Chainsaw Man does not have a complete official birthday database. The strongest published age information confirms Denji as 16 at the beginning of Part 1 and later 17, Kobeni Higashiyama as 20, and Hirokazu Arai as 22. Most other characters, including Aki, Power, Makima, Himeno, Kishibe, Reze, Asa, Yoshida, and Nayuta, have no officially confirmed numerical age in the sources reviewed. No official month-and-day birthdays have been published for the principal cast.
Spoiler warning: This guide discusses character identities, devil and fiend status, transformations, deaths, and Part 2 developments.
Chainsaw Man character statistics at a glance
This guide uses the core Part 1 cast identified by the official Shueisha series material: Denji, Pochita, Makima, Aki Hayakawa, Power, and Himeno. It also includes recurring Public Safety characters Kobeni Higashiyama, Hirokazu Arai, and Kishibe, plus Reze because of her importance to Denji’s story and the official Reze Arc movie material. The final section adds major Part 2 characters.
How to read the table: Confirmed numerical ages come from an official profile or a clear in-story statement. A canon age progression means the character’s age is confirmed at one point and changes later. Qualitative descriptions such as adult, student, senior, veteran, or child-aged are not being converted into invented numbers.

| Character | Age | Height | Birthday | What is actually supported |
|---|---|---|---|---|
| Denji / Chainsaw Man | 16 at the start of Part 1; later 17 | 173 cm* | Not officially specified | His age progression is established by the story. The height is reported exhibition-setting data for Denji, not a measurement printed in a manga panel. |
| Pochita | Not applicable | Not officially specified | Not applicable | Pochita is a devil who becomes Denji’s heart, not a human child with a documented birth date. |
| Makima / Control Devil | Exact human-equivalent age unknown | 168 cm* | Not officially specified | She appears as an adult woman, but no confirmed numerical age has been published. The height is reported exhibition-setting data. |
| Aki Hayakawa | Exact age unknown | 182 cm* | Not officially specified | Aki is clearly older than Denji and is his senior in Public Safety, but seniority does not establish a precise age. |
| Power / Blood Fiend | Exact age unknown | 170 cm* | Not officially specified | Power occupies a human body but is a Blood Fiend. Fiend existence is not presented as ordinary human aging, so a human birthday is not established. |
| Himeno | Exact age unknown; often cautiously characterized as being in her 20s | 175 cm* | Not officially specified | The age-in-her-20s description is a secondary characterization, not a precise official number. The height is reported exhibition-setting data. |
| Kobeni Higashiyama | 20 in the Part 1 anime character profile | 155 cm* | Not officially specified | One of the clearest numerical age entries. The official profile calls her a 20-year-old rookie; it does not establish a later timeline age. |
| Hirokazu Arai | 22 in the Part 1 anime character profile | Not officially confirmed in reviewed sources | Not officially specified | The official profile identifies Arai as a 22-year-old rookie. No reliable official height or birthday was found in the reviewed sources. |
| Kishibe | Exact age unknown | Not officially confirmed in reviewed sources | Not officially specified | He is a veteran Public Safety captain. Calling him middle-aged or assigning a specific number goes beyond the available evidence. |
| Reze | Exact age unknown | Not officially confirmed in reviewed sources | Not officially specified | The official Reze Arc material presents her as a mysterious girl Denji meets while sheltering from rain and identifies her as a Café Nido worker, but gives no numerical age or height. |
| Asa Mitaka | High-school age; exact number not officially confirmed in reviewed primary sources | Not officially specified | Not officially specified | Her student status supports a broad age category, not a precise figure. |
| Yoru / War Devil | Not applicable as a human age | Not officially specified | Not applicable | Yoru is a devil sharing Asa’s body. Asa’s presumed human age should not be assigned to Yoru as though they were the same person. |
| Nayuta | Child-aged appearance; exact numerical age unknown | Not officially specified | Not officially specified | Her appearance and narrative role establish a child-like presentation, but not a verified calendar age or birthday. |
| Hirofumi Yoshida | Exact age not officially specified | Not officially specified | Not officially specified | He is portrayed as a student and young devil hunter. Popular fan estimates should not be presented as canon. |
*The six height figures marked with an asterisk are commonly reported from the 2023 TV Animation Chainsaw Man Exhibition’s character-setting material. The exhibition’s public webpage documents the event and its setting displays but does not expose a complete text height chart on the page itself. These numbers should therefore be described as reported exhibition-setting data, not as measurements explicitly printed in the manga.
Which Chainsaw Man ages are officially confirmed?
Denji: 16 at the beginning, then 17
Denji begins the story as a 16-year-old boy living in extreme poverty and working as a devil hunter to repay his father’s debt. The story later establishes that he reaches 17. That makes Denji a case of canon age progression: saying only 16 or only 17 is incomplete unless the point in the timeline is specified.
Denji’s transformation into Chainsaw Man does not create a separate human age. The human teenager and the devil-human hybrid are part of the same character, although the transformed form should not be treated as a normal human body when comparing physical appearance.
Kobeni Higashiyama: 20
Kobeni is explicitly described as 20 in the official Part 1 anime character profile. This is a confirmed numerical age, but it should be tied to the profile’s Part 1 context rather than casually projected onto every later point in the series.

Hirokazu Arai: 22
Arai’s official Part 1 anime profile gives him an age of 22 and describes him as a rookie. His confirmed age also helps explain why a Public Safety rookie is not necessarily a teenager. The same reviewed sources do not provide a confirmed height or birthday.
Why Aki, Power, Makima, and the others have no exact age
Chainsaw Man frequently communicates age through role and experience rather than birth-date statistics. Aki is Denji’s senior, Himeno is an experienced partner, Kishibe is a veteran captain, and Makima presents as an adult woman. Those descriptions establish relative position or appearance, but they do not supply a numerical age.
There is an additional complication: not every major character is an ordinary human. Devils and fiends do not automatically have human-style birthdays or aging timelines. A character may have a human appearance, inhabit a human body, or interact with humans without having a canon birth date that can be placed on a calendar.
- Makima: Her adult appearance is clear, but her exact human-equivalent age is not.
- Aki: Being Denji’s Public Safety senior proves that he is older in the relevant professional hierarchy, not that he is a particular number of years older.
- Power: She is a Blood Fiend, so her apparent body age should not be treated as a verified human age.
- Himeno: Secondary references often place her in her 20s, but the evidence does not justify a precise number.
- Kishibe: His veteran status and appearance support a mature-adult description, not a confirmed age.
- Reze: She is presented as a young woman and a capable covert combatant, but the official Reze Arc profile does not give a number.
Reported character heights from the anime exhibition
The most useful height figures available for the Part 1 group are the measurements associated with the 2023 TV Animation Chainsaw Man Exhibition:
Rank #3
- 50 SET 4x6 INCH HIGH QUALITY PICTURES anime manga wall decor, anime poster pack, poster set
- TEEN ROOM DECOR: trendy woonkit anime posters for room aesthetic, anime posters, manga panels for wall
- BEAUTIFUL ANIME MANGA PICTURES: great for teen bedroom decor, manga wall collage and anime stuff

- THOUGHTFUL GIFT - high picture quality and beautiful packaging makes a perfect anime posters gift
| Character | Reported height |
|---|---|
| Aki Hayakawa | 182 cm |
| Himeno | 175 cm |
| Denji | 173 cm |
| Power | 170 cm |
| Makima | 168 cm |
| Kobeni Higashiyama | 155 cm |
These figures are best used as anime-setting references. They are not a universal answer to every height comparison in the manga, and they should not be extended to Arai, Kishibe, Reze, Asa, Yoru, Nayuta, or Yoshida when the reviewed official material does not provide a corresponding number. Fan-made charts may measure panels or compare artwork, but those calculations are estimates rather than official specifications.
Chainsaw Man birthdays: why the dates online are unreliable
No official month-and-day birthday has been published for the principal cast in the sources reviewed. That includes Denji, Aki, Power, Makima, Himeno, Kobeni, Arai, Kishibe, Reze, Asa, Nayuta, and Yoshida. Pochita and Yoru are better marked as not applicable because they are devils rather than ordinary human characters.
Some scenes involve birthday-like celebrations or discussions about a character’s age, but narrative context is not the same as a disclosed calendar date. In particular, a scene that establishes Denji’s age or shows someone celebrating him does not automatically establish January, March, or any other month-and-day birthday.
The accurate wording is No official month-and-day birthday has been published for this character in the sources reviewed. Saying that a character has no birthday goes further than the evidence allows. Fan databases, astrology posts, social-media graphics, and repeated wiki entries are not sufficient to turn an unverified date into canon.

Part 2 character ages and identities
Part 2 adds several characters whose statistics are especially easy to misreport because human age and devil identity overlap.
Asa Mitaka
Asa is a high-school student, so “high-school age” is the most defensible description. The reviewed primary sources do not confirm an exact number, height, or birthday. A fan estimate should remain labeled as speculation.
Yoru
Yoru is the War Devil and shares Asa’s body. Yoru should not be assigned Asa’s presumed school-age number. As a devil, Yoru does not have a confirmed human-style age or birthday in the reviewed material.
Nayuta
Nayuta has a child-aged appearance and occupies a significant role in the Part 2 story, but the reviewed primary sources do not provide a verified numerical age, height, or calendar birthday. Appearance is evidence of presentation, not proof of an exact age.

Hirofumi Yoshida
Yoshida is portrayed as a student and young devil hunter. Those labels support a qualitative description, but no exact official age, height, or birthday was confirmed in the sources reviewed. Numbers commonly repeated online should not be placed in a canon table without a primary source.
Evidence standard used for this guide
- Official character profiles: The official anime character page identifies the Part 1 cast and explicitly gives Kobeni’s age as 20 and Arai’s as 22.
- Story statements: The manga establishes Denji’s age at the start and later shows his progression to 17.
- Official series and movie pages: Shueisha’s series material identifies the original principal cast, while the official Reze Arc site identifies Reze’s role and introduction without giving a numerical age.
- Exhibition-derived setting data: The six listed heights are reported from the 2023 TV Animation Chainsaw Man Exhibition materials. They are presented separately from manga-published facts because the public exhibition webpage does not display a complete text chart.
- Fan estimates: These are excluded from the factual table unless clearly identified as speculation. A repeated birthday or height claim does not become official through repetition.
This evidence hierarchy explains why the table contains many entries marked unknown. “Unknown” is not a missing guess; it is the most accurate answer when the creator or an official publication has not supplied the number.
Frequently Asked Questions
Does Makima have an official age?
No exact numerical age has been officially confirmed in the sources reviewed. Makima appears as an adult woman, but appearance is not a verified age.

No official month-and-day birthday has been published for Denji in the sources reviewed. The story establishes his age at different points, but age context does not establish a calendar date.
Are the Chainsaw Man height numbers official?
The commonly reported figures for Denji, Aki, Power, Makima, Himeno, and Kobeni are associated with the 2023 TV Animation Chainsaw Man Exhibition’s setting materials. They should be labeled reported exhibition-setting data rather than manga-printed measurements.
Is Power the same age as the human body she uses?
That cannot be confirmed. Power is a Blood Fiend, and fiend aging is not treated like ordinary human aging. The series does not provide her a verified human-style age or birthday.
The Bottom Line
Bottom line: The only firm numerical ages in this guide are Denji’s 16-to-17 progression, Kobeni’s 20, and Arai’s 22. Six Part 1 height figures are reported from exhibition setting material, while most other heights remain unconfirmed. No official month-and-day birthday has been published for the principal cast reviewed, so fan birthday charts should not be presented as canon.
