Lua Klein

is a woman whose dream is to be killed by Ladd Russo, her lover and fiancé.

Appearance Lua has waist-length brown hair that has long bangs parted to the left, lifeless brown eyes (murky green in the anime) and translucent skin that gives her the appearance of an ephemeral specter, although Graham Specter has called her so pretty that she resembles an elegant fairy tale princess. In accordance with Ladd Russo's white-themed dress code, Lua wears a formal sleeveless white dress for the Flying Pussyfoot journey, along with a white flower in her hair and long white gloves.

Personality Lua is a somber young woman who is defined by her desire to die—or rather, her desire for someone to kill her and enjoy the act, since she disdains suicide—her desire for death so visceral that she has forgotten the reason she wanted to die in the first place. In meeting Ladd Russo, her desire has narrowed even further: she wants nothing more than for Ladd to be the one to kill her, as she is certain he will have fun in the process. He is no mere means to an end; she loves Ladd deeply, and can no longer imagine a world without him in it. No matter how odd their relationship seems, it is a consenting one; the idea of Lua dying at Ladd's hands is one that they both find genuinely romantic. Lua's demeanor is one of elegant serenity as she steps as quietly whenever she talks and her placidness owed to her ability to 'accept everything'; no matter how grotesque or outrageous the situation, she confronts it head on. For all of Lua's pessimism, her steadfast ubiquitous acceptance leads her to "always find a way forward" no matter how bleak the situation. Her hybristophilia is evident every time she smiles and/or blushes at the thought of Ladd killing her, and she has a hobby she genuinely enjoys: assembling blank jigsaw puzzles. Once she assembles the puzzle, she will paint a picture over the pieces and then break the puzzle apart—after which she is said to give a 'hollow laugh'.
