The highly anticipated fourth season of the popular anime series “Welcome to Demon School, Iruma-kun” (Mairimashita! Iruma-kun) has officially released its main promotional trailer, confirming an April 4 premiere date. The new video preview showcases the series’ vibrant demonic world and introduces several new characters set to join the chaotic school life at Babyls Demon School.<\/p>\n
The newly released promotional trailer provides fans with their first substantial look at what to expect from the upcoming season. Clocking in at just over a minute, the trailer maintains the series’ signature blend of supernatural comedy and heartwarming character development that has captivated audiences since its 2019 debut. Production remains under the direction of Makoto Moriwaki at Bandai Namco Pictures, with series composition handled by Kazuyuki Fudeyasu.<\/p>\n
Visually, the trailer demonstrates consistent animation quality with the previous seasons, featuring the colorful and exaggerated character designs that have become synonymous with the franchise. The trailer’s pacing suggests the new season will continue balancing slice-of-life school antics with more serious plot developments concerning the Netherworld’s political landscape and Iruma’s unique position as a human living among demons.<\/p>\n
A significant highlight of the trailer is the debut of the new opening theme song, “Ichi Ni no San” (One Two Three), performed by the Japanese rock band Penthouse. The energetic track complements the fast-paced visuals of the trailer, suggesting a season filled with dynamic action sequences and emotional character moments. Penthouse follows in the footsteps of previous artists who have contributed to the series’ soundtrack, including Da Pump and Amatsuki.<\/p>\n
The musical direction for Season 4 continues under Akimitsu Honma, who has composed the score for the series since its inception. The trailer offers brief samples of new background music that maintains the established tonal balance between whimsical comedy cues and more dramatic orchestral arrangements for pivotal story moments.<\/p>\n
The trailer introduces several new characters who will play significant roles in the upcoming season’s narrative. While specific names and voice actors weren’t detailed in this initial reveal, character designs visible in the trailer suggest adaptations of manga arcs that focus on expanding the world beyond the school’s main cast. These additions are expected to bring fresh dynamics to the established relationships between Iruma Suzuki and his demon classmates.<\/p>\n
Based on Osamu Nishi’s ongoing manga series, which began serialization in Weekly Sh\u014dnen Champion in March 2017, the fourth season will likely adapt storylines from later volumes that explore deeper aspects of demon society. The manga’s rich world-building has provided ample material for the anime adaptation, with the previous three seasons covering approximately the first 14 volumes of the source material.<\/p>\n
The trailer concludes with the definitive announcement that “Welcome to Demon School, Iruma-kun” Season 4 will begin broadcasting on April 4. While specific Japanese television channels and streaming platforms weren’t detailed in this initial announcement, previous seasons have aired on NHK Educational TV in Japan, with international distribution handled by Crunchyroll. Fans outside Japan can expect similar streaming availability, though official international release dates typically follow the Japanese premiere by a short interval.<\/p>\n
The April premiere places the new season in the Spring 2024 anime lineup, positioning it alongside other anticipated series. This scheduling continues the pattern established by previous seasons, which have consistently premiered in either spring or fall anime seasons since the franchise’s television debut.<\/p>\n
“Welcome to Demon School, Iruma-kun” has maintained remarkable consistency in both quality and popularity since its initial adaptation. The series follows Iruma Suzuki, a perpetually unlucky human boy sold to a demon by his irresponsible parents. The demon, Sullivan, adopts Iruma and enrolls him in Babyls Demon School, where he must conceal his human identity while navigating demonic education and forming genuine friendships.<\/p>\n
The anime’s success stems from its clever subversion of isekai tropes, its emphasis on character growth over power escalation, and its wholesome exploration of friendship and self-worth. Unlike many supernatural school series, “Iruma-kun” focuses less on combat and more on interpersonal relationships and school competitions, creating a unique niche within the genre.<\/p>\n
While the trailer doesn’t explicitly confirm returning voice actors, industry standards suggest the main cast will reprise their roles. This includes Ayumu Murase as the ever-anxious yet kind-hearted protagonist Iruma Suzuki, and Ryohei Kimura as the flamboyant and loyal demon Asmodeus Alice. Similarly, Sumire Uesaka will likely return as the tsundere demon Clara Valac, whose chaotic energy provides much of the series’ comedic relief.<\/p>\n
The production team’s continuity has been a strength of the franchise, with character designs consistently handled by Satohiko Sano and art direction by Yukihiro Shibutani. This consistency has resulted in a visually cohesive adaptation that faithfully captures the distinct style of Osamu Nishi’s original manga artwork while enhancing it with fluid animation appropriate for television broadcast.<\/p>\n
For manga readers, the trailer hints at adaptation of specific arcs that focus on school festivals, demon family traditions, and the ongoing development of Iruma’s relationship with his demon grandfather, Sullivan. The series has gradually increased stakes while maintaining its core themes, and Season 4 appears poised to continue this balanced approach. The introduction of new characters suggests expansion into previously unexplored aspects of the Netherworld’s social structure and power dynamics.<\/p>\n
The trailer carefully avoids major spoilers while generating excitement through brief glimpses of new settings, magical abilities, and emotional character moments. This strategic presentation suggests the production committee is confident in both retaining existing fans and attracting new viewers to the long-running series.<\/p>\n
The “Welcome to Demon School, Iruma-kun” franchise has expanded significantly beyond its manga and anime origins. Video games, drama CDs, and extensive merchandise lines have capitalized on the series’ popularity. The announcement of a fourth season typically coincides with new product releases, including figurines, apparel, and collaborative campaigns with other brands. The consistent quality of the adaptation has helped maintain merchandise sales between seasons, a notable achievement in the competitive anime market.<\/p>\n
International popularity has grown steadily through legal streaming availability, with the series developing particular strong followings in Southeast Asia and North America. The wholesome nature of the story, combined with its supernatural elements, has created broad appeal across demographic groups that sometimes diverge in their anime preferences.<\/p>\n
As the April premiere approaches, additional promotional materials including character trailers, cast interviews, and behind-the-scenes features are expected to be released. The main trailer serves as an effective appetizer, reminding viewers why they fell in love with Iruma’s demon school adventures while promising new developments that will expand the world in meaningful ways. The series’ enduring appeal lies in its heartfelt message about finding one’s place in an unfamiliar world, a theme that resonates regardless of whether that world is filled with humans or demons.<\/p>\n","protected":false},"excerpt":{"rendered":"
