Welcome to Demon School! Iruma-kun Season 4 has released a new main trailer and promotional visual, offering a closer look at the major events still waiting for Iruma Suzuki and his classmates during the second half of the season.
The latest preview places a strong focus on the upcoming Dem-dol Games, an extravagant competition built around the demon world’s popular idols. The new visual gathers Team Devimus and their main rival Gyari while introducing three additional voice actors who will appear in the ongoing fourth season.
New Trailer Previews the Second Half of Season 4
The newly released trailer previews several important events that will unfold as Welcome to Demon School! Iruma-kun Season 4 continues. While the first episodes have already advanced Iruma’s story at Babyls Demon School, the remaining portion of the season will take him into larger social gatherings, political events and competitions connected to the future of the Netherworld.
The footage includes scenes related to the Deviculum, the Descent Ceremony, the Thirteen Crowns Dinner and the Dem-dol Games. These events expand the story beyond ordinary school activities and bring Iruma into contact with influential demons whose decisions could shape the future leadership of the demon world.
The trailer also highlights several members of the Misfit Class, showing that the season will continue balancing Iruma’s personal development with the growth of his classmates. As the students take part in increasingly demanding challenges, their individual talents and relationships become more important.
The Dem-dol Games Take Center Stage
The new visual is centered on the Dem-dol Games, one of the most colorful and energetic events featured in the fourth season. Demon idols, commonly known as dem-dols, are major celebrities in the Netherworld, and their performances combine music, charisma, magical talent and intense competition.
Iruma previously entered the dem-dol world through his female idol identity, Irumi. Although the transformation began as an unusual attempt to help Kerori Crocell, Irumi became unexpectedly popular and proved that Iruma could command a stage despite his naturally modest personality.
Season 4 brings Irumi back for a much larger competition. This time, Iruma will not be performing alone. Team Devimus includes several familiar characters using their own dem-dol personas, creating a group filled with very different personalities and performance styles.
Team Devimus Appears in the New Visual
The new promotional artwork features Team Devimus at the center. The group includes Irumi, Kuromu, Lindy and Merry, the idol forms of Iruma Suzuki, Kerori Crocell, Shax Lied and Ameri Azazel.
- Irumi: Iruma Suzuki’s dem-dol identity
- Kuromu: Kerori Crocell’s famous idol persona
- Lindy: Shax Lied’s dem-dol form
- Merry: Ameri Azazel’s idol persona
The group’s unusual composition gives the competition a strong comedic element. Iruma is already familiar with performing as Irumi, but other members of the team must adapt to costumes, choreography, audience expectations and the pressure of competing against experienced dem-dols.
At the same time, the competition is not treated only as a joke. Dem-dols hold enormous cultural influence in the Netherworld, and the Games require their participants to demonstrate confidence, creativity, endurance and the ability to capture an audience’s attention.
Gyari Becomes Team Devimus’ Main Rival
The new visual places Gyari opposite Team Devimus, establishing her as the group’s major rival during the Dem-dol Games. She is a charismatic and highly competitive performer whose presence raises the pressure surrounding the event.
Gyari is voiced by Misato Matsuoka. Her character brings a much more aggressive energy to the dem-dol competition, contrasting with the friendship and improvisation that define Iruma’s team.
The rivalry is also connected to Kuromu, whose professional experience as a popular dem-dol makes the Games deeply personal. While Iruma and the others may initially approach the event as another challenge, Kuromu understands the pride, pressure and ambition that exist behind the glamorous performances.
Gyari’s arrival therefore gives the storyline both comedy and emotional tension. The competition becomes a test of whether Team Devimus can work together while facing an opponent whose confidence and stage presence could overwhelm them.
Three New Voice Actors Join the Cast
The latest update confirms three additional cast members for the fourth season. Along with Misato Matsuoka as Gyari, the anime introduces Leviathan Leiji and Belial-Berry Razberry, two characters connected to the most powerful demon families in the Netherworld.
- Yuma Uchida as Leviathan Leiji
- Yoshitsugu Matsuoka as Belial-Berry Razberry
- Misato Matsuoka as Gyari
Leiji and Razberry belong to the same generation of powerful heirs as Iruma. They are the grandchildren of members of the Three Greats, the legendary demons whose influence extends across the Netherworld.
Their introduction is important because Iruma is Sullivan’s grandson, even though he is secretly human and not related to Sullivan by blood. As the demon world begins considering its future leadership, Iruma increasingly finds himself compared with heirs who were raised inside powerful demon families.
Leviathan Leiji and Belial-Berry Razberry Enter the Story
Leviathan Leiji and Belial-Berry Razberry represent two different responses to the expectations placed upon the grandchildren of the Three Greats. Both possess powerful family connections and could become important figures in the future political structure of the Netherworld.
Their appearance also forces Iruma to consider how other demons view him. To most of the Netherworld, he is Sullivan’s unusual but promising grandson, a student who has repeatedly achieved things that should have been impossible for someone of his rank.
Iruma never intended to become a candidate for leadership or attract the attention of the most powerful demons. However, his kindness, determination and ability to inspire others continue placing him in situations where he can no longer remain unnoticed.
Meeting Leiji and Razberry gives the anime an opportunity to explore Iruma’s position among a new generation of potential leaders. They may become rivals, allies or both as the story develops.
Major Netherworld Events Are Still Ahead
The fourth season still has several major events to cover beyond the Dem-dol Games. The new trailer teases the Deviculum, also known as the Grand Noble Gathering, where influential demons meet in an elaborate social setting.
The season will also explore the Descent Ceremony and the Thirteen Crowns Dinner. These events connect Iruma’s school life with the political structure of the wider Netherworld.
The Thirteen Crowns are among the most powerful demons in existence, and questions surrounding the vacant position of Demon King continue influencing the direction of demon society. Sullivan is closely connected to these discussions, which makes Iruma’s growing reputation increasingly significant.
Although Iruma remains focused on protecting his secret and supporting his friends, the adults around him are beginning to recognize that his influence could eventually extend far beyond Babyls.
Season 4 Is Airing for Two Consecutive Cours
Welcome to Demon School! Iruma-kun Season 4 began airing in Japan on April 4, 2026. The season is scheduled to run for 24 episodes, giving the anime enough time to adapt several important story arcs without rushing their character development.
Crunchyroll is streaming the season internationally, allowing viewers to follow Iruma and the Misfit Class as the episodes are released.
- Season premiere: April 4, 2026
- Total episodes: 24
- International streaming: Crunchyroll
- Animation production: BN Pictures
The two-cour format is especially valuable for a series with such a large cast. Iruma’s story depends heavily on his relationships with classmates, teachers, family members and political figures, meaning that important developments need time to unfold naturally.
What Is Welcome to Demon School! Iruma-kun About?
Welcome to Demon School! Iruma-kun follows Iruma Suzuki, a kindhearted human teenager whose irresponsible parents sell him to a demon named Sullivan.
Iruma expects to be eaten or punished, but Sullivan has a completely different plan. The powerful demon desperately wants a grandson and adopts Iruma into his luxurious home, treating him with overwhelming affection.
Sullivan then enrolls Iruma at Babyls Demon School, where he serves as chairman. Iruma must attend classes alongside demons while hiding the fact that he is human, since humans are believed to be rare and potentially delicious creatures in the Netherworld.
Iruma has spent his entire life avoiding conflict and accepting every request made of him. Ironically, those survival skills repeatedly make him stand out. His reflexes allow him to avoid attacks, his kindness turns enemies into friends and his determination helps him overcome challenges far beyond what anyone expects.
Iruma Continues Growing Into a Leader
One of the most important developments across the anime is Iruma’s gradual transformation from a frightened boy into someone capable of expressing his own ambitions.
At the beginning of the story, Iruma wants nothing more than to remain unnoticed. Years of mistreatment by his parents taught him to prioritize survival and satisfy everyone around him, even when doing so caused him harm.
His new life in the Netherworld changes that pattern. Sullivan, Opera, Alice, Clara and the rest of the Misfit Class give Iruma a support system he never experienced in the human world.
As Iruma becomes more confident, he begins identifying things he genuinely wants. His ambitions are still shaped by kindness, but they are no longer based only on avoiding danger or pleasing others.
Season 4 continues that development by placing him in situations involving performance, politics and leadership. Whether he is standing on a dem-dol stage or meeting powerful demon heirs, Iruma must decide what kind of person he wants to become.
The Misfit Class Remains Central to the Story
Iruma’s classmates remain one of the greatest strengths of the series. The Misfit Class began as a collection of unusual and difficult students, but they have gradually become a close group capable of supporting one another through increasingly demanding challenges.
Alice Asmodeus is fiercely loyal to Iruma and treats nearly everything he does as an act of genius. Clara Valac brings unpredictable energy to the group while also developing a deeper emotional understanding of her friendship with Iruma.
Characters such as Shax Lied, Kerori Crocell, Sabnock Sabro, Ameri Azazel and Purson Soi have also received opportunities to grow beyond their initial comedic roles.
The Dem-dol Games make use of several of these established relationships. Lied, Kerori and Ameri join Iruma in a competition that requires trust, performance and the willingness to reveal sides of themselves they normally keep hidden.
Main Voice Cast
The familiar voice cast returns for the fourth season, led by Ayumu Murase as Iruma Suzuki. Their performances continue to balance comedy, fantasy adventure and the increasingly emotional relationships between the characters.
- Ayumu Murase as Iruma Suzuki
- Ryohei Kimura as Alice Asmodeus
- Ayaka Asai as Clara Valac
- Saori Hayami as Ameri Azazel
- Nao Toyama as Kerori Crocell
- Shoki Yamaya as Shax Lied
- Daisuke Ono as Naberius Kalego
- Takaya Kuroda as Sullivan
- Mitsuki Saiga as Opera
- Setsuo Ito as Purson Soi
- Takehito Koyasu as Amduscias Poro
The new additions expand the season’s already extensive cast and bring several important characters into the anime for the first time.
Production Staff at BN Pictures
Makoto Moriwaki, who directed the previous seasons, now serves as chief director. Ayaka Tsujihashi is directing Season 4, while Kazuyuki Fudeyasu returns to handle series composition.
Yumiko Hara is responsible for the character designs, and BN Pictures continues handling animation production.
- Chief director: Makoto Moriwaki
- Director: Ayaka Tsujihashi
- Series composition: Kazuyuki Fudeyasu
- Character design: Yumiko Hara
- Music: Akimitsu Honma and Yayoi Sekimukai
- Animation production: BN Pictures
The transition allows the anime to introduce new direction while maintaining continuity with the previous seasons. Moriwaki’s continued involvement helps preserve the energetic comedy and emotional warmth that have defined the adaptation since its debut.
Based on Osamu Nishi’s Manga
Welcome to Demon School! Iruma-kun is written and illustrated by Osamu Nishi. The manga began serialization in Akita Shoten’s Weekly Shonen Champion magazine in 2017.
The series has grown into a major fantasy comedy franchise thanks to its large cast, colorful world and steady character development. Although the premise begins with a human hiding among demons, the story gradually expands into a broader exploration of friendship, ambition and the future of the Netherworld.
The manga has also inspired multiple spin-offs, including Welcome to Demon School! Iruma-kun: IruMafia Edition, which reimagines the characters in a mafia setting and is scheduled to receive its own anime adaptation in 2027.
Why the Dem-dol Games Matter
The Dem-dol Games may appear to be a lighthearted idol storyline, but the event reflects several of the anime’s central themes. Iruma is once again placed in a role he never expected, yet his willingness to support his friends allows him to succeed.
The competition also gives characters such as Kerori an opportunity to confront professional ambitions and personal rivalries. Her life as Kuromu is not simply a hobby. Being a dem-dol is an important part of her identity and a field in which she has worked hard to earn recognition.
For Ameri and Lied, joining the team requires stepping outside their normal roles. Ameri is usually seen as a strong and respected student council president, while Lied is known for games, tricks and social confidence. Becoming Merry and Lindy allows them to explore completely different sides of themselves.
Iruma’s return as Irumi also shows how much he has changed. The frightened student who once wanted to disappear can now stand in front of a massive audience and use his presence to inspire others.
Final Thoughts
Welcome to Demon School! Iruma-kun Season 4 is preparing for an eventful second half with a new main trailer and promotional visual focused on the Dem-dol Games.
The update introduces Yuma Uchida as Leviathan Leiji, Yoshitsugu Matsuoka as Belial-Berry Razberry and Misato Matsuoka as Gyari. It also teases several major events still to come, including the Deviculum, the Descent Ceremony and the Thirteen Crowns Dinner.
With 24 episodes planned and Crunchyroll streaming the season internationally, Iruma’s fourth anime chapter still has many important developments ahead. From political gatherings to an extravagant demon idol competition, the remaining episodes promise to push Iruma further into the spotlight he once spent his entire life trying to avoid.
