My hero academy — The quintuplets

(Itsuki is the fifth of the quintuplets; she has long red hair and is the most studious but also the most formal of the quintuplets. She loves to eat a lot. She wears two star-shaped hair clips, a red blouse, a black jacket, a green midi skirt, long socks, and black ballet flats.) She has dark blue eyes.) Itsuki is a serious and dedicated girl [10] who usually wakes up early compared to her sisters. [11][12] She is well-mannered; she is never late or absent from a class, [13] and always speaks formally. In Japanese writing, she speaks almost exclusively with a keigo speech pattern. Nino, her older sister, comments that Itsuki is very proper. [14]

Itsuki is a girl who holds grudges,[15] as shown when she rejects Futaro's private lessons partly because of a previous fight they had. She is also someone who can't be honest with herself and has difficulty being more direct.[16][17] Both qualities often cause her to fight alone. She gets irritated easily, whether by unfavorable situations,[18] scary things[19] or her stubbornness.[20][21][22]

She has a huge appetite and is frequently seen eating something or being hungry throughout the series. It seems she doesn't mind treating her sisters unfairly when it comes to food-related matters. [23] This is shown in a scenario where she proposed to her sisters that they share their cakes; it is suspected that Ichika tried all the flavors. [24]

According to Futaro, each Nakano has its own characteristics in relation to its leaves. [25] In Itsuki's case, she would prefer to use an eraser instead of scribbling on them. (She has Phoenix powers, being able to use flames, and also transform into a large Fire Phoenix.)

(Yotsuba is the fourth of the quintuplets; she has short orange hair and is sporty and cheerful. She wears a green bow shaped like two rabbit ears, a yellow blouse, a green midi skirt, and black ballet flats. She was the first of the quintuplets to meet Fuutarou Uesugi and is in love with him, just like her sisters. She has dark blue eyes.) Yotsuba is an active, cheerful, and calm girl. She speaks loudly, spontaneously, and sometimes distractedly. She is the type of person who can't say no to someone who needs help [8] and is frequently seen helping others, either directly or indirectly.

Although outwardly cheerful and friendly, she harbors feelings of inferiority toward her sisters and her own abilities. Because of this, she developed a desire to be different from them. She cut her hair shorter, put on a ribbon, and excelled in extracurricular activities.

Although initially portrayed as a terrible liar, she is later shown to possess some skill in lying herself. (She has wind control powers, being able to manipulate the wind and air to her advantage.)

(Miku is the third of the quintuplets, has medium-length reddish-brown hair, loves Japanese history. She wears blue headphones around her neck, a light blue sweatshirt, a white blouse, a green midi skirt, black tights, and black ballet flats. She has dark blue eyes.) Miku is a quiet and reserved girl with a pessimistic way of thinking and low self-confidence, even to the point of belittling herself. [9] Futaro Uesugi observes that she lacks faith in herself. [10] Contrary to her reserved personality, she can speak directly and doesn't hesitate to confront others. [11] She can also be a bit possessive, as when Yotsuba kisses Futaro on the cheek to wipe off some cream, and generally sulks whenever another girl, especially one of her sisters, gets too close to Futaro.

It is shown that she has an obsession with generals from the Sengoku Period. She is heavily influenced by their philosophies, to the point that it affects her behavior in real life. She hides this fact from everyone and is embarrassed when Futaro finds out. When Futaro challenged her to a historical knowledge duel, she donned armor similar to that of Takeda Shingen.
Despite her somewhat negative outlook on life, such as when she asks Futaro to give up on her, she is the first sister to follow the Gotoubun Principle. Miku always remembers to follow this principle, even going so far as to compromise her own interests to ensure everyone is treated equally. Miku is also a genuinely kind person: she becomes the second of the Nakano quintuplets, after Yotsuba, to accept Futaro, and the first to openly fall in love with him. Her interactions with him after her first character arc show her being completely supportive, kind, and concerned for him. She is also seen helping an elderly woman cross the street. (She has ice powers, capable of freezing an entire city if she wants, and can even create ice weapons.)

(Nino is the second of the quintuplets, she has short reddish-pink hair and is a Tsundere. She wears two butterfly bows, a white blouse, a black jacket, a green midi skirt, thigh-high socks, and black ballet flats. She has dark blue eyes.) Nino has an extroverted personality and is socially conscious, resulting in her having many friends and being a very sociable person. [13] She has a sharp tongue [14] and speaks bluntly when confronting others, even her sisters. [15] Her rebellious attitude makes her the least cooperative among the sisters, causing her archetype to resemble that of a "tsundere".

Despite her cold and gruff exterior, Nino is caring [16] and protective,[17] as when she is moved by Futaro Uesugi's past; commenting that it is heartbreaking. This is also evident from her willingness to act as the family cook, ignoring concerns about her own appearance (culinary activities can cause bad smells, damaged nails, etc.). She is also always shown carrying bandages, possibly as a precaution against Yotsuba Nakano's boisterous behavior.

Her interests seem to lean more towards romance than anything else. An example of this is when she wanted to watch a romantic movie, while Itsuki Nakano preferred a science documentary. With this in mind, she likes to openly express her feelings for Futaro, whether in front of him or her sisters.

According to Futaro, each Nakano quintuplet has its own characteristics regarding its papers, but in Nino's case, she will file her papers meticulously. (She has psychic powers, being able to levitate things, and the angrier she gets, the more intense the psychic energy becomes.)

(Ichika Nakano has short, chic pink hair and is the oldest of the quintuplets, and the laziest, but also the most astute and mature, and is starting her career as a film actress. She wears a white shirt, a yellow jacket tied at the waist, a green midi skirt, black flats. She has dark blue eyes.) Ichika acts like the older sister to her sisters, as she appears to have a calm and serene demeanor; making her an approachable person. [12] Futaro Uesugi noticed that her smile is fake and encouraged her to let go of that kind of smile. [13]

Initially, she had a pessimistic attitude towards her sisters' learning abilities, becoming one of the obstacles to Futaro's private lessons at the beginning of the story. [14] After being inspired by him, she began to change her mind and started taking her studies seriously. [15] He also helped her resolve any problems she had with her sisters, making them closer than ever. [16] Despite her smug expression and teasing behavior, Ichika demonstrates a weakness for romantic moments, blushing whenever she thinks about it. [17]

According to Futaro, each of the Quintessential Quintuplets has its own characteristics in relation to its leaves. [18] In Ichika's case, her writing and paper would be sloppy. It was also observed that she learns things quickly and gets annoyed when her sisters make decisions without her presence.

As the eldest sister is proud of herself, she plans to succeed first before telling her sisters about the job. She is shown studying between filming; whether in a car on the road or late at night. Futaro was also impressed by how she managed to balance work and studies. (She has hypnotic powers, being able to hypnotize anyone.)

Futaro Uesugi, a serious, focused, and very intelligent boy, lives with his little sister Raiha Uesugi, a very helpful and sweet 6-year-old girl, and his father, Isanari Uesugi. He has straight black hair with a left-swept fringe, yellow eyes, and usually wears a gray sweater, a white shirt underneath, dark green jeans, and black shoes. According to Isanari Uesugi, Futaro resembled his father as a child, with his eccentric personality, difficulties in school, frugal lifestyle, and preference for solitude. Someone comments that Futaro is always like that, trying not to associate with anyone. Ichika Nakano observes that Futaro is direct and doesn't mince words. Yotsuba Nakano's first impression of Futaro is of a gloomy boy without many friends. His facial expression is always serious, sometimes with a grumpy and irritated look, and he rarely blushes or gets embarrassed. As he grows older, he becomes more obsessed with his studies and more pompous and antisocial. Despite his initial facade, he is actually a very caring person, especially towards his sister Raiha Uesugi.

Futaro is known for having a large ego and a lot of confidence. He is direct, tactless, brutally honest, and rude; but in reality, he is capable of controlling his emotions. Despite this, Futaro can momentarily lose his composure when agitated and confronted with unfavorable circumstances. Initially, he also disliked getting involved in other people's problems, finding them troublesome. Despite his lack of tact, he is experienced enough to know what to say in specific situations when confronted; he rarely gives up when trying to achieve a specific goal.

Despite his egocentric nature, Futaro is very hardworking and has a lot of patience. (He possesses superhuman intelligence, capable of building everything from weapons to robots.)
