Ruka Sarashina is a girl from Tokyo known for her short hair and signature ribbon. She is small at 153cm tall but has a curvy figure. Her birthday is August 26 and her blood type is O. Ruka is officially Shun Kuribayashi’s girlfriend, but secretly works for the "Maple" rental girlfriend agency, where she uses the name Ruka Sarashina. She has a heart condition, causing her heart to beat slower than most people’s. This led her to try new things to feel excitement, which is why she started working as a rental girlfriend. At first, she looked down on the whole idea, but meeting Kazuya Kinoshita changed her mind. Ruka now tries very hard to become Kazuya’s real girlfriend, causing lots of funny and dramatic moments.
Ruka Sarashina has short hair and always wears a large bunny-eared ribbon, which makes her easy to recognize.
She is 153cm tall and has a curvy, "little sister" kind of look, which many people find cute.
She usually has a cheerful and energetic vibe.
Ruka is full of energy and always outgoing, not afraid to say what she thinks or go after what she wants.
She can be a bit pushy, especially with Kazuya Kinoshita, and sometimes causes trouble when she wants things her way.
Even though she seems bold, Ruka knows her actions can be a hassle to others and sometimes feels bad about it.
She also has a very determined side, especially when it comes to love.
Born August 26, Ruka grew up in Tokyo.
Ever since she was young, Ruka has had a condition called bradycardia, making her heart beat slower than other people.
Heavy exercise or getting excited would make her dizzy, so she missed out on the usual thrill many people feel.
She hoped that falling in love would finally make her heart race.
Because of this, Ruka joined the "Maple" agency as a rental girlfriend, searching for someone who could make her feel true excitement.
Ruka does not have any superpowers, but she is brave and persistent, willing to try new things for the chance to feel “excited.”
She also adapts quickly, as seen when she joins the Maple agency or goes after Kazuya.
Ruka is introduced as Shun Kuribayashi’s girlfriend, but this is just part of her rental girlfriend job.
She becomes interested in Kazuya Kinoshita after seeing how kind he is to Chizuru Mizuhara, another rental girlfriend.
Ruka considers Chizuru her main rival in love and tries hard to win Kazuya’s heart.
She boldly announces to Kazuya’s grandmother Nagomi Kinoshita that she is his girlfriend, leading to funny misunderstandings.
Ruka also has a complicated rivalry with Mami Nanami, who uses any trick to get what she wants—much like Ruka.
Beginning as a Rental Girlfriend
Ruka Sarashina joins "Maple" to look for something that makes her heart beat faster.
At first, she looks down on people who use rental girlfriend services, thinking they are shallow and unserious.
Meeting Kazuya Kinoshita
Ruka’s opinion changes after she meets Kazuya and sees how seriously he cares for Chizuru Mizuhara.
She realizes she finally feels true excitement and decides Kazuya could be the one she’s searching for.
Becoming Kazuya's "Trial" Girlfriend
Ruka starts visiting Kazuya’s house and pushes to become his "trial" girlfriend—only with certain conditions.
She tries hard to show her love, even if it means being pushy or bold.
Love Rivalry and First Kiss
Ruka tries to get close to Kazuya’s grandmother and boldly tells everyone she is his girlfriend, despite Kazuya already introducing Chizuru as his girlfriend.
People start to think Ruka is just a liar.
She thinks of Chizuru as her main rival and wants to beat her at romance.
Ruka also kisses Kazuya before Chizuru does, and tells him it was her first kiss.
Refusing to Let Go
When Kazuya can no longer hide his feelings for Chizuru, he tries to break up with Ruka.
Ruka refuses to accept the breakup and continues to be close to Kazuya, no matter what.
Doing Whatever It Takes
Ruka is not afraid to use any strategy to reach her goals, even if it causes problems for others.
This makes her similar to Mami Nanami in some ways.
She sometimes stirs up trouble, but always with her heart set on love.
On April 1, 2020, the official anime Twitter account joked that Ruka Sarashina had become the main heroine of the Rent-a-Girlfriend anime.
This was just an April Fool’s Day joke.
