We're all still in shock over Bakugo's kidnapping... so we have to think about this calmly. It doesn't matter how righteous our feelings are. If we start another fight... if we break the law... then we're no better than the villains!
Tsuyu Asui to her classmates about Katsuki Bakugo's kidnapping in "From Iida to Midoriya"

Tsuyu Asui ( () (すい) 梅雨 (つゆ) Asui Tsuyu?), also known as the Rainy Season Hero: Froppy (梅雨入りヒーローフロッピー Tsuyuiri Hīrō Furoppī?), is a student in Class 1-A at U.A. High School, training to become a Pro Hero.


Tsuyu is a short girl of a relatively slender build compared to her classmates, who has notably large hands. Her appearance is rather frog-like; she has a very wide mouth, which dips down a little in the middle just like that of a common frog, and oval-shaped eyes with large, black irises, their lower eyelashes visibly pronounced, and she also demonstrates some frog-like mannerisms, like hopping on all fours instead of running and holding herself in a way that is somewhat connotative of a frog.

Her hair is a dark sea-green color, and is very long, reaching all the way to her waist, the ends tied together at the bottom in a bow of hair. She has two shoulder-length clumps framing her face, and shorter bangs between her eyes, some of them partially swept to each side.

Her hero costume consists of a bright green turtleneck bodysuit, tan-colored gloves with large buckles on each wrist guard, and two matching belts, one above her breasts, a strap at either side going around her shoulders, and one around her waist, little green dots embedded into it all the way around. Two black lines run all the way down her suit, each framed with yellow, and she wears tight black boots with markings in the shape of a “V” on her thighs, green webbed flippers resembling frogs’ toes on her feet. She wears a headband with a color matching that of her gloves, and goggles with dark green-tinted lenses attached on either side.

Her winter costume isn’t largely different, though she now wears a ring around her neck with two bubble-shaped objects just above her shoulders, presumably to help with the regulation of her body temperature (her Quirk causes her to hibernate when it drops a significant amount), and her goggles are newly fitted with a visor so she can wear them more comfortably. The markings on her suit are also slightly different, in that the two lines only start just below her breasts rather than from the top of her suit, and she has two rounder markings on her chest.



Tsuyu is a straightforward and laid-back individual who always speaks directly from her mind and what she thinks about others. Tsuyu prefers to be called "Tsu", but only by people she views as friends.[1] She commonly refers to everyone with the honorific "-chan", save for teachers and other authority figures.

Tsuyu's parents were always busy at work, requiring her to become the caretaker of her two younger siblings at a young age. Under these circumstances, Tsuyu grew into a highly mature and responsible individual who could divide her attention between school and home duties without letting one interfere with the other. This also means that Tsuyu knows how to lead and look after people, keeping them safe and at ease if they don't feel so. She has strong morals and principles and is willing to oppose her friends to defend them from decisions she considers rash. When several members of Class 1-A agreed to rescue Katsuki Bakugo after the Vanguard Action Squad Invasion, Tsuyu was the most outspoken against it, asserting that acting on their emotions and breaking the law to rescue him made them essentially the same as villains.[2]

Tsuyu worries about All Might

Tsuyu is noticeably calm and collected, being able to stay levelheaded and focused even during the most stressful situations. An honor student since middle school, Tsuyu has great judgment, can communicate her intentions easily, and is rarely moved by emotion, making her an incredibly dependable ally who's capable of covering for a partner's weaknesses. For those reasons, Recovery Girl describes her as a "perfect pillar of emotional support".[3] However, even Tsuyu has limits when it comes to staying composed, having broken down in despair or heartbreak a few times. Her words may also come off as unintentionally harsh thanks to her blunt honesty, resulting in her feeling guilty and regretful when she speaks out against her friends.

Tsuyu Going Hmm

Tsuyu's finger tic.

Her usual expression consists of a vacant stare, which makes reading her thoughts and emotions difficult for those around her while also creeping them out in the process. Tsuyu has a habit of tipping her finger against her mouth while speaking, pondering, or showing curiosity. She tends to say "ribbit", emulating a frog's croaking, at the end of her sentences, or as a replacement for many of her single word replies.


Overall Abilities: Tsuyu has proven to be a highly capable individual. Using the frog-based abilities granted by her Quirk, Tsuyu excels in both close-range and long-range combat. She employs a fighting style that involves a great amount of agility and powerful leaps to evade, surprise, and confuse her opponents, as well as using her increased leg strength to deliver powerful kicks. Tsuyu can also use her elongated tongue in a grappling or whip-like fashion. Tsuyu also possesses great camaraderie, effectively combining her own Quirk abilities with that of anyone with whom she is paired. Tsuyu is a very outstanding student with little to no weaknesses and can provide support to anyone, even someone as powerful as Fumikage Tokoyami, one of the strongest students in Class 1-A. Her overall abilities make her one of the strongest female students in her class.

Tsuyu's abilities garnered the attention of Nejire Hado, the third strongest student of U.A. High School's Big 3, who recommended both Tsuyu and Ochaco to intern alongside her under the tutelage of Ryukyu, the No. 10 (formerly No. 9) Pro Hero. At the beginning the Shie Hassaikai Raid, the Ryukyu Squad acted as the first line of defense against Rikiya Katsukame of the Eight Bullets and were able to successfully subdue him. During the first round of the Joint Training Battle, Tsuyu demonstrated the mettle to take on Jurota Shishida, one of the strongest students in Class 1-B, but she couldn’t keep up with the latter's enhanced prowess. Afterwards, Tsuyu used her incredible leg strength to break through the scale armor of Hiryu Rin, send him flying into Jurota (who was being subdued by Hitoshi Shinso), and secure victory for her team.

  • Enhanced Stamina: Through intense training, Tsuyu obtained an impressive amount of stamina. After having her stamina siphoned by a Trigger-enhanced Rikiya, Tsuyu was still able to hold her own against the Yakuza member for 20 minutes until the Trigger drug wore off, allowing the Ryukyu Squad to defeat him once and for all.

Keen Intellect: Tsuyu has proven to be very intelligent, scoring 6th place in the mid-terms, showcasing her proficiency in academics.[4] She is also very analytical, as seen in the U.S.J. Incident, wherein she not only deduced the Quirk similarities between Izuku Midoriya and All Might, but also surmised the League of Villains may have an effective way to carry out their plan to kill All Might. Her speculation was later confirmed, in the form of a Nomu. With her level-headedness and analytical skills, Tsuyu successfully helped Izuku and Minoru escape from the water villains that surrounded the trinity in the Flood Zone. For the First Term Final Exam, Tsuyu and Fumikage were about to fail against Ectoplasm, but Tsuyu, avoiding his attention, had Fumikage use Dark Shadow to close the gap between him and the replicating hero, in order to discreetly handcuff the latter, enabling the students to pass. During the Joint Training, she took advantage of Jurota's enhanced sense of smell by coating her remaining teammates, Denki and Hitoshi, in mucus so that their scents still be the same as her's, making the trio indiscernible to Jurota.


Frog ( (かえる) Kaeru?): Tsuyu's Quirk allows her to do anything a frog can do, such as:

  • Hopping at long distances.
  • Extending her tongue up to a maximum of 20 meters (which is strong enough to lift an entire person's body weight).
  • Sticking to walls.
  • Ejecting/washing her stomach.
  • Secreting a mild, itch-inducing toxin.
  • Camouflaging herself.

Since she is frog-like, when she is exposed to cold temperatures for too long, she goes into hibernation and is unable to function.

As part of her training, Tsuyu worked out all the muscles in her body, including her tongue, by rock climbing on the side of a cliff while having her elongated tongue remain in place at the top of the structure.

Super Moves

  • Camouflage ( () () (しょく) Hogoshoku?): Tsuyu uses her frog-like body to match the temperature and color of her surroundings in order to mask her presence.
  • Meteor Fafrotskies (メテオファフロッキーズ Meteo Fafurokkīzu?): Tsuyu and Ochaco work together to float debris and throw it at the enemies.
