TOKYO – August 23, 2026 – The intense narrative of Yuki Kodama’s action-packed manga, Agent Jupiter, has officially reached its conclusion. The final chapter of the series was published on August 20th, marking the end of a thrilling journey for fans who have followed the exploits of the formidable agent. Released on the digital platform Comic Days, the finale brings a close to Kodama’s latest significant work, which debuted in February 2025.
Agent Jupiter plunges readers into a world of parallel dimensions and intricate revenge plots. The titular protagonist, Agent Jupiter, is depicted as a highly skilled and powerful operative who, after successfully avenging his sister in one parallel world (World B), seeks a quiet retirement in another (World A). His ambition is to shed his formidable identity and embrace a life of normalcy. However, as is often the case with such meticulously laid plans, fate intervenes in the form of a young girl whose sudden appearance irrevocably alters Jupiter’s trajectory and disrupts his carefully constructed peace.
The manga was launched by Kodansha in its Morning two magazine, a platform known for serializing a diverse range of manga titles. The initial release in February 2025 signaled the beginning of what would become a compelling story arc. The series has seen consistent publication, with Kodansha releasing the third compiled volume of Agent Jupiter on June 23rd of this year, providing readers with a tangible collection of the ongoing saga.
A Look Back at Yuki Kodama’s Illustrious Career
The conclusion of Agent Jupiter offers a timely opportunity to reflect on the broader career of Yuki Kodama, an artist who has consistently delivered engaging narratives and memorable characters to the manga community. Kodama’s work is often characterized by its dynamic action sequences, complex character development, and a unique blend of genre elements.
Before Agent Jupiter, Kodama was widely recognized for the beloved vampire comedy, Blood Lad. This series, which began its serialization in Kadokawa’s Young Ace magazine in 2009, garnered a significant international following. Blood Lad concluded its run in September 2016, with its 17th and final compiled volume released in Japan in December of the same year. The popularity of Blood Lad extended beyond the manga pages, inspiring a 10-episode anime adaptation that premiered in 2013. This anime was made available to a global audience through streaming services and home video releases by companies like Viz Media.
Kodama’s prolific output continued with The World of Summoning, known in Japan as Shōkan Suru Sekai. This manga was launched in February 2022 in Kodansha’s Bessatsu Shōnen Magazine. The series, which also saw a simultaneous global release in English and French, concluded its run in May 2023. The third and final compiled volume was published in July 2023, further solidifying Kodama’s reputation for crafting complete and satisfying narratives.
In an earlier venture, Kodama collaborated with Yukinori Kitajima to create the manga Hamatora. This series debuted in Shueisha’s Weekly Young Jump in November 2013 and wrapped up in December 2014. Hamatora was part of a larger multimedia project that included two anime series, stage plays, and a Nintendo 3DS game, showcasing Kodama’s ability to contribute to diverse creative endeavors. Both anime series were streamed by Crunchyroll and later released on home video by Sentai Filmworks.
More recently, Kodama explored a different thematic landscape with Demon Tune. This series was initially launched in Jump SQ. in January 2018 before moving to the digital platform Shonen Jump+ in December 2018. Demon Tune concluded its run in May 2019.
Each of these previous works has contributed to Kodama’s distinctive artistic voice and has built a loyal fanbase eagerly anticipating their next project. The conclusion of Agent Jupiter represents another significant milestone in an already impressive career.

The Narrative Arc of Agent Jupiter
Agent Jupiter presented a compelling premise from its inception. The story centers on an operative who has achieved his ultimate goal – revenge for his sister. This pivotal achievement leads him to seek a tranquil existence, a stark contrast to the life of espionage and conflict he has known. His chosen sanctuary is Parallel World A, a seemingly peaceful dimension where he hopes to blend in as an ordinary citizen.
However, the introduction of a young girl into his life shatters this carefully crafted facade. This unexpected element serves as the primary catalyst for the unfolding plot, forcing Jupiter to confront his past and re-evaluate his desire for a quiet life. The narrative likely explores themes of redemption, the inescapable nature of one’s past, and the profound impact of human connection. The "parallel world" aspect also opens up possibilities for exploring alternate realities, moral ambiguities, and the consequences of choices made across different timelines.
The visual storytelling employed by Kodama, evident in the provided cover art, suggests a dynamic and action-oriented series. The "first volume cover of Agent Jupiter" hints at the character’s formidable presence and the potential for high-stakes confrontations. The artwork, as is characteristic of Kodama’s style, likely balances gritty realism with elements of fantastical design, appealing to fans of both action and science fiction genres.
