What Mahou Sentai Magiranger vs. Dekaranger is
You assemble a ragtag team of Magic Rangers when a dimensional quake lets loose an army of space villains—and then a rival squad kicks in the door, decked out in futuristic badges. Director Katsuya Watanabe’s crossover confronts the heroes with their own rulebook: what happens when justice wears two different uniforms. It leaves you watching heroes relearn the alphabet of teamwork.
