Synopsis: Do Not Mix These Two! The Gal Summoner and the Straight‑Laced Swordsman’s Crazy Rondo

After relentless training, Weiss has become the strongest swordsman in the world. Meanwhile, the demon girl Dance loves visiting human settlements just to summon magical beasts and throw everything into chaos. The two repeatedly clash on the battlefield, bickering like frenemies every time they meet, and have built up a very literal love‑hate rivalry. One day, they’re both caught in a mysterious spell and transported together to another world. There, the magic they relied on back home no longer works, leaving them in deadly danger—until Dance’s summoning spell suddenly reacts to Weiss instead. Even in a new world, they never stop trading barbs and snappy comebacks. But as they survive crisis after crisis side by side, something begins to change in the relationship between this disaster‑prone pair.
