One Punch Man is a series where having incredible strength is just the norm. But having power does not mean that the character is going to have depth, especially when it comes to female characters in this story. While the main narrative primarily focuses on Saitama, Genos, and the S-Class heroes, the series has never shied away from introducing some overpowered women.

From Fubuki, the commanding leader of the Blizzard Group, to Tatsumaki, the psychic powerhouse capable of tearing through entire cities, One Punch Man has offered glimpses of complex, skilled women making their mark in a hero society dominated by testosterone and showmanship. Among them stands out Mizuki, a B-rank hero who was a former national-level track and field champion and turned into a hero who uses her expertise on the battlefield.

Although her ranking is on the lower side, Mizuki has gained traction among fans and readers for her strength, resolve, and personality. She proved her worth as a hero during the Monster Association Arc in the Human Monster Saga, when she took down monstrous threats and even managed to inspire others.

Another interesting aspect about her is how her character is designed. It is undeniable that Mizuki's design plays into traditional fanservice aesthetics. In One Punch Man, she’s often depicted mid-action with intense physicality, lunging, leaping, or twisting in undeniably eye-catching ways.

While this makes sense because she has an athletic build, but on the side it also raises questions about whether her design was meant more to appeal visually than narratively. While her appearance may attract attention, it’s her courage and determination that truly earn her fans’ respect.

In the story, she is shown to have a cheerful personality that stems from her past. As she is an athlete turned hero, all her mission is treated with readiness. Mizuki is ready to dive into action and is optimistic about them. Even when facing overwhelming danger. Despite being younger and less experienced, she shows maturity in how she handles danger and setbacks.

Captain Mizuki isn’t a lone wolf. She thrives on teamwork and places high value on support roles. Her interactions with Superalloy Darkshine show a deep admiration and willingness to learn, while her trust in Child Emperor’s leadership during the Monster Association raid reveals her respect for hierarchy and coordination.

Finally, her fighting style is what makes her different from others. Rather than relying on supernatural abilities or complex gadgets, she turns her athletic gear into lethal tools and her training into deadly precision. She also uses traditional grappling to subdue enemies on the ground, showcasing her versatility.


Mizuki’s strength and her future in One Punch Man

Mizuki's brief yet impactful appearance in the Monster Association Arc has left fans hoping for more. While she may not have the psychic power of Tatsumaki or the command of Fubuki, Mizuki represents something equally valuable: resilience, athleticism, and courage. Her unique sports-inspired fighting style, her ability to improvise, and her genuine heroism make her a character with tremendous potential.

She’s also a refreshing counter to the hyper-masculine or overly powerful aesthetic that dominates the series. In One Punch Man, Mizuki is grounded. She doesn’t fly or shoot lasers. She jumps, she throws, she grapples, and she gets back up when knocked down.


In conclusion, Mizuki in One Punch Man is one of those heroes who dive first and then think later. Even though she is a B-Rank hero, it has not stopped her from fulfilling her duties, and being a former athlete, she understands the meaning of what it means to be a superhero without any superpowers. Yes, her character design fits the fanservice mold, but her character breaks free of that limitation. She’s strong, relatable, and undeniably heroic.
