Attack on titan : The last humanity's mage (Levi/Eren/Mikasa love story)

Prologue

"Akira, Luna, I have got a mission for us. Go and pack your things. We will go in 30 minutes. Hurry up, Luna, Akira." Said a blonde haired girl named Lucy Fullbuster. She was a little sister of Gray Fullbuster and also a cousin of Luna Heartfilia. Akira Dragneel was a niece of Natsu as his father was Zeref Dragneel who was an older brother of Natsu Dragneel. Luna and Akira nodded their heads as they quickly left the Fairy Tail guild. This is their second mission with Lucy.

Lucy was not married yet as she didn't find any love interest in her life. Her brother, Gray had married Juvia five years ago and had two kids. So she took care of Luna by herself as she didn't want to trouble Gray. She also took care of Akira since Natsu married Lisanna after Gray married Juvia and they have two kids. Akira didn't mind that Lucy take care of him as he like her. Akira had meet Zeref once since Natsu and Lucy were going to stop Gray from fighting Zeref by himself. Akira know that Zeref never know him so Akira just bid him a farewell before leave with Lucy and Gray as they let Natsu fight Zeref alone.

It was hard for Akira but he already get through by himself after his mother's death. Natsu had accept him as his niece even Natsu have a childish attitude that make Akira get headache of him. Fairy Tail members were already being couple except Lucy, Marco, Wakaba, Freed, Bickslow and Gildarts. Erza had married Jellal one year after Natsu and Gray following by Laxus who married Mirajane. Gajeel had married Levy early before Gray and Natsu. Gray had advice Lucy to find her partner make Lucy sigh at him.

The next day, Lucy, Akira and Luna were done their mission to catch thugs who trying to steal money from merchants. Lucy had send thugs to councils. When the council guards were take them, a leader of thug seem not accept his defeat at Lucy. He decides to use his dark magic on them as he throw at Lucy, Luna and Akira. Lucy had notice it was late to protect herself and her teams. That dark magic had open a portal which swallow Lucy, Akira and Luna before it disappeared. The council guards were froze to see them disappeared. They were only heard an evil laugh from a leader of thug before he get beaten by Lahar who seem furious.

Lucy, Luna and Akira were send out to another world that they didn't know anything. A large hole on the ground had getting attention to another people who flying around after kill the creatures. They were going to where Lucy, Akira and Luna come from. Lucy had woken up as she saw the sky make her get up. She was froze to see a few peoples who wearing soldiers uniform. Luna and Akira were also woken up like Lucy. Just like Lucy, they were speechless to see unknown people. Lucy have a bad feeling about the world that they come in. One of them who seem like a leader come over Lucy. He was a Commander of the survey corps named Erwin Smith. Lucy can feel his aura which she need to be careful with them.
