The official X account for Kyousuke Kamishiro and illustrator TakayaKi's Mamahaha no Tsurego ga Motokano datta (My Stepmom's Daughter Is My Ex) light novel series has confirmed that the ongoing romantic comedy will conclude with its upcoming 14th volume. The final book is scheduled to hit Japanese bookshelves on December 1.
Kamishiro originally launched the web novel series, widely known by the abbreviation TsureKano, on the Kakuyomu self-publishing platform in August 2017. Kadokawa quickly picked up the property, publishing it under their Sneaker Bunko imprint starting in December 2018 with dynamic illustrations provided by TakayaKi. The series resonated deeply with readers, securing a victory in the 3rd Kakuyomu Web Novel Contest under the romantic comedy category and consistently placing high in the prestigious Kono Light Novel ga Sugoi! rankings.
From Web Novel to Global Success
The franchise's immense popularity paved the way for multiple adaptations. Rei Kusakabe launched a manga adaptation on Niconico Seiga's Dra-Dra Sharp# portal in May 2019, while international fans received English licenses through J-Novel Club for the light novels and Udon Entertainment for the manga. Additionally, animation studio Project No.9 adapted the narrative into a 12-episode television anime series that aired during the Summer 2022 season, further expanding the reach of the bittersweet romance between former step-siblings who used to date.
