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

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
