If you've landed here wondering about the age of Erwin Smith in the world of demons and exorcists, you're not alone! It's a common query that often sparks from confusion between two incredibly popular anime universes. Let's clear the air right away.

Unraveling the Confusion: Erwin Smith and Blue Exorcist

To put it plainly, Erwin Smith is not a character in Blue Exorcist. Erwin Smith is a pivotal and iconic character from a completely different series: Hajime Isayama's critically acclaimed dark fantasy manga and anime, Attack on Titan. In Attack on Titan, Erwin Smith is the stoic and brilliant 13th Commander of the Survey Corps, known for his unwavering resolve and strategic genius in humanity's fight against man-eating Titans. His age is approximately 30-35 during his active service in Attack on Titan.
It's easy to mix up characters and series, especially with so many fantastic anime out there! While Erwin Smith commands legions in Attack on Titan, Blue Exorcist introduces us to a distinct world populated by demons, exorcists, and a unique struggle between humanity and the netherworld.

Discovering the World of Blue Exorcist

Blue Exorcist (Ao no Exorcist), created by Kazue Kato, is a thrilling supernatural action series that follows Rin Okumura, a seemingly ordinary teenager who discovers he is the son of Satan himself. After a tragic incident involving his adoptive father, Rin decides to defy his demonic heritage and enrolls in True Cross Academy to train as an exorcist, vowing to defeat his biological father, Satan. It's a journey filled with explosive action, deep friendships, and a constant battle against both external demons and internal struggles.
The series is renowned for its dynamic characters, intricate lore about demons and the True Cross Order, and the unique challenges Rin and his twin brother, Yukio, face as they navigate their extraordinary lineage.

Key Characters and Their Ages in Blue Exorcist

While Erwin Smith might not be part of this demonic saga, Blue Exorcist features a vibrant cast with their own compelling stories and ages that factor into their development.

Rin Okumura: The Fiery Son of Satan

The undeniable protagonist, Rin Okumura, is fifteen years old when the story begins. Born from a human woman and Satan, Rin initially lives a normal life until his demonic powers awaken. His age perfectly encapsulates the turbulent teenage years, mirroring his struggle to control his inherited powers and forge his own path as an exorcist. His journey from a rebellious youth to a determined warrior is central to the series. For a full breakdown of Rin's demonic heritage and his unique abilities, you'll want to explore our dedicated guide on his character.

Yukio Okumura: The Gifted Twin Brother

Rin's fraternal twin brother, Yukio Okumura, is also fifteen years old. Despite being Rin's twin, Yukio was born without visible demonic powers, though he carries spiritual wounds from Rin's birth that grant him constant awareness of demons. Unlike Rin, Yukio has been secretly trained as an exorcist since childhood by their adoptive father, Shiro Fujimoto, making him a prodigious genius who achieves the rank of Meister in multiple classes while still a student. His more serious and disciplined nature often contrasts with Rin's impulsiveness. To delve into Yukio's complex development and his extraordinary skills as an Exorcist, consult our comprehensive guide dedicated to his journey.

Other Notable Young Exorcists-in-Training

True Cross Academy is bustling with young students striving to become exorcists, each around Rin and Yukio's age (mid-teens) and bringing their unique talents to the fight against demons:

  • Shiemi Moriyama: A kind-hearted and gifted Tamer, she starts her journey alongside Rin, capable of cultivating powerful healing herbs with her Greenman spirit.
  • Ryuji Suguro ("Bon"): Heir to a cursed Kyoto temple, Bon is a determined and intelligent student who aims to defeat Satan. He plans to become a Meister in both Aria and Dragoon, showcasing a maturity beyond his years.
  • Renzo Shima: A seemingly carefree and jovial student from Bon's temple, Shima often provides comic relief but harbors a complex background and ambiguous loyalties.
  • Konekomaru Miwa: A brilliant strategist from the same temple as Bon and Shima, he is dedicated to achieving Meister status in Aria.
  • Izumo Kamiki: A skilled Tamer-in-training with two fox spirits, Izumo is a descendant of shrine maidens and often presents a formidable, if sometimes prickly, exterior.

The True Cross Order: Who's Who and Their Roles

Beyond the young students, Blue Exorcist features a robust cast of adult figures within the global exorcist organization, the True Cross Order. These characters, all past their teenage years, guide, protect, and sometimes challenge Rin and his friends.

  • Shiro Fujimoto: Rin and Yukio's charismatic and powerful adoptive father, a former Paladin (the highest rank in the Order). His death is a catalyst for Rin's journey.
  • Mephisto Pheles: The eccentric head of True Cross Academy and, secretly, the demon king Samael, the "King of Time." He plays a morally ambiguous yet crucial role in protecting Rin. His age is truly ancient, being one of the Eight Demon Kings.
