Mirajane Strauss — Fairy Tail

Before the main story, Mirajane attempted to rid a village church of a demon and inadvertently absorbed its power. Her arm took on a demonic appearance, which frightened the villagers, and for a time she believed herself cursed or monstrous. After she joined Fairy Tail, Elfman and Lisanna chose to learn their own versions of Take Over to show that the power need not isolate her. Her siblings’ solidarity helped her accept herself and her place in the guild.

Mirajane’s earlier combative personality changed after a mission on which Elfman lost control of a full-body Beast Soul transformation and struck Lisanna. The siblings believed Lisanna had died. Devastated, Mirajane stepped away from active combat and became reluctant to use Satan Soul. During Laxus’s attempted takeover of Fairy Tail, Fried’s assault on Elfman draws out her suppressed power. Mirajane overwhelms Fried in her demonic form, but memories of Lisanna stop her from delivering a final blow. She instead reminds Fried that his guildmates are his friends, and their confrontation ends in remorse rather than further violence.

The Edolas storyline reveals that Lisanna was not killed: after Elfman struck her, an Anima pulled her into a parallel world. She eventually returns to Earth-land, reuniting with Mirajane and Elfman after two years apart. Later, on Tenrou Island, Mirajane and Lisanna confront Azuma of Grimoire Heart. He places Lisanna in a deadly timed trap to force Mirajane into battle. Unable to defeat him before the deadline, Mirajane shields her younger sister from the explosion and is badly injured.

After the Fairy Tail members on Tenrou Island return from seven years of disappearance, Mirajane represents the guild at the Grand Magic Games. Her match against Jenny Realight of Blue Pegasus turns into an unusual contest of appearances involving Transformation Magic before Jenny adopts a combat form. Mirajane answers with Satan Soul: Sitri and wins decisively. The match is a public reminder that the guild’s gracious hostess remains a formidable fighter.

In the Tartaros conflict, the enemy’s curse user Seilah exploits Elfman and the Strauss siblings become entangled in Tartaros’s plans. Mirajane and Lisanna are taken to the dark guild’s base, where Mirajane encounters the facility known as Hell’s Core. She uses her Take Over magic on its demonic appendages to destroy the regenerative laboratory that allows fallen Tartaros members to return. Facing Seilah’s overwhelming power, Mirajane manages to appropriate the effect of Seilah’s Macro curse and calls Elfman to their aid; he then strikes Seilah down. The conflict further reveals the siblings’ formative experience with Mirajane’s power.

During the war against the Alvarez Empire, Mirajane reveals Satan Soul: Mirajane Seilah, drawing upon the power acquired from her conflict with Seilah. She also uses the much more costly Satan Soul: Mirajane Alegria against Irene Belserion’s agents Juliet and Heine, defeating them before discovering they were actually enchanted swords. The effort leaves her weakened and exposed to Irene, who captures and attacks her. August inflicts an apparently fatal wound, but Brandish secretly reduces its severity, allowing Lisanna to find Mirajane alive.

After Tartaros, Fairy Tail temporarily disbands and later reunites; Mirajane returns to battle alongside her guild. During the war against the Alvarez Empire, she confronts Jacob Lessio. His reluctance to look directly at her gives her an opening, though she acknowledges that the victory would have been much harder if he had fought without that handicap. By the final chapter of the original manga, Mirajane remains part of Fairy Tail and her siblings’ lives. The manga does not assign her a separate, definitive romantic conclusion. Fairy Tail: 100 Years Quest is an official sequel and is not folded into this original-manga account.
