KADOKAWA Co., Ltd. Press release: October 24, 2025 To Members of the Press Five new series coming in October! Included are sequels to a romantic comedy that’s on the rise, and a sequel to a hugely popular series whose fourth anime season has everyone eagerly awaiting it! The new MF Bunko J October releases will be released on Friday, October 24th!! The release date for the new MF Bunko J releases for October 2025 has arrived! This month, we’re introducing five new titles: “The Frontline of Dungeon Reporting”, “The Broken Sword’s Theory of Happiness: The Red-Haired Alchemist and the Timid Former Sword Saint”, “A Stray Cat Befriended Me, and Before I Knew It, I Was His Owner.”, “Row God Wants to Be Tied Up”, and “Proposal”! Our first title is “The Frontline of Dungeon Reporting”! Neruko, a young girl who dreams of becoming an accompanying reporter, knocks on the door of the newspaper company, Bell Times. He dreamed of writing spectacular articles about adventurers’ exploits, but before he knew it, he was tired of writing nothing but vulgar gossip articles. While staking out a story about the hero Bissia’s love life, he learned that the “Witch of Calamity,” Iris, was scheduled for execution in a month. He couldn’t let this opportunity slip away, so he attempted to break into the prison where Iris was being held, and finally managed to meet her face-to-face! However, upon seeing Iris, Nerko instinctively became convinced. She was the person he had been searching for for 10 years. She was the one who saved him from the clutches of evil during the Calamity 10 years ago. To prevent the truth from being covered up, a rookie journalist’s thrilling investigation into a hellish dungeon begins now! Our second work is “The Broken Sword’s Theory of Happiness: The Red-Haired Alchemist and the Timid Former Sword Saint”! In 1863, in Kyoto, where the “correct history” had been altered, a genius British alchemist named Morgana revived a swordsman. That swordsman was Kondo Sansuke, the second head of the Tennen Rishin-ryu school of swordsmanship, a master swordsman. However, after being stabbed by an assassin before he could even draw his sword in the brink of death, he lost confidence and abandoned the sword. In order to prevent the downfall of the Shinsengumi, whose leader would later become the fourth head of the Rishin-ryu school, Morgana needed to somehow enlist Sansuke’s help. To that end, Morgana convinced Sansuke to enjoy a new life without a sword, and successfully lured him out of the tomb. Then, in the midst of a carnage where elite Shinsengumi members were about to assassinate the current leader, Serizawa Kamo, Morgana abandoned Sansuke, who had abandoned his sword. A heart-warming novel weaving swordplay and alchemy that will burn every last drop of your soul begins! Our third work is “A Stray Cat Befriended Me, and Before I Knew It, I Was His Owner.” Onsengawa Riku is a typical second-year high school student who, to put it nicely, is cool and serious, but to put it bluntly, is a dreary, introverted person. Riku, who has a volatile personality, changed his route to school today as he went on his daily walk, but on the way, he spotted a high school girl in an unfamiliar uniform in a park. She seemed to be looking after a stray cat. Her name was Hayami Tamau. He was curious about her, but with the cloudy weather today, there was a high chance that the stray cat would get wet in the rain. After talking to a trusted senior and getting the cat rescued, Riku returned to the park and spotted Tamau, soaked in the rain. She looked like a lonely, stray cat. Riku spoke to Tamau without frightening her, and she responded like a cat, gradually opening up. “I never thought I’d find two cats in one day.” That was the thought that led to their first meeting. Check out the slightly strange daily life of a girl who’s like a stray cat and her wayward owner! Introducing our fourth work, “Nawagami-san Wants to Be Tied Up”! Seishirō Kaino, a high school student at the prestigious private Kiririn Academy, has been appointed the personal butler of his classmate, Seiren Nawagami, who comes from one of Japan’s most prestigious families. Nawagami-san is beautiful and a ladylike girl, but there are also rumors of her violent past, such as her causing trouble in class and beating up boys from other schools. She’s a delinquent student who doesn’t hang out with anyone, is foul-mouthed, aloof, and sadistic. Just when you wonder what’s going to happen, one day, as her personal butler, you enter her room and… “Ah… Hehe… (heart) (heart) Phew, phew… I, I’m sorry, bye////” you say, witnessing her in a ridiculous state (self-censorship). And what’s more, you end up fulfilling her “requests” every day!? Nawagami-san is a masochist who only shows her true colors to me. Her possessiveness and requests for me continue to escalate──!? Finally, we’ll introduce “Proposal”! Eir, an angel whose goal is to bring happiness to people, has integrated into human society as a singer known as “eL.” One day, he meets Sara, a fragile girl who is a fan of eL and is on the path to misfortune. She has good dreams, but she is wearing a cursed item known as a “charm” that corrodes her soul. The only way to save Sara is to remove it, but she is unable to remove the charm’s powers. So Eir reveals himself to be an angel and decides to grant Sara’s wish. Then Sara “Will you marry me?” He suddenly proposed marriage. To help Sara, who is emotionally unstable and in danger of breaking down without support, Eir accepts a false marriage. The wildly popular song “Proposal” has been turned into a shocking novel! In addition, there are plenty of noteworthy works, including a new release of a romantic comedy featuring an alluring, aggressive character, as well as new releases from MF Bunko J’s most popular series! The new October issue of MF Bunko J will be released on Friday, October 24th! ♦Click here for the official website, “MF Bunko J October Issue Information”:
