A new trailer for Kaiju No. 8 Season 2 has been released, offering a first look at the upcoming “Bungui Tōge Tōbatsu Sakusen-hen” (Bungui Pass Subjugation Operation arc). The latest arc is set to commence with Episode 19, which marks the eighth episode of the second season, airing this Saturday.
The popular anime adaptation, which premiered its first season in 2024, is now delving deeper into the Defense Force’s ongoing battle against colossal Kaiju threats, with Season 2 promising heightened stakes and new challenges.
Unveiling the “Bungui Pass Subjugation Operation” Arc
The newly released trailer showcases glimpses of the “Bungui Pass Subjugation Operation” arc, hinting at the intense conflicts that await Kafka Hibino and the rest of the Defense Force. While specific details of the operation remain under wraps in the trailer, fans anticipate a focus on strategic combat and the continued evolution of the series’ narrative.
Season 2 is expected to explore the “Kaiju Weapon Arc” and “Compatible User Arc,” which in the manga cover chapters 40-55 and 56-68, respectively. The “Compatible User Arc” reportedly begins with episode 6 of Season 2 and involves characters testing their compatibility with weapons derived from Kaiju remains. This arc will also touch upon internal conflicts within the Defence Force, adding layers of complexity to the storyline.
Continuing the Fight Against Kaiju No. 9 and New Threats
Following the dramatic conclusion of Season 1, where Kafka Hibino’s identity as Kaiju No. 8 was revealed, the series is now set to confront the increasingly intelligent and dangerous Kaiju No. 9. The villain, who gained new intelligence and began planning a major attack on the Defense Force, will be a central antagonist in the upcoming season.
The trailer suggests that Kaiju No. 9 will not be the sole adversary. Viewers can expect to see the introduction of other powerful foes, including an army of giant fire ants and a mysterious, “abstract” Kaiju, further escalating the threats faced by the Defense Force. These new challenges will likely push Kafka and his comrades to their limits, forcing civilians to flee attacks and the Defense Force to manage extensive debris.
Production and Streaming Details
The Kaiju No. 8 anime is produced by animation studio Production I.G., with Shigeyuki Miya and Tomomi Kamiya directing. Ichiro Okouchi handles the series composition, Tetsuya Nishio is responsible for character designs and serves as chief animation director, and Mahiro Maeda contributes to the intricate Kaiju designs.

Fans eager to catch up on Kafka’s journey can revisit the first season, which chronicled his transformation from a cleanup worker to a member of the Defense Force after a mini Kaiju took him as a host. His struggle to hide his Kaiju identity while fighting alongside his human teammates, including childhood friend Mina Ashiro, formed the core of the initial arc, culminating in his cover being blown during a critical mission.
