Tsuyu Asui is a character from the My Hero Academia anime and manga.

A young girl whose strange appearance is caused by her Quirk, "Frog", which allows her to do pretty much anything a frog can, including jump very long distances, swim with extreme agility and extend her tongue like a flexible steel cable. She is calm and level-headed even in the most stressful situations, and she tends to bluntly say whatever is on her mind.

In the XP4 fics, Tsuyu debuted in XP4 Heroes Coalition - Kick-Off!.

In the AWA fics, Tsuyu is a student at the AWA Academy and is part of Class 6.


Tsuyu is a short girl with a frog-like appearance. She has long, dark sea-green hair which she ties in a bow on her back. She has very wide eyes with pure black irises and distinctive lower eyelashes. Like a frog, she has a wide mouth.

Her Hero costume is a green and black skintight suit with yellow linings which imitate a frog's skin markings. She also wears goggles, gloves, and boots with a frog-like design. Despite her boots being shaped like frog feet, she does have ten toes.


Tsuyu is a straightforward and laid-back individual who always says what's on her mind and what she thinks about others. She prefers to be called "Tsu", but has stated she only wants people she views as friends to refer to her as such. She commonly refers to everyone with the honorific "-chan". She has proven to be very observant, as she was the first to note the similarities between Izuku and All Might's Quirks.

Tsuyu is noticeably calm and collected, being able to stay levelheaded in stressful situations. Smart and studious, Tsuyu is known for having great judgement and is rarely moved by emotion. She might disapprove rash decisions from her classmates, but she doesn't always act against said rashness, which is something she deeply regretted after the kidnapping of Katsuki Bakugo and Izuku Midoriya's decision to rescue him. Recovery Girldescribes her as the "perfect pillar of emotional support".

Her usual expression consists of a vacant stare, which makes reading her thoughts and emotions difficult for those around her. Tsuyu has a habit of tipping her finger against her mouth while speaking or pondering. She also says "ribbit" as a replacement for many of her single word replies.

XP4 Fanfics

Tsuyu is a member of the Heroes Coalitions and is part of The Mighty Never Kneel. She also attends the Vanguard Academy as a student.

XP4 Heroes Coalition - Kick-Off!

In Chapter 6, Tsuyu, alongside her team, The Mighty Never Kneel and another team called The Flaming Honor, are seen in Magnum City taking on a group of Emotionless and successfully defeated them.


Keen Intellect: Tsuyu has proven to be very intelligent as seen in Unforeseen Simulation Joint Arc where she noticed similarities of Izuku and All Might's quirk. She also deduced from the League of Villains' plan to kill All Might that may have a way to do so, which was confirmed in the form of Nomu. Tsuyu also scored sixth in the mid-terms, showing her skill in academics.


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 to a maximum of 20 meters; ejecting/washing her stomach and secreting toxic sticky liquid, and camouflage. However, when she is in cold environments for too long, she is unable to use her quirk.

    • 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.
