Who made the My Sweet Marriage to My Ex-Nemesis manga and what the story is
The manga is drawn by Shīme, adapting the light novels by Toshimichi Uzō under Kadokawa’s Dengeki Bunko imprint. Uzō launched the series in October 2023 with illustrations by Kewi Hayashi, and volume four shipped in August 2025. That timeline gives the comic a solid roadmap as Shīme translates prose beats into panel rhythm.
Roshi Saigawa and Ritsuka Nagira were once bitter rivals inside opposing groups of superpowered warriors. Now they are married, swapping duels for chores and schemes for dates. Old rivalries, buried secrets, and reflexive one-upmanship complicate their vows, turning newlywed life into a brisk mix of domestic comedy and lingering danger.
- Protagonists: Roshi and Ritsuka, former nemeses now committed partners learning married trust.
- Core hook: sworn enemies become sworn spouses, with heat and humor driving the day-to-day.
- Story energy: laugh-out-loud mishaps balanced by heartfelt moments and tender compromises.
- Ongoing tension: resurfacing grudges blur lines between rivalry and romance.
- Publication trail: Shīme’s adaptation began in November 2024, and Kadokawa issued volume one in June 2025.
- Source lineage: Toshimichi Uzō’s light novels underpin world rules, character arcs, and tone.
- Genre fit: a sharp enemies to lovers rom-com manga that plays with superpowered habits at home.
- Audience appeal: couples banter, soft romance, and action-tinted gags in equal measure.
