Luise Meyrink is the character in KOF: Maximum Impact 2; in most scenarios, she will be the last obstacle before the last boss.
Both of her designs follow a butterfly motif, specifically after the Morpho butterfly. Her in-game information is unique in that her profile and storyline were written to be deliberately different from one another. Her character role is to serve as the "older sister with years of experience" as well as the median between both Meira brothers.
Luise is a mysterious woman with a strange and regal appearance. In her profile, it states that Luise is the daughter of Professor Detlev Meyrink, a well-known and respected authority on rocket science. She enters KOF in search of him when he was kidnapped by the syndicate, Addes. She seems to be a naturally talented fighter, and ambiguously warns challengers about Jivatma's plans. She also knows information regarding Alba's and Soiree's past and the being "Judeim", but chooses to not divulge this to them in detail.
During her storyline, it is revealed that she is one of the last members of the ageless alien race known as the Zoan. Jivatma refers to her various times in the game as "Lakia" (ラキア, Rakia), most likely her original name. Her real motive for the tournament is to pursue and destroy beings such as Jivatma, an entity who has caused mischief and murdered several Zoan in an undisclosed past incident. He tempts her to join him in exchange for a spaceship trip back to her home, but she refuses and prefers to wait until human kind can travel to space naturally. During the game's credits, she and Alba are seen starting a travel together, most likely searching for Soiree and Jivatma.
With an extreme love for her people, Luise is very proud of her Zoan identity. She wishes to destroy Jivatma, not for revenge, but for knowing that if he is kept alive, he will kill even more. She starts to relate with the Meira brothers and becomes a mediator between them.
