Let’s face it, anime often defies the laws of physics, and nowhere is that more apparent than with some of its characters' ridiculous chest sizes!

Whether it’s for fanservice, humor, or even as part of the plot, these waifus have earned a special place in our hearts (and probably a visit to a chiropractor). So, without further ado, here’s the ultimate ranking of the biggest anime boobs, where size really does matter! Ready to meet the queens of anime busts? Let’s dive in!

10. Aki Nijou (Maken-Ki!) – 103 cm, K Cup

Aki Nijou is the classic “big-breasted sensei” who always manages to get into awkward, fanservice-heavy situations. With a bust of 103 cm and a K-cup, she’s hard to ignore—especially when the plot keeps throwing her chest in our faces! Aki is the kind of teacher who’s always trying to maintain her dignity, but let’s be real, Maken-Ki isn’t exactly known for its subtlety!

9. Yasaka (High School DxD) – 107 cm, K Cup

Yasaka, the nine-tailed fox spirit from High School DxD, is an elegant beauty with a 107 cm bust and K-cup chest that make her hard to miss! As a powerful mythical being, she exudes regal energy—but High School DxD isn’t exactly subtle about its fanservice, and Yasaka’s figure is highlighted in almost every scene. Let’s just say, balancing nine tails and a K-cup chest takes some serious anime magic!

8. Shizuka Marikawa (Highschool of the Dead) – 108 cm, J Cup

Shizuka Marikawa is the lovable, ditzy nurse from Highschool of the Dead who’s just trying to survive the zombie apocalypse—with a J-cup chest and a 108 cm bust, of course! Let’s be honest, she’s more known for her assets than her medical skills, but that’s part of her charm. Her big heart (and even bigger bust) bring some lighthearted fun to an otherwise intense series!

7. Sariel (The Seven Heavenly Virtues) – 113 cm, L Cup

Sariel, the angel of peace from The Seven Heavenly Virtues, has a divine L-cup chest and a bust size of 113 cm. If you’ve ever wondered what heaven looks like, just take a look at Sariel’s design!

Sariel’s angelic aura and massive chest create a hilarious contrast, as her body is more of a "heavenly body" than her actual celestial duties. With an L-cup, she’s definitely carrying more than just heavenly grace.

6. Chifusa Manyuu (Manyuu Hikenchou) – 118 cm, M Cup

Chifusa Manyuu, with her 118 cm bust and M-cup, takes the concept of "powerful" breasts to a whole new level! In Manyuu Hikenchou, breast size literally determines a woman’s political power, and Chifusa’s quest to change the system makes her M-cup a symbol of revolution.

She’s fighting for the right to redistribute... breast size, in a world where bigger means better. Her chest isn’t just for show—it’s central to the plot, making Chifusa’s journey both absurd and entertaining. Who knew that breasts could be the key to toppling a social hierarchy?

5. Cattleya (Queen’s Blade) – 120 cm, N Cup

Cattleya, the warrior and blacksmith from Queen’s Blade, comes in strong with a 120 cm bust and N-cup chest. She’s a fierce fighter and a loving mother, but her enormous assets tend to steal the spotlight—especially during battle scenes where her chest is always emphasized. How does she swing that massive sword with all that extra weight? Anime physics, obviously! Cattleya’s design is both intimidating and impressive, making her one of the most iconic "big bust" characters in anime.

4. Guinea (Interspecies Reviewers) – 120 cm, R Cup

Guinea from Interspecies Reviewers has an R-cup and a 120 cm bust that fit right in with the show’s over-the-top, anything-goes attitude. In a series that’s all about reviewing different species (and their... attributes), Guinea’s chest is the ultimate attention-grabber.

Her R-cup size is comically large, even by anime standards, and her appearance is played for laughs in nearly every scene. Interspecies Reviewers loves to push boundaries, and Guinea’s bust is the perfect example of how far the show is willing to go for shock value and fanservice.

3. Kirika Misono (Eiken) – 121 cm, O Cup

Kirika Misono from Eiken takes third place with a jaw-dropping 121 cm bust and O-cup chest that defy all logic. Eiken is notorious for its extreme fanservice, and Kirika’s breasts are practically the stars of the show! Do you recognize that GIF? This is just one of the many hilarious ones she has!

Kirika has GIFs of her boobs defying physics and gravity. Every scene she’s in seems designed to showcase her absurd proportions, with no regard for plot or reality. Her O-cup chest is so exaggerated, it’s become a meme in the anime community!

2. Ilulu (Miss Kobayashi’s Dragon Maid) – 130 cm, S Cup

Iruru, the petite dragon girl from Miss Kobayashi’s Dragon Maid, somehow manages to carry around an S-cup chest with a 130 cm bust! Her small stature and massive chest create a comical contrast, and the show uses her proportions for both fanservice and humor.

Iruru’s dragon form gives her an excuse for her wild proportions, but even then, it’s hard to ignore the fact that her S-cup chest takes up most of the screen!

1. Cathyl (Monster Musume) – 171 cm, Q Cup

Cathyl, the Minotaur from Monster Musume, takes the crown with a staggering 171 cm bust and a Q-cup chest that’s as big as her towering physique! As a Minotaur, Cathyl’s size is part of her charm, and her massive chest is a reflection of her powerful nature. Her Q-cup breasts are a constant source of fanservice, but they also emphasize her role as a dominating force in the series. She’s the ultimate big-busted waifu, and honestly, how does she even fit through doorways?!

So, which of these anime boobs are your favorite? Do you prefer any other cup size? Or are you looking for a character not on the list? Let us know in the Otaku Community, and let’s share our love (and confusion) over these wild and sexy oppai anime girls!
