If you are looking for anime characters born in September, start with your exact day first, then check whether the birthday is officially sourced or only repeated in fan databases. September has several easy matches from big series, including Naruto, One Piece, Demon Slayer, Bleach, and My Hero Academia, but not every online birthday entry is equally reliable.
Anime Characters Born in September by Date
The most practical way to use September anime birthdays is by date, not by franchise. If your goal is a birthday match, fan post, profile check, or themed character pick, the day of the month matters more than scrolling through a long mixed list.
September 1 to September 10 birthdays
Early September has some of the strongest quick matches. Boa Hancock from One Piece is commonly listed on September 2, while September 3 is often tied to Orihime Inoue from Bleach and Zenitsu Agatsuma from Demon Slayer. Crocodile from One Piece is widely listed on September 4, and Hange Zoë from Attack on Titan is commonly associated with September 5.
September 11 to September 20 birthdays
Mid-September is especially popular because September 15 often appears with two major names: Kakashi Hatake from Naruto and Obanai Iguro from Demon Slayer. Yami Sukehiro from Black Clover is also commonly listed on September 17.
If you are making a birthday post for fun, these matches are usually strong enough to be recognizable. If you are writing a reference page or quiz answer, check the character's official profile source before presenting the date as confirmed.
September 21 to September 30 birthdays
Late September gives you a good mix of character types. Shikamaru Nara from Naruto is commonly listed on September 21, Kuzan/Aokiji from One Piece is often placed on the same date, and Momo Yaoyorozu from My Hero Academia is widely associated with September 23.
Popular Anime Characters With September Birthdays
Popularity matters because most people are not trying to memorize every minor profile date. They want characters they can recognize, share, or compare with friends. For that, the strongest September birthdays usually come from long-running shonen series, school-based casts, and fantasy or supernatural anime with active fandoms.
There are two different use cases here. For a casual birthday match, a popular repeated entry may be enough. For a factual database, wiki edit, or published post, popularity should never replace source checking.
September-born shonen anime characters
Shonen series dominate September birthday searches because their casts are large, profile details are often documented, and fans keep celebrating character dates every year. The biggest examples include Kakashi Hatake and Shikamaru Nara from Naruto, Boa Hancock and Crocodile from One Piece, Orihime Inoue and Gin Ichimaru from Bleach, Zenitsu Agatsuma and Obanai Iguro from Demon Slayer, and Yami Sukehiro from Black Clover.
September-born school anime characters
School anime birthdays feel more personal because birthdays fit naturally into classroom settings, clubs, friendships, and seasonal events. Momo Yaoyorozu from My Hero Academia is the most obvious September example here because she is both a superhero character and a student in Class 1-A.
- For school-action fans: Momo is a clean match because her series keeps student identity central.
- For sports anime fans: Koutarou Bokuto from Haikyu!! is often included in September birthday searches, but verify the date from a reliable profile source.
- For romance or character-profile fans: Megumi Katou from Saekano and Amu Hinamori from Shugo Chara! often appear in compiled birthday references.
September-born fantasy anime characters
Fantasy and supernatural characters make September lists more varied. Zenitsu and Obanai from Demon Slayer are the strongest examples, while Hange Zoë from Attack on Titan often appears in September birthday roundups, even though the series sits closer to dark military fantasy than classic magic-world anime.
These birthdays are useful when you want a character match with a stronger story identity. A casual fan might pick Zenitsu because the date is easy to recognize, while someone who likes intense side characters may prefer Obanai or Hange.
September Anime Characters by Series
Searching by series is better when you already know which anime you care about. A Naruto fan may not need a full monthly database; they may only want to know whether any shinobi share their date. The same is true for One Piece, Demon Slayer, or My Hero Academia.
Naruto characters born in September
Naruto has two of the most searched September birthdays: Kakashi Hatake on September 15 and Shikamaru Nara on September 21. Both are strong matches because they are major characters with long-term visibility across the franchise.
Kakashi is the better match if you want a recognizable mentor figure. Shikamaru is the better match if you like tactical, low-drama characters whose appeal grows over time.
One Piece characters born in September
One Piece has several commonly listed September birthdays, including Boa Hancock on September 2, Crocodile on September 4, and Kuzan/Aokiji on September 21. The series appears in birthday searches so often because its cast is huge and its character profiles are heavily discussed by fans.
When checking One Piece birthdays, pay attention to whether the source separates official profile information from fan-maintained compilations. The franchise has many characters, so unsourced lists can easily mix solid entries with weaker ones.
Demon Slayer characters born in September
The main Demon Slayer September birthdays to know are Zenitsu Agatsuma on September 3 and Obanai Iguro on September 15. Zenitsu is the easier match for general fans because he is one of the most recognizable main cast members, while Obanai is especially relevant for readers tracking the Hashira.
My Hero Academia and other series characters
My Hero Academia contributes Momo Yaoyorozu, commonly listed on September 23. She is a strong late-month match because she is a central student character rather than a small background name.
Other commonly mentioned September characters include Hange Zoë from Attack on Titan, Gin Ichimaru from Bleach, Megumi Katou from Saekano, and Amu Hinamori from Shugo Chara!. This is where your own taste matters: if you are choosing a birthday twin for fun, a niche character from a favorite series may feel more satisfying than a famous character from a show you barely watch.
Which Anime Characters Share Your September Birthday?
To find your match, start with the exact month and day, then narrow the results by series and source quality. The fastest answer is not always the best one, especially when a character appears only on one unsourced birthday page.
Characters born on the same date
Several September dates are shared by more than one popular character. September 3 is often associated with Orihime Inoue and Zenitsu Agatsuma. September 15 is commonly tied to Kakashi Hatake and Obanai Iguro. September 21 often appears with Shikamaru Nara and Aokiji.
Shared dates are the best part of birthday matching because they give you a choice. If one match does not fit your taste, another character on the same day might.
Popular characters by birthday match
A popular birthday match is easier to celebrate because other fans are already posting art, edits, and character tributes on that date. Kakashi, Shikamaru, Boa Hancock, Zenitsu, Orihime, and Momo are all stronger choices if you want a birthday twin people will recognize quickly.
Finding birthdays across different anime series
Use a simple checking order so you do not get stuck in endless birthday pages:
- Search the exact date first. "September 15 anime birthdays" is more useful than a full-month search.
- Write down repeated names. If the same character appears across several reliable pages, it is worth checking further.
- Look for the original source. Databooks, manga extras, official websites, and publisher materials are stronger than unsourced lists.
- Mark uncertain entries. Use "commonly listed" or "unconfirmed" when the source is unclear.
Are Anime Character Birthdays Official?
Some anime character birthdays are official, and some are simply fandom-compiled. The difference is important because a birthday can appear on many pages without any clear link back to the creator, publisher, manga volume, guidebook, or official profile.
Birthdays confirmed by official sources
The strongest birthday entries come from official materials such as manga volume extras, character books, guidebooks, publisher websites, franchise profile pages, or licensed game profiles. These sources often place birthdays beside other profile details like height, affiliation, age, or favorite foods, which makes the entry easier to trust.
Large franchises such as Naruto, One Piece, Bleach, and My Hero Academia are often easier to verify because their character data has been discussed and archived for years.
Fan databases and compiled lists
Fan databases are useful for finding names quickly, especially when you are searching across many series. Their weakness is sourcing: some cite official materials clearly, while others repeat dates without showing where they came from.
- Good use: discovering possible September birthday matches.
- Risky use: treating an unsourced entry as confirmed.
- Best check: compare the database entry with an official profile or a well-cited franchise page.
Unconfirmed or missing birthday information
Many anime characters have no confirmed birthday at all. Some creators never assign exact dates, and some series focus more on story, setting, or powers than profile details.
When a birthday cannot be traced to a dependable source, it is better to leave it as unknown than to force a match. That is especially true if you are making something other people may use as a reference.
Conclusion
September is a good month for anime birthday matches because it includes recognizable names across action, school, fantasy, and long-running shonen series. Start with your exact date, enjoy the fun matches, and only call a birthday official when you can trace it to a dependable source.
