    Mami Nanami is the main antagonist of the 2017-present romantic comedy manga Rent-A-Girlfriend and its 2020 anime adaptation. She is a student of Nerima University and the ex-girlfriend of Kazuya Kinoshita, whom she dumped in favor of dating someone 'new', thus setting off the some events throughout the series.

    Why She Is Manipulative and Sociopathic

    1. To start with, Mami is hated for being a sociopath and manipulator, breaks up with Kazuya after a month, then tries to actively ruin his relationship with Chizuru out of spite.
    2. She emotionally and psychologically abuses Kazuya such as when Kazuya first introduced her to his "girlfriend" Chizuru.
    3. She has manipulated Kazuya's feelings for her, like kissing him and inviting to meet her at a pool alone in spite of being aware he had a girlfriend.
    4. Despite the fact that she was the one who dumped Kazuya, she is obsessed with sabotaging his relationship with Chizuru. The likeliest reason for this is because she was offended that he seemingly got over her in a short amount of time.
    5. In public, Mami appears to be a sweet and friendly person. Behind that persona, however, Mami has displayed sociopathic tendencies, such as conniving, manipulative, and petty behaviors, especially revolving around Kazuya and Chizuru. When her friendly façade drops, her jealous and possessive feelings scare people around her.
    6. She attempts to insert herself into Kazuya's life by befriending Kazuya's grandmother.
    7. Her eyes and face she makes whenever she's in a bad mood, looks pretty creepy and unsettling to the viewers. She also shows this when Chizuru suggests that Kazuya could be the person who could make her truly happy.
    8. She acts like she's not very bright and admits she's rather stupid, which hides just how observant and cunning she can be. She figures out Kazuya's plan that if he confesses to Chizuru at the resort and become a real couple, it would allow them to get away with all of the lies they've told everyone as if they never happened.
    9. There is not a single sympathetic quality to her character, for neither the audience nor the cast. Every time a situation arises that makes it seem like she has or is developing redeeming qualities, she does yet another thing that shows she's a unsympathetic jerk or a sociopath.
    10. Chapter 215 does reveals Mami's backstory and why she's determined to destroy Kazuya's relationship with Chizuru. Her parents were incredibly controlling over her entire life to the extent of sabotaging her relationship with a boy in high school she was genuinely in love with just because they had arranged for her to be married off to someone else. While it does gain her a little sympathy, it does not excuse her behavior and actions.
    11. After learning the truth of Chizuru's rental girlfriend job, she exposes her relationship with Kazuya as a total sham in front of their friends and family.
    12. She has a habit of disappearing from the story for long periods of time only to reappear again just to cause trouble, serving as nothing more than being a plot device.
    13. She rarely gets called out on her behavior, making her a karma houdini.

    Redeeming Qualities

    1. Despite making creepy and unsetting faces, she genuinely has a cute character design.
    2. She actually used to be a sweet girl, but became the way she is now, because her parents ruined it for her by forcing her to breakup with the boy she loved for the sake of an arranged marriage.
    3. There are some fans who actually like her as a character, considering that even when she's tearing the others down, she's usually not wrong in her assessments of their flaws and failings.
    4. Ruka giving Mami a verbal smackdown in episode 19, about how she's the one who hasn't moved on and is pining after a man she can't have is very satisfying, given how it was one of the few times when Mami was actually called out on her behavior.
    5. Aoi Yūki and Laura Stahl both do a great job voicing her respectively.


    • The name Mami means "hemp, flax" (麻, ma?) and "beautiful" (美, mi?).
    • Mami's surname Nanami means "seven" (七, nana?) and "sea, ocean" (海, mi?).
    • Mami's favorite color is gold.
    • Mami's Twitter handle is @pyon_pyon210.
    • Mami is the only character in the series who can be considered as genuinely malicious.
