementing them before taking Elfman and Gray out instantly and waking (and then retreating) when Master Makarov arrives. She is later seen celebrating the Guilds victory.

Fighting Festival arc
Mirajane plays a beautiful song for everyone, and as Natsu beings a huge fight, she changes to a rock song. The next day, she is apprehended by Gajeel Redfox so he can perform his own song. Later she preforms as returning champion in the "Miss Fairy Tail" pageant. She apparently shot down all hopes of winning as she turned her head into Happy and Gajeel's. She is then turned to stone with the other girls by Evergreen and saved later saved by Erza.

After Cana was defeated by Fried Justine, Elfman tries to fight Fried however he is also easily defeated. Fried then keeps attacking Elfman even after he's not able to fight, making Mirajane beg for him to stop. Fried keeps attacking and is about to kill Elfman with his magic, Yami No Ecriture, Annihilation. Mirajane let's out a burst of magic destroying some of the terrain around her stopping Fried from killing Elfman and regaining her old strength and abilities.

She completely overwhelms Fried in power and speed, even when he uses his Yami no Ecriture: Darkness turning him into a demon. Before knocking out Fried, she decides not to finish him off, and starts talking to Fried the guild members, this makes Fried cry. The battle ends as a draw since both Fried and Mirajane lose their will to fight.
