Danger Do Not Mix! The Chaotic Rhapsody of the Gyaru Summoner and the Stoic Swordsman

Synopsis

Through relentless training, Vice became the strongest swordsman in the world. On the other side, there's Dance, a demon who visits human settlements every chance she gets, causing absolute chaos by summoning magical beasts. Meeting on the battlefield time and time again, the two have formed a literal fated rivalry... which mostly involves getting along (?) by bickering constantly. Then one day, they are hit by a mysterious spell and simultaneously transported to another world! Stripped of the magic they could normally use in their original world, they find themselves in a desperate, life-or-death crisis. But suddenly, Dance's summoning magic somehow reacts to Vice...?! Even in a brand-new world, the two carry on with their usual back-and-forth banter. However, as they overcome one crisis after another together, something begins to shift in their relationship.
