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) () () Asui Tsuyu?), also known as the Rainy Season Hero: Froppy (梅雨入りヒーローフロッピ Tsuyuiri Hīrō Furoppi?), 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, its 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.

Due to her routine as caretaker of two younger siblings, Tsuyu is extremely responsible. She has strong morals and principles, and is willing to stand against her friends to defend them. When several members of Class 1-A decided to try to rescue Katsuki Bakugo, Tsuyu was the most outspoken against it, asserting that acting on their emotions and breaking the law to rescue him made them no better than villains.[2]

Tsuyu worries about All Might

Tsuyu showing a rare moment of emotional weakness.

Tsuyu has proven to be very observant of others, as she was the first to note the similarities between Izuku Midoriya and All Might’s Quirk. Tsuyu is noticeably calm and collected, being able to stay levelheaded in stressful situations. Smart and studious, Tsuyu is known for having great judgment and is rarely moved by emotion. Because of this, Recovery Girl describes her as a "perfect pillar of emotional support" capable of leading others.[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, creeping them out in the process. Tsuyu has a habit of tipping her finger against her mouth while speaking, pondering or showing curiosity. She also says "ribbit", emulating a frog's croaking, 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 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 she’s paired with, most notably when she and Ochaco Uraraka, combined their powers to create a unison Super Move known as "Meteor Fafrotskies". According to Recovery Girl, 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 hero (formerly No. 9). Even with her stamina drained, Tsuyu, alongside Ochaco and Nejire, were still able to effectively aid Ryukyu against Rikiya Katsukame, one of the Eight Expendables. During the Joint Training, Tsuyu had enough 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 speed. She was even capable of using her incredible leg strength to not only break through Hiryu Rin's scale armor, but also send him flying into the distance, causing Hiryu to collide with Jurota (who was being subdued by Hitoshi Shinso), thus defeating the two Class 1-B students, and securing victory for their team.

Keen Intellect: Tsuyu has proven to be very intelligent, and analytical as seen in the U.S.J. Arc where she noticed the Quirk similarities between Izuku Midoriya and All Might. During the U.S.J. Incident, Tsuyu deduced, from the League of Villains' plan to kill All Might, that they may have a way to do so. This turned out to be a correct hypothesis, as it was later confirmed in the form of a Nomu. With her level-headedness and analytical skills, Tsuyu successfully helped Izuku and Minoru Mineta escape from the water villains that surrounded the trinity in the Flood Zone. Tsuyu also scored 6th place in the mid-terms, showcasing her proficiency in academics.[4] For the Final Exams, Tsuyu was paired with Fumikage to battle against Ectoplasm, one of the most formidable teachers and Pro Heroes at U.A. High School, and there was difficulty due to Ectoplasm’s replicative abilities. When it appeared that Tsuyu and Fumikage were about to lose, Tsuyu, avoiding Ectoplasm's attention, was able to take advantage of Dark Shadow's long-ranged abilities that Fumikage used to close the distance between him and the replicating Pro Hero, in order to discreetly handcuff the latter, claiming victory for both her and Fumikage. During the Joint Training, she took advantage of Jurota Shishida's enhanced sense of smell by coating her teammates, Denki and Hitoshi, in mucus so that their scents still be the same as her's, thus making the trio indiscernible to Jurota.


Frog ( Kaeru?): Tsuyu's Quirk allows her to do anything a frog can do such as: hopping long distances, jumping, sticking to walls, extending her tongue, which can lift an entire person's body up to a maximum of 20 meters, ejecting / washing her stomach, secreting toxic, sticky liquid, and camouflaging herself. However, when she is in cold environments for too long, she is unable to use her Quirk and goes into hibernation.

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.

Tsuyu Prototype Design

Tsuyu Asui's preliminary design.

  • Tsuyu's preliminary design was less frog-like and more human in appearance, with smaller eyes and mouth. She was also supposed to be more downbeat.
    • Tsuyu was also originally conceived as a male character but was turned into a female because the class lacked girls at the time. She shares this aspect with Toru Hagakure.
  • Tsuyu's name contains the kanji for frog (?), puff (?), and Japan's rainy and humid climate (梅雨?), the latter which is the climate during the toad's egg-laying season.
  • Tsuyu's known U.A. data is as follows:

    • Additionally, Tsuyu's birthday is a day after Chika's (February 11), both have the kanji for rain (雨) in their names, and both seem to be related to frogs (in World Trigger's system, Chika's zodiac sign is Rana, the frog).
  • With her birthday taking place in February, Tsuyu is the second youngest student in Class 1-A, as everyone was 15 when they started U.A.'s school year in early April.


  • (To her classmates, regarding the rescue mission for Katsuki Bakugo) "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!"[6]
  • (To Himiko Toga, regarding being called by her first name) "Cut it out! Only people who are my friends can call me that!"[7]
