by The beloved original anime Kabaneri of the Iron Fortress is celebrating its 10th anniversary with an exciting lineup of commemorative projects. As part of the anniversary celebration, the franchise has unveiled a brand-new illustration by original character designer Haruhiko Mikimoto, announced a premium 1/6-scale Mumei figure, and released a new five-minute short anime featuring the return of the original cast and creative staff.
The anniversary project has delighted longtime fans, marking the first major reunion of the series in years and bringing Ikoma and Mumei back to the screen in an all-new animated story.
New “Mumei Ranman” Illustration Revealed
One of the highlights of the 10th anniversary project is a newly drawn illustration titled “Mumei Ranman” by legendary illustrator and original character designer Haruhiko Mikimoto.
The artwork features Mumei relaxing inside the Kotetsujo (Iron Fortress), presenting a more mature interpretation of the fan-favorite heroine while preserving the distinctive art style that made the original series so memorable.
According to Mikimoto, creating the illustration required numerous rough sketches to perfect Mumei’s pose. He also explained that the artwork subtly reflects the passage of time, symbolizing both Mumei’s personal growth and the ten years fans have waited to see her again.
The illustration serves as the foundation for several anniversary projects, including the newly announced collectible figure.

Although brief, the new animation represents the first completely new animated content for the franchise in years, making it one of the biggest highlights of the anniversary celebration.

About Kabaneri of the Iron Fortress
Kabaneri of the Iron Fortress is an original anime television series that aired in 2016, consisting of 12 episodes.
Set in an alternate industrial era inspired by Japan’s late Edo period, humanity is threatened by terrifying undead creatures known as Kabane. These monsters possess steel-like hearts, making them nearly impossible to kill with conventional weapons.
To survive, people live inside heavily fortified stations connected by armored steam trains, while constantly battling the growing Kabane threat.
The story follows Ikoma, a talented young steam engineer determined to create a weapon capable of defeating the Kabane, and Mumei, a mysterious and powerful girl who shares a unique connection with the monsters.
Together, they fight aboard the armored locomotive Kotetsujo, facing both deadly enemies and the harsh realities of survival.
The Creative Team Behind the Series
The anime was directed by Tetsuro Araki, widely known for directing the early seasons of Attack on Titan.
Animation production was handled by WIT STUDIO, the acclaimed studio behind hit anime such as:
- Attack on Titan (Seasons 1–3)
- SPY × FAMILY
- Ranking of Kings
- Vinland Saga (Season 1)
The series also featured:
- Original Character Design: Haruhiko Mikimoto
- Music: Hiroyuki Sawano
- Screenplay: Ichiro Okouchi
The combination of cinematic action, emotional storytelling, and Sawano’s powerful soundtrack helped establish Kabaneri of the Iron Fortress as one of 2016’s standout anime originals.

Hatanaka also joked about Ikoma’s reactions in the new animation before encouraging fans to support the anniversary project and check out the newly announced Mumei figure.
He added that he was grateful for the opportunity to reunite with both the cast and staff once again.
Sayaka Senbongi Was Surprised by the Reunion
Mumei’s voice actress Sayaka Senbongi admitted she never expected to play the character again.
She thanked director Tetsuro Araki and everyone involved for making the surprise reunion possible.
Senbongi said she was delighted to revisit the lives of Ikoma and Mumei and hoped fans would enjoy seeing the beloved characters return after so many years.
She also encouraged fans to take a look at the commemorative figure inspired by Mikimoto’s artwork.

He concluded by saying he would happily create more Kabaneri animation in the future if the opportunity ever arises.
His comments have sparked excitement among fans, many of whom hope the anniversary project could eventually lead to a new anime installment.
Haruhiko Mikimoto on Drawing Mumei Again
Original character designer Haruhiko Mikimoto explained that it had been quite some time since he last illustrated Mumei.
Because of this, he spent considerable time experimenting with rough sketches before deciding on the final pose for the anniversary artwork.
Mikimoto also noted that Mumei’s slightly more mature appearance symbolizes both the passage of time within the story and the many years fans have waited to see her return.
