五等分的新娘

Ichika Nakano Nakano Ichika

The eldest of the quintuplets, a mature and alluring rookie actress and model with a slightly devilish air. She appears composed, but is actually emotionally delicate, always hiding her true feelings behind a smile. She is closest to Miku, yet was the first to notice that Miku liked Fuutarou; after the fireworks festival she built a partnership with Fuutarou, finding herself torn between family affection and love.

Nino Nakano Nakano Nino

The second of the quintuplets, stylish and outgoing with a sharp tongue, but actually afraid of loneliness and pure-hearted, valuing family above all. She is good at housework and cooking, and is the family's head chef. She was initially the most resistant to Fuutarou, but later was the first to confess; Ichika described her as a "runaway train of love"; after the final exams she cut her long hair, symbolizing that she had let go of her attachment to the past.

Miku Nakano Nakano Miku

The third of the quintuplets, introverted and quiet with little self-confidence, yet she has the best grades among the five sisters and was the first to fall in love with Fuutarou. She loves Sengoku history and is skilled at disguising herself as her sisters. Because Fuutarou discovered and affirmed her interests, she regained her confidence, and she was the first sister to accept Fuutarou as a tutor; during the forest school trip she told Ichika she wanted to compete fairly.

Yotsuba Nakano Nakano Yotsuba

The fourth of the quintuplets, she is innocent and simple, full of energy, always greeting people with a smile, and has outstanding athletic ability but the worst grades. She always thinks of others, yet doesn't know what she herself wants.

Itsuki Nakano Nakano Itsuki

The fifth of the quintuplets, she is earnest and straightforward, speaks politely but isn't honest about her feelings, and loves to eat and cry easily. She was the first sister to meet Fuutarou, and also the first to reject him. Because of her mother's words she was wary of Fuutarou, but during the hot spring trip she redefined their relationship as friends, and set her goal on becoming a teacher; she is the only sister who knows where Fuutarou lives, and the one who visits the Uesugi household most often.

Fuutarou Uesugi Uesugi Fuutarou

The male protagonist of this work, a gifted student who has ranked first in his grade for years, and who takes on tutoring the Nakano quintuplets because of his family's poverty and debt. On the surface he is serious and humorless, but inside he is honest and can see through others' emotions; in sixth grade he met a girl in Kyoto who changed his life.
