The Quintessential Quintuplets Characters

A second-year at the top of his year who lives with his father and little sister in a small apartment. His mother has died, his father is in debt, and he has no friends and no interest in anything but study. He takes a well-paid job tutoring the Nakano quintuplets, hired to see all five through to graduation. In his student handbook he keeps a photo of a girl he met on a school trip to Kyoto as a sixth-grader, who inspired him to study. Blunt and tactless at first, he slowly comes to care about all five, and the whole series is framed as his memories on the day he marries one of them.

The eldest of the quintuplets, with short hair and a single earring. She plays the responsible big sister and loves to tease, but at home she sleeps a lot and her room is a mess. She is secretly working as an actress, which comes out at the fireworks festival, and she later takes on more roles to keep money coming in when the sisters move out on their own. Her feelings for Futaro lead her to pose as Miku on the third-year trip to Kyoto, which she comes to regret and apologises for.

The second sister, who wears her long hair with two butterfly ribbons until she cuts it short in season 2. She cares about her sisters more than anything and at first sees Futaro as an intruder, doing all she can to keep him out of their apartment. A skilled cook who runs the family kitchen, she falls for Kintaro, the blond boy Futaro poses as at the school camp. She becomes the first of the sisters to tell Futaro plainly that she loves him, and wins a job at the bakery where he works.

The third sister: quiet, calm and seldom seen without the headphones around her neck. She secretly loves the warlords of Japan's Sengoku period, does best of the five in Futaro's first test, and is so good at disguises that her sisters ask her to stand in for them. She is the first to warm to Futaro after Yotsuba, but doubts she can compete with her sisters. She practises cooking, which she is bad at, for his sake, and discovers that she loves baking for its own sake.

The fourth sister, known for the ribbon she ties like a pair of rabbit ears. Cheerful, friendly and the most athletic of the five, she can never refuse a request, so the sports clubs keep borrowing her even before exams. She is the only sister who accepts Futaro as their tutor from the start, and he leans on her to reach the others, though she is the weakest student of the five; the sisters left their old school together after she failed its exams. In the third year she volunteers herself and Futaro as class representatives.

The youngest sister, with long hair, a stray tuft on top and star-shaped hairpins. She is the first of the five Futaro meets, at lunch in the school cafeteria, and after he is rude to her she stays prickly with him for a long time. Serious, polite and the hardest worker of the five, she is also the biggest eater. She was always close to their late mother, a teacher, decides to become a teacher herself and starts interning at a cram school in her third year.

Futaro's cheerful little sister, still at primary school, who does the cooking and is effectively the head of the household. Her cute expressions are a running gag: they talk Futaro, Yotsuba and Itsuki into almost anything. When Itsuki ends up eating dinner with the Uesugis on the very first night, Raiha invites her back. Before the school camp she gives Futaro a lucky charm, and in the flash-forward to his wedding years later she finds that he still wears it.

Futaro and Raiha's father, a rather immature man with golden hair and sunglasses pushed up on his forehead, who tells his son not to study so hard. The family is poor and he is in debt, and it is he who lands Futaro the tutoring job with the Nakanos. He comes along when Futaro wins a trip to a hot-spring inn, where they run into the quintuplets.

The quintuplets' stepfather, a busy, reserved doctor who hires Futaro as their tutor. He lives apart from the girls and at first speaks to Futaro only by phone, warning him that he will be fired if even one of his daughters fails. Futaro later calls him out for neglecting them, and in season 2 a deal over the finals decides whether Futaro can come back as their tutor. He takes the sisters on a family trip to the hot-spring inn run by their grandfather.

The quintuplets' late mother, a strict, stern teacher whom her pupils nonetheless adored. She raised the five on her own, in poverty, until she married Maruo, and taught them that sisters share everything equally; the fireworks they watch together every year are a memory of her. Her former pupil Shimoda became a teacher because of her, and Itsuki hopes to follow the same path. The girl from Futaro's photo who reappears in season 2 goes by her name.

A handsome, popular classmate in the third year and the son of the school principal. He spent years ranked second in their year behind Futaro, who had never even noticed him, and sees Futaro as his rival. When the sisters' father wants Takeda to take over as their tutor, Futaro takes him on in the national mock exam while still tutoring the five, and beats him, earning his respect.

A classmate with brown hair and a fierce, delinquent look. Before the school camp he asks Ichika to the campfire dance, not knowing that Miku is standing in for her, and Futaro sends him off by pretending to be Ichika's boyfriend. Maeda's answer is to dare Ichika to dance with Futaro at the campfire. In the third year he is in Class 3-1 with Futaro and the five sisters.
