Top 10 Female Anime Characters with Breasts So Big They Practically Have Macromastia

Macromastia, or breast hypertrophy, is a condition where a women's breasts grow to massive size. It was first described in 1648 and some doctors believe it occurs when a woman's breasts become big enough to account for 3% of their body weight. One of the most famous incidents of macromastia is that of Punky Brewster actress Soleil Moon Frye where her breasts grew like crazy in her mid-teens. Many women and girls who develop macromastia aren't exactly happy with what mother nature gave them. But in the world of anime, it's a very different story.

While drawing anime characters can be difficult and take time to practice, breasts are one of the easiest parts to draw. In fact, probably the hardest part of drawing breasts is practicing self-control. And because anime isn't just for children, it's surprisingly easy to go overboard when drawing these parts. And that has resulted in many female anime characters with macromastia-esque breasts. So here are ten such anime characters to start with and I'm counting on the community to add more.
The Top Ten
Tomo Yamanobe - Seikon No Qwaser

Also known as Qwaser of Stigmata, this show has a pretty bonkers premise that I'd rather not discuss. What blows my mind about this series is that it has a Canadian Home Video Rating of only 14+, meaning minors as young as 14 years old in Canada can either buy or rent it. This is definitely one anime you shouldn't let your parents catch you watching, regardless of the age rating.

While Tomo might not have the largest breasts in the series, her role as a main character definitely sets the tone for the anime.

Komoe Harumachi - Eiken

While there are numerous overly busty gals in Eiken, Komoe Harumachi easily stands above the rest. What makes her noteworthy is that she not only has the largest breasts in the anime and the second largest in the manga, but she's also the youngest member of the Eiken club. It's amazing how she's able to do anything when her breasts are practically as big as her whole body.

Milky - Interspecies Reviewers

This is probably one of the most controversial anime ever because it involves a quartet of men as they visit various brothels designed for whatever sexual fetish men desire. Two of the most well-known girls are Milky and Ginny, female minotaurs with massive breasts who work at a brothel called The Dairy Farm. If by some chance this anime gets a second season, I would love to see more of these girls.

Cattleya - Queen’s Blade

When it comes to sexual innuendo, Queen's Blade pulls no punches. This is made clear in the first episode when Leina and Melona cross paths. One of the most notable female characters is Cattleya, who has the largest breasts in the series. Despite her appearance, Cattleya is surprisingly strong and can wield a giant sword very easily. In fact, her breasts are so big, her son Lana could probably fit inside one.

Cattleya is at the top of the list when it comes to mind-blowing figures.

Ilulu - Miss Kobayashi's Dragon Maid

I thought Quetzalcoatl's human form had massive breasts. But when Season 2 debuted, Ilulu easily usurped her crown as the bustiest gal in the series. In fact, there was a bit of controversy surrounding her character when the second season was announced, mainly because of how her massive chest contrasts with her small stature.

Shizuka Marikawa - Highschool of the Dead Shizuka Marikawa is a fictional character in the manga and anime series Highschool of the Dead. She is portrayed as the high school nurse who escapes the zombie outbreak alongside a group of students. Despite her air-headed demeanor, she is a reliable adult figure in the group and provides essential... read more

Highschool of the Dead is what some people call "The Walking Dead" if it were an anime. A group of Japanese high school students and the school's nurse experience a zombie outbreak and must band together in order to survive. You can probably tell that Shizuka is the school's nurse. Even though it's part horror, there's usually a heavy dose of sexual innuendo. For example, in one chapter of the manga where the group takes shelter in a mall, they hide their weapons in a bra bin - classic.

Despite the premise, this was actually pretty solid. It was a real shame when one of the creators, Daisuke Sato, passed away on March 22, 2017, from heart disease. While it can still technically continue, it probably won't follow what Daisuke had in mind.

Meiko Shiraki - Prison School

As the second in command of the Underground Student Council at Hachimitsu Academy, Meiko is also the strongest student and proficient in martial arts. Unlike most anime girls who have macromastia purely for eye candy, Meiko's large breasts are probably what drove her to become who she is today because of how she was bullied over them.

Two recurring running gags are her wardrobe malfunctions and how she sweats profusely when working out or in a state of fear.

Aki Nijou -Maken-Ki!

Maken-Ki! is the story about a male student enrolled in a co-ed school that used to be all female. One of the most notable members of the faculty is the nurse, Aki Nijou. In a flashback in one episode, her breasts started to really develop when she was only 12 years old. Of course, her teenage years have got nothing on how attractive she is now.

Mizuki Tachibana - Gravion

Gravion is one of the earliest ecchi animes, premiering in 2002 and getting a sequel in 2004. One of the more prominent characters is Mizuki Tachibana, the only female adult member of Earthgertz, and it definitely shows. In fact, I once saw an ad in a magazine for this anime that boasted "Gravity Defying Breasts" as part of it.

Here's a fun fact: in the "Angel Blade Punish" anime, there's a character named Hazuki Tachibana who looks exactly like Mizuki. I guess changing one part of the name was enough to avoid getting into copyright-related trouble.

Akeno Himejima - High School DxD

Best girl. Beautiful, cooks well, lovely, strong, cute, sexy, tall, all.

I want her. She is unmatched in size and incredibly skilled.

The Newcomers

? Karin Nanase - In/Spectre

Karin was a gravure idol in life before a steel beam landed on her face and killed her. Now, as a ghost that looks like her - with the obvious difference being the smashed face - she haunts the area and has the ability to wield a steel beam with ease.

? Hana Uzaki - Uzaki-chan Wants to Hang Out!
The Contenders
Tsunade - Naruto Tsunade is a fictional character from the Naruto manga and anime franchise. She was created by Masashi Kishimoto and is one of the Legendary Sannin. Tsunade is known for her medical skills, superhuman strength, and her leadership as the Fifth Hokage of the Hidden Leaf Village.

Hokage! Why are your boobs so big?

Nami - One Piece Nami is a fictional character in the One Piece franchise created by Eiichiro Oda. She is the navigator of the Straw Hat Pirates and is known for her skills in cartography, navigation, and theft. Her character design was inspired by Ann and Silk, two characters from Oda's earlier work Romance Dawn.

Nami's breasts were actually pretty small when the series started, but now they're huge. If 4Kids found out about how big her breasts would become, it wouldn't have been pretty for the fans.

Rangiku Matsumoto - Bleach Rangiku Matsumoto is a fictional character in the Bleach manga series and its adaptations created by Tite Kubo. She serves as the lieutenant of the 10th Division in the Gotei 13 under Captain Tōshirō Hitsugaya. Rangiku is known for her laid-back personality and powerful spiritual pressure.

I don't know why I didn't add her when making this list. When it comes to women with macromastia from Bleach, this gal is usually the first one that comes to mind.

Murasaki - Senran Kagura: Shinovi Master

Ever since the series made its debut on the 3DS, girls with large breasts have basically been Senran Kagura's trademark. This is mainly because series creator Kenichiro Takagi thought of breasts in 30 seconds when he asked himself what people would want to see in 3D. In the first installment, it was difficult to determine which gal had the largest breasts. However, when Senran Kagura: Shinovi Versus was released, Murasaki's 105cm bust settled the debate. To date, she has the largest breasts in the series.

Boa Hancock - One Piece Hancock is a tall, slender woman with long black hair that extends past her waist, pale skin, a high forehead, and dark brown eyes framed by long, voluminous lashes. She has a narrow waist and a large bust, with official measurements of B111-W61-H91 cm (43.7″ - 24.0″ - 35.8″), making her a J-cup... read more

Boa Hancock is the love of my life. And I respect and love her with all of my heart.

She really is actually and truly a kind, caring, and loving woman. It was her past and what those sick bastards, the Celestial Dragons, did to her and her sisters, Sandersonia and Marigold, that made Boa Hancock very cold, closed off, and unable to trust anyone. What she and her sisters went through at the hands of those monsters was horrible.

So yes, of course, I am going to vote for the love of my life, Boa Hancock.

I am speechless about her. Hers is truly mind-blowing.

Centorea Shianus - Monster Musume

I watch this anime and her breasts are so big.

Hinata Hyuga - Naruto Hinata Hyuga is a fictional character in the anime and manga franchise Naruto, created by Masashi Kishimoto. She is a member of the Hyuga clan and known for her gentle personality and Byakugan ability. Over the series, she grows from a shy ninja into a confident fighter and later marries Naruto Uzumaki... read more

Lady J - Valkyrie Drive: Mermaid
Orihime Inoue - Bleach Orihime Inoue is a fictional character in the Bleach manga series and its adaptations, created by Tite Kubo. She is a classmate of the main protagonist, Ichigo Kurosaki, and possesses unique spiritual powers, including healing and shield creation. Orihime plays a significant role throughout the series,... read more

This might surprise non-fans, but there's a two-year time skip where her breasts actually get bigger. She starts at 36H and after the time skip she's at 40I.

I'll make a strong statement and say that the author has never seen real breasts in his whole life.

Nene Fujinoki - Hajimete no Gal
Hotaru Shidare - Dagashi Kashi
Erza Scarlet - Fairy Tale Erza Scarlet is an S-Class Mage from the infamous magic guild Fairy Tail. Erza starts off as a lone wolf and stays loyal to following the rules.
