ufotable, the studio behind Demon Slayer’s animation

The name appears in the credits of every episode, just before the title: ufotable. For many fans, it is the studio that turned an already popular manga into a worldwide phenomenon. The waves of Water Breathing, Rengoku’s flames, the night Tanjiro and Nezuko faced Rui: everything you remember on screen comes through its workshops.

Here is who is behind this name, what the studio did before Demon Slayer, how it works, and why its animation looks like no other. To place each season in the story, our page Demon Slayer in what order, seasons and films goes over everything in order.

Who is ufotable?

ufotable is a Japanese animation studio founded in October 2000 by Hikaru Kondō, a producer who had worked at Telecom Animation Film. The name has an unexpected origin: while thinking about his future studio, Kondō came across a table shaped like a flying saucer. He bought it, and the studio would be called ufotable, the UFO table, written in lower case.

The headquarters are in Tokyo. In 2009, the studio opened a second base in Tokushima, on the island of Shikoku, its founders’ home region. Part of Demon Slayer’s animation is drawn there, far from the bustle of the capital.

The studio works hand in hand with Aniplex, which produces the series, and Shūeisha, the manga’s publisher. But it is at ufotable that everything takes shape: the direction, the drawing, the effects, the lighting and the 3D.

Before Demon Slayer, Fate and Kara no Kyōkai

Before meeting Tanjiro, ufotable made a name for itself among animation enthusiasts with dark, spectacular works. From 2007, it adapted Kara no Kyōkai, a series of novels by Kinoko Nasu, for the cinema. Then came Fate/Zero in 2011, Fate/stay night: Unlimited Blade Works in 2014, then the Heaven’s Feel film trilogy, from 2017 to 2020.

The studio also animated video game adaptations: God Eater in 2015, then Tales of Zestiria the X in 2016, directed by Haruo Sotozaki, the future director of Demon Slayer. These years built a team used to night fights, glowing weapons and layered light effects.

The table covers the studio’s major works, from its first films to today.

When the Demon Slayer adaptation was announced, those in the know knew what to expect. The rest of the public discovered it in April 2019, episode after episode.

A studio that keeps everything under one roof

In Japanese animation, it is common to hand part of the work to outside companies: in-between drawings, colours, backgrounds, sometimes entire episodes. ufotable does the opposite. The studio brings together under one roof its animators in Tokyo and Tokushima, its 3D team, its background painters and its compositing department.

This choice costs time, but it gives something rare: a quality that does not collapse in the middle of a season. In Demon Slayer, there is no “botched” episode that makes the forums laugh, which often happens when a series has to keep up a weekly pace.

The downside is patience. The seasons are spaced out, and each arc takes months of work. For fans, the wait is part of the ritual: you know the next part will live up to the previous one. Our article on how many seasons Demon Slayer has traces this calendar, from the first episode to the Infinity Castle.

Compositing, the studio’s signature

The word comes up in every analysis of the ufotable style. Compositing is the stage where the drawn characters, the painted backgrounds and the digital effects are assembled into a single image. At ufotable, this stage is entrusted to a team led by Yūichi Terao, and it carries as much weight as the drawing itself.

In concrete terms, each shot is built in layers. The characters remain hand-drawn. On top come the light flowing over a face, the breath coming out of a mouth in the cold, the sparks of a blade, the depth of field that blurs the background as a camera would. The result has the warmth of a drawing and the depth of a film.

That is what gives Demon Slayer’s fights their brilliance. A blade slicing through the night leaves a streak of light, an explosion lights faces from the side, the snow catches the glow of lanterns. You do not necessarily notice it, but your eye feels it.

This principle of layered planes is found on our light frame: several offset, backlit layers of illustration that give depth to Tanjiro and the Hashira. It is filed in the lamps and night lights collection and among the Demon Slayer decorations.

Water Breathing, from woodblock prints to the screen

Tanjiro’s first technique is also the series’ first great visual success. For Water Breathing, Haruo Sotozaki says he drew on old Japanese woodblock prints, and Tanjiro’s waves recall those of Hokusai. Finding the right look took many tests on line thickness, carried out with Yūichi Terao.

According to Yūma Takahashi, the series’ producer at Aniplex, these waves are almost entirely hand-drawn, with just a little 3D at the assembly stage. The contrast between the stylised, almost graphic wave and the rest of the image, more realistic, is what makes it so recognisable.

This choice set the tone for the whole series: each breathing style would have its own image, drawn from Japanese art or from its element. Our page on all the Demon Slayer breathing styles reviews them, and our portrait of Giyu Tomioka, the Water Hashira introduces the master of this style.

Giyu brings his wave all the way to your shelf: on his 17 cm figure, a translucent blue wave curls under his feet and lets the light through. It awaits you in the complete Giyu Tomioka collection and in the collection of all figures.

Episode 19, the night everything changed

On 10 August 2019, Japan discovered episode 19 of Demon Slayer, titled “Hinokami”. On Mount Natagumo, Tanjiro is trapped by Rui’s threads. He remembers the dance his father performed every new year, and his blade catches fire. At the same moment, Nezuko wakes up and sets the threads ablaze with her blood.

The shift from Water Breathing, blue and graphic, to the flames of the Dance of the Fire God, orange and almost alive, happens before the viewer’s eyes, carried by the song Kamado Tanjirō no Uta. The next day, the episode was being talked about far beyond Japan.

Fans settled the matter a few months later: at the Crunchyroll Anime Awards in February 2020, Demon Slayer was voted anime of the year, and Tanjiro and Nezuko’s fight against Rui won the award for best fight scene. Our article on the Dance of the Fire God explains the technique, and the one on Rui and the spider family tells of the demon Tanjiro faces that night.

Backgrounds, 3D and spinning houses

Behind the characters, Demon Slayer’s backgrounds are painted with a care visible in every shot: bamboo forests under snow, wisteria in bloom, alleys lit by lanterns. They set the story in Taishō-era Japan, at the start of the twentieth century, between mountain villages and the first electric lamps.

3D comes in where drawing alone would struggle. In Kyogai’s house, every beat of the drum makes the rooms spin, and the camera turns with them, characters included. On the Mugen Train, the carriages race through the night without their perspective shifting a single line. And the Infinity Castle, with its floors that move to the sound of Nakime’s biwa, relies heavily on three-dimensional sets.

The principle remains the same: 3D serves as a skeleton, then drawing and compositing cover it so it does not show. Our article on Kyogai, the drum demon tells the story of this failed writer turned demon, and the one on Infinity Castle, part 1 shows what the studio made of the castle.

One effect per breathing style, from mist to flames

After water and fire, each new character has brought their own effect. Zenitsu’s thunder cracks in yellow bolts that slice up the screen. Rengoku’s flames rise in golden columns. Mitsuri’s Love Breathing ripples like a ribbon, and Tengen’s Sound Breathing explodes in fireworks.

Muichiro’s mist is perhaps the most delicate. In the Swordsmith Village, it wraps the boy in turquoise veils that blur the opponent’s view, and his seventh form, which he invented himself, makes the mist dance like a cloud. The same season also shows the mark that appears on his face when he recovers his memory.

Our portrait of Muichiro Tokito, the Mist Hashira tells of this awakening. And to keep this mist on your wall, our Muichiro poster is filed in the posters collection and the complete Muichiro Tokito collection.

The team behind the series

A few names come back each season. Haruo Sotozaki has directed the series since the first episode, and the films along with it. Akira Matsushima does the character designs: he is the one who translated Koyoharu Gotouge’s line work into drawings able to move without losing their character. Yūichi Terao leads the compositing, and Yuki Kajiura and Go Shiina compose the music.

This stability matters as much as the technique. From one arc to the next, Tanjiro keeps the same face, the fights keep the same grammar, and the viewer never feels they are watching a different series. Our article on the Demon Slayer theme songs presents the voices and music that accompany these images.

Faithfulness to the manga is also part of the work. The studio adds scenes, lengthens fights, develops memories the manga only touches on. Our article on the differences between the anime and the manga lists them one by one.

Tokushima, Machi Asobi and the studio’s cafés

ufotable does not just produce. Since October 2009, the studio has organised an animation festival in Tokushima, Machi Asobi, with the city’s tourist office. It takes place twice a year, in spring and autumn, and Demon Slayer has already had its place there.

The studio also runs cafés bearing its name, the ufotable Cafés, where its series regularly get their own menus and decorations. For a fan travelling in Japan, it is a chance to see the studio’s world up close, away from the screen.

This link with Tokushima is no detail. A medium-sized city on Shikoku has become, thanks to a studio, one of the places where Japanese animation is celebrated every year.
