Character Setting

Edit

Risa Koizumi is the main character of Love Com, known for her tall stature and vibrant personality. Though she doesn't excel academically or athletically, her bickering, comedic dynamic with Atsushi Ōtani is highly entertaining, and she typically takes the role of the joker. Initially, Risa develops a crush on Ryoji Suzuki, but after he starts dating Chiharu Tanaka, she eventually realizes her true feelings for Ōtani. Risa stands out due to her cheerful, resilient spirit—even when faced with setbacks, she quickly bounces back. Despite often being called nicknames that poke fun at her height, she is often described as quite beautiful. Her journey through high school centers on embracing her feelings, pursuing friendship, and finding her own path for the future.

Risa Koizumi is notably tall for a Japanese high school girl.

  • Middle school, second year: 167 cm
  • First year of high school: 170 cm
  • From second year of high school: 172 cm
  • Weight: 50 kg

She is described as attractive, with a presence that catches attention when standing alongside other beautiful characters like Haruka Fukagawa. Risa prefers comfortable and affordable clothing, and her favorite colors are red and yellow.

Risa is outgoing, loud, and optimistic, always bringing energy to her surroundings.

She is easily cheered up by encouragement and is straightforward about her emotions (once she recognizes them).

Risa loves gaming and is a huge fan of the musician Umibōzu.

Her humor shines most in her "manzai" (comedic duo) routines with Atsushi Ōtani, where she usually plays the joker to his straight man role.

Although she struggles with academics and sports, her determination and lively spirit make her the heart of her group.

  • Birthday: August 3
  • Blood Type: O
  • Family: Lives with her parents and younger brother Takahito Koizumi; she also has a grandfather who does not live with them.

Her surname, Koizumi, was inspired by Junichiro Koizumi, the Prime Minister of Japan when the manga series began serialization.

While not academically gifted or sporty, Risa is exceptional at joke routines and has natural charisma.

She served as the class president for all three years of high school, partly because her homeroom teacher, Kiyoji Nakano, forced her into the role.

  • Atsushi Ōtani: Close friend, partner in comedic routines, and eventually her boyfriend. Their relationship becomes iconic among classmates and friends.
  • Ryoji Suzuki: Her initial crush, which turns into friendship after he begins dating Chiharu Tanaka.
  • Nobuko Ishihara: Her best friend, who supports Risa through various challenges and encourages her to pursue being a stylist.
  • Takahito Koizumi: Her younger brother.
  • Umibōzu: Her favorite musician and a significant influence in her teenage years.

She is supported by her family and friends as she navigates love, growth, and self-acceptance.

High School Years and Struggles

Risa starts high school towering over most of her classmates, which garners her many nicknames—"giant girl" and "giant goddess" among others. She is often teased about her height, particularly by Atsushi Ōtani, whom she at first sees as a comedic partner. Risa is tricked into becoming class president and, despite her protests, holds the position all three years.

Romantic Developments

She initially has a crush on Ryoji Suzuki. However, after he begins dating Chiharu Tanaka, Risa gives up on him. As Risa and Atsushi Ōtani tackle their own romantic struggles and misunderstandings, she gradually realizes her feelings for him.

Embracing Her Feelings

Inspired by Seishirou Kotobuki's advice, Risa becomes more honest about her emotions. After numerous comedic and heartfelt misadventures, she and Atsushi Ōtani become an official couple, recognized and celebrated by classmates and both their families.

Personal Growth and Graduation

Risa's positivity and ability to recover from disappointment earn her a reputation for resilience. She has ambitions of becoming a stylist, deciding to attend a technical school over a junior college, spurred on by Nobuko Ishihara’s encouragement. During her senior year, she briefly forms the "Mighty Club" (named after Kuniumi Maitake, who matches her "ideal prince" type) as a tongue-in-cheek reaction to Atsushi Ōtani's obliviousness to her feelings, but dissolves it after his negative reaction.

Hidden Connections

Unbeknownst to both at the time, Risa and Atsushi Ōtani crossed paths at an Umibōzu concert during the spring break after middle school graduation. They only realize this coincidence three years later, after finishing high school.

  • Her ideal type is someone taller than her and prince-like, exactly fitting Kuniumi Maitake’s description.
  • Favorite food: boiled eggs in oden.
  • Her comic duo act with Atsushi Ōtani is compared to famous Japanese comedy teams.
  • Her nickname "Koizumi" comes from Japan’s former Prime Minister Junichiro Koizumi.
  • Risa is a serious gamer, often surprising her friends with her skills.

  • “I’m not Ōizumi, I’m Koizumi.” (A self-deprecating play on her own height compared to her name.)

Risa stands as a symbol of self-acceptance—embracing both her strengths and insecurities. Her exuberant, comedic charm and honest heart make her a beloved protagonist in Love Com.
