Yūichirō Momose, widely recognized as the main scenario writer for the popular Hypnosis Mic franchise, has announced a brand new multimedia project titled “Datewars.” The announcement, made on Thursday, introduces a unique concept centered around “criminal girls fighting time-traveling terrorists using songs from the 70s to the 2000s”.
The new “timeless music IP” promises an intriguing blend of action, music, and a compelling narrative, building on Momose’s established reputation for creating engaging worlds and intricate character dynamics.
Diving into the “Datewars” Concept
“Datewars” is positioned as a distinct intellectual property that combines elements of musical combat with a time-traveling premise. At its core, the franchise will feature “criminal girls” who utilize the power of music from specific eras—spanning from the 1970s to the 2000s—to combat adversaries described as “time-traveling terrorists”. This imaginative setup suggests a vibrant world with a heavy emphasis on nostalgic musical themes, likely appealing to a broad audience across different generations.
The project is designed as a “timeless music IP,” indicating a strong focus on its musical component and potential for various adaptations across different media.
Key Creative Team Behind “Datewars”
Momose is joined by a talented creative team to bring “Datewars” to life:
- Hanaharu Naruko will serve as the character designer. Naruko is known for their work on titles such as Kamichu, Gargantia on the Verdurous Planet, and Kandagawa Jet Girls. Their distinct art style is expected to shape the visual identity of the “criminal girls” and other characters within the “Datewars” universe.
- Mino is on board as the music producer, video creator, and music commentator. Mino’s multifaceted role highlights the critical importance of music and visual presentation to the core concept of “Datewars,” ensuring a cohesive and immersive experience.
