The clip features the anime's opening theme song "Issen" (Flash") for the first time, performed by Japanese virtual duo VESPERBELL , which consists of YOMI and KASUKA . This is the first time that they have performed a theme song for an anime series. My Status as an Assassin Obviously Exceeds the Hero's Anime Main Trailer 1 VESPERBELL was formed in June 2020 and made their major debut on July 24, 2024 from Warner Music Japan. YOMI has a highly expressive and powerful voice, while KASUKA has a pop voice. The duo are active with both cover songs based on J-POP, rock and anime songs, as well as their original songs with more than 270,000 subscribers on their YouTube channel. Message from YOMI: Thank you very much for allowing us to sing the opening theme song for "My Status as an Assassin Obviously Exceeds the Hero’s," a work that I like very much, both in terms of its title and its world view! This is the first time for us to sing a theme song for an anime, and I was already nervous from the time of recording, but now I am looking forward to delivering the song to you all through the anime. May you love the work and the music a lot! Thank you very much! ^^ ^^ Message from KASUKA: I am very honored that VESPERBELL is in charge of the opening theme song for “My Status as an Assassin Obviously Exceeds the Hero’s ." We did our best to express the tension and speed of the work, as well as the strength and conflict of the characters in the music. We hope you enjoy the music as much as the original novel and the anime! VESPERBELL artist visual In addition to the previously announced cast of Takeo Otsuka as the protagonist Akira Oda and Saku Mizuno as the main heroine Amelia Rosequartz, three new voice cast members were also revealed. Sanae Kobayashi (Allen Walker in D.Gray-man ) voices Yoru, a demon of the “Black Cat” race. Usually, she takes the form of a black cat. Message from Sanae Kobayashi: I am captivated by Akira's appearance and Amelia's loveliness. I am very much looking forward to seeing the expressions and actions of the characters in the anime and how the story will unfold in the beautiful scenery of another world where the imagination is limitless! I am in charge of the voice of Yoru, and I am always excited to see how I can link the cat's appearance with my role, which is both difficult and interesting. Please watch the show! Yoru character visual Sanae Kobayashi Konomi Tamura (Isaki Magari in Insomniacs after school ) voices Lia Lagoon, a mysterious girl who knows the secret behind Akira and others' summoning to another world. Whether she is an enemy or an ally remains to be seen. Message from Konomi Tamura: I am Konomi Tamura and I will be playing the role of Lia in "My Status as an Assassin Obviously Exceeds the Hero’s." When I was reading the details of Lia's character during the audition, I saw the sentence, "When she starts running, she never stops, and if someone is in trouble, she immediately goes to help them," I thought that she is a girl who is not two-faced and has a straightforward sense of justice that makes her blind to her surroundings. I would like you to pay attention to Lia as she grows little by little through her involvement with Akira and others. Lia Lagoon character visual Konomi Tamura Junichi Suwabe (Keigo Atobe in The Prince of Tennis ) voices Saran Mithray, the commander of the Knights of the Retice Kingdom. He is the only one whom Akira, who often acts alone, trusts. He provides combat guidance to Akira's classmates who have been summoned to another world. Message from Junichi Suwabe: I am in charge of the role of Saran Mithray. He is the Knight Commander, strikingly handsome, and also strong. What role does he play in this story? I hope you will watch the anime. Thank you for your support. Saran Mithray character visual Junichi Suwabe RELATED: My Status as an Assassin Obviously Exceeds the Hero's TV Anime Announced for October 2025 Nobuyoshi Habara , best known for his directorial works for the Fafner series, will serve as the director. Other staff members include series composition writer Kunihiko Okada ( Yowamushi Pedal ), character designer Hirona Okada ( Gundam Build Metaverse ) and Kaoru Saito ( Mobile Suit Gundam the Witch from Mercury ), soundtrack composer Satoshi Igarashi ( TOKYO LOGIC ), monster designer Rihiro Yamane ( The Brave Express Might Gaine ), and main animator Mitsuru Ishihara ( Mega Man Battle Network ). Sunrise is in charge of animation production. The series began serialization on Shousetsuka ni Narou in January 2017. Japanese publisher Overlap began releasing the novel's print edition featuring illustrations by Tozai in its Overlap Bunko imprint starting November 2017, with four volumes available in Japan to date. The novel's manga adaptation, illustrated by Hiroyuki Aigamo, began on the publisher's Comic Gardo website in July 2018, with six volumes released to date. The total circulation of the entire series (including both print and digital) exceeds 1.5 million copies. Seven Seas Entertainment, which licenses both the novel and manga , describes the series: Oda Akira is the kind of guy who people forget is even there. His unassuming nature pays off, though, when his entire class is swept away to a fantasy world, and he slips easily into his new role as a silent assassin. Between his suspiciously high starting stats and too many details that don’t fit, Akira is sure something is wrong. But digging into royal secrets is a dangerous game, and when Akira uncovers an evil scheme, he also makes a powerful enemy—the very king who brought him to this world! With the help of the elven spirit medium Amelia, can he find the power to set things right, and get his revenge?
