Lisanna is the younger sister of both Elfman and Mirajane, and she's also a member of Fairy Tail, like her siblings. Her magic is Take Over. Initially, her member stamp was on her upper left shoulder, but it's now on her left thigh.
It’s quite possible that Lisanna, Elfman, and Mirajane operated as a three-person team similar to Shadow Gear. Lisanna lost her life while trying to calm Elfman after his full-body Take Over went out of control. He quickly lost control and went on a rampage. Lisanna gave her life attempting to stop him. How exactly she managed this remains unknown. The mental and emotional trauma from Lisanna’s death severely crippled both Elfman and Mirajane’s powers. Mirajane lost her S-class rank and hasn’t fought since. Elfman suffered significant emotional damage and couldn't cast his Full-Body Take Over spell for some time. When he did try, memories of Lisanna caused him to lose focus.
When Lisanna was younger, she appeared very kind, much like Elfman, unlike Mirajane. She wanted to help Natsu Dragneel raise an unknown egg, knowing slightly more about it than Natsu. After seeing a softer side of the usually flamboyant Natsu, she remarked that he was a lot like her sister and jokingly suggested that perhaps later she should become his bride, which understandably freaked him out. It's shown that while the Earthland version of Lisanna is deceased, the Edolas version of Lisanna is still alive. Like her Earthland counterpart, she appears just as friendly and caring, seen when she scolds Lucy for bullying Natsu and tells Jet and Droy not to pick on Elfman. When Natsu and Happy see her, they both shed tears and tried to hug her in joy, which scared her. She doesn't seem to have the massive crush her Earthland counterpart had on Natsu.
In chapter 199 and Episode 95, it’s revealed that the Earth Realm Lisanna was sucked into Edolas and didn't actually die. After being taken back to Earthland by reverse anime, she was found by Panther Lily and brought to Natsu and the others. There, she explained everything to them and returned to the Fairy Tail Guild.
