The highly anticipated television anime adaptation of By’s horror-comedy manga, Let’s Go Kaikigumi, has officially unveiled its full trailer, a striking new key visual, and the full lineup of its opening and ending theme songs. The revelations, made on Saturday, also introduced a new voice actor joining the production, generating significant buzz within the anime community just weeks before its scheduled premiere.
The newly released trailer offers fans a comprehensive glimpse into the chaotic and supernatural world of Let’s Go Kaikigumi. It prominently features the energetic opening theme, "Kimi ga Waruindakara ne" ("’Cuz It’s Creepy, Right?"), performed by the popular idol group SWEET STEADY. Complementing this is the enigmatic ending theme, "Iwashite ne?" ("May You Curse Me?"), by the artist Uketsu, whose unique contributions are already hinting at the anime’s distinctive tone. The trailer showcases dynamic animation sequences that capture the essence of the manga’s blend of humor and unsettling paranormal events, further whetting the appetite of eager viewers.
Expanding the Cast and Creative Team
Adding to the excitement, the anime’s staff confirmed that acclaimed voice actress Kana Hanazawa will lend her talents to the character of Yukinko. Hanazawa, known for her extensive and diverse roles in popular anime such as Ichika Orimura in Infinite Stratos and Kanade Tachibana in Angel Beats!, brings a wealth of experience and a dedicated fanbase to the project. Her inclusion is expected to further elevate the anime’s appeal.
The production is being helmed by director Yutaka Hirata, who previously served as a unit director for the STARMYU series. Hirata’s experience in bringing musical and character-driven anime to life suggests a nuanced approach to Let’s Go Kaikigumi‘s unique narrative. The series scripts are being supervised and written by Mutsumi Ito, whose credits include the well-received ROOM CAMP. This pairing of directorial and writing talent promises a cohesive and engaging storytelling experience.
Character design is in the capable hands of Yoshimitsu Yamashita, an artist with a distinguished portfolio that includes character designs for Mushibugyō and the critically acclaimed Blade of the Immortal. Yamashita’s ability to translate distinct manga art styles into animated form is a significant asset to the adaptation. Furthermore, Uketsu, an individual renowned for their work on the Omocoro web service and the novel The Strange House (which also received a manga adaptation), is deeply involved in the anime’s production. Uketsu’s role extends to "song collaboration," indicating a significant creative influence on the music and thematic elements of the series.
A Deep Dive into the Premise
Let’s Go Kaikigumi is rooted in a compelling horror-comedy premise. The narrative centers on a protagonist who, despite his inherently cowardly nature, finds himself thrust into the world of the supernatural. The story kicks off when he encounters Mechako, the formidable leader of the "Kaikigumi," an organization tasked with managing ghosts and supernatural entities that aim to frighten humans. Through a series of unforeseen circumstances, the protagonist becomes involved in the Kaikigumi’s operations, leading to a cascade of bizarre, yet curiously non-terrifying, phenomena surrounding him. This unique blend of the mundane and the paranormal, seasoned with dark humor, has been a hallmark of By’s original manga.
Chronology of Development and Release
The Let’s Go Kaikigumi manga first captured the attention of readers when it began serialization on the Omocoro web service in 2018. For six years, fans followed the unfolding adventures and peculiar encounters of the protagonist. The series concluded its run in 2024, paving the way for its highly anticipated anime adaptation.
The announcement of the anime adaptation itself was made in October 2025, signaling a swift transition from manga conclusion to animated production. This rapid development underscores the manga’s popularity and the perceived potential for a successful anime series. The subsequent unveiling of key visuals, character designs, and now the full trailer and theme songs, indicates a well-orchestrated promotional campaign leading up to the broadcast.
The anime is slated to premiere on July 5, 2026. It will be broadcast on TBS and its 27 affiliated channels every Sunday at 4:30 p.m., which translates to 3:30 a.m. EDT. This late-night or early-morning slot is common for anime series in Japan, often catering to a dedicated fan base that is accustomed to such scheduling. The international availability and streaming platforms for the series are expected to be announced in the coming weeks, which will be crucial for its global reach.
Supporting Data and Industry Context
The horror-comedy genre within anime has seen a resurgence in recent years, with titles like Chainsaw Man and Jujutsu Kaisen achieving massive international success by blending visceral horror elements with sharp, often dark, humor. Let’s Go Kaikigumi appears poised to carve out its own niche within this popular category. The manga’s serialization on Omocoro, a platform known for its unique and often unconventional content, suggests a built-in audience familiar with offbeat storytelling.
The anime industry’s continued investment in adapting popular manga series reflects a proven model for success. By translating beloved source material into a new visual medium, studios can leverage existing fan bases while attracting new audiences.
