Edit

Mami Nanami is a main character from Rent-a-Girlfriend. She is Kazuya Kinoshita's ex-girlfriend, and plays an important part in the story's drama. Mami is friendly at first glance but hides a much darker, jealous side. After breaking up with Kazuya, she becomes involved with his life again when she notices him with Chizuru Mizuhara. Motivated by complex feelings and jealousy, Mami starts to interfere with Kazuya and Chizuru's relationship by using sneaky tactics and manipulation. Her actions and background make her one of the most realistic and controversial characters in the series.

Mami Nanami is a cute and charming girl.

She stands 158 cm tall.

She has a very appealing look, which is often said to be the cutest in the story.

Mami usually comes across as friendly and easy to talk to.

She has a soft and angelic atmosphere.

However, deep inside, she can be very cunning and mean.

She often shows a dark and cruel side that surprises people close to her.

Many see her as a sweet person, but she secretly has a sharp tongue and negative feelings.

She complains about others on her secret social media accounts, using words like “virgin” for Kazuya, “that girl” for Chizuru, and “clingy” for Ruka Sarashina.

Mami grew up in a wealthy home in Tokyo.

Most of her life was controlled by her strict father.

Her father decided what she owned, where she studied, who she befriended, and even who she would marry.

In high school, she tried to break free by dating a boy for the first time.

Her father ordered her to break up, and when she refused, her boyfriend chose safety over her and left.

This experience made Mami lose faith in love and feel bitter about relationships.

Since then, she hides her true feelings behind a fake smile and sometimes acts to make couples break up.

She was Kazuya Kinoshita’s girlfriend for one month before she broke up with him.

She attended Nerima University and studied German.

She is part of the same tennis club as Takeshi Sasano.

She has a younger brother.

Mami tries to get back in touch with Kazuya once she sees him with Chizuru Mizuhara.

After learning about Chizuru’s secret job, she becomes even more involved in their lives, even contacting Kazuya’s grandmother on social media.

Mami is clever and sneaky.

She can easily dig up information on others and plan actions in secret.

She can pretend to be friendly while hiding her true motives.

She was born on November 13.

She is from Tokyo.

She is a student at Nerima University.

Breakup with Kazuya

Mami Nanami started out as Kazuya Kinoshita’s girlfriend.

They dated for just one month before she broke up with him.

For Mami, Kazuya was not a special person, and she felt it didn't matter much who she dated.

First Encounters and Jealousy

After the breakup, Mami saw Kazuya with a new girlfriend, Chizuru Mizuhara.

She felt like Kazuya had gotten a new girlfriend just to spite her, and this made her unhappy.

When she first met Chizuru, Mami did not like her.

She wanted to break them up.

Hidden Feelings and Actions

Even though she acted like she had moved on, Mami began to feel jealous and possessive when she saw Kazuya with other girls.

She started to watch Kazuya closely and interfered with his life.

She used her secret social media accounts to complain about Kazuya and the girls around him.

Discovering the Truth

One day, Mami saw Kazuya on a practice date with Sumi Sakurasawa.

She decided to find out more about Sumi and ended up learning Chizuru Mizuhara's secret—she was actually a rental girlfriend.

Mami then pretended to be a customer and went on a rental girlfriend date with Chizuru.

She also made contact with Kazuya’s grandmother’s social media account and tried other ways to get involved secretly.

Against Love and Hurting Others

Mami does not believe in love anymore.

Her past made her bitter, and she deals with her pain by causing problems for others who are in relationships.

After seeing Kazuya falling for Chizuru, she pushes even harder to ruin their connection, even if it means involving Kazuya’s whole family.

She is known for her realistic and messy feelings, which make her stand out among other characters.
