乱马1/2 超无差别决战！乱马队VS传说的凤凰

One day, Kuno Tatewaki obtains an egg that hatches a chick capable of unleashing the invincible sword technique known as the "Phoenix Sword." Due to interference from Saotome Ranma, the newly hatched chick recognizes him as an enemy and relentlessly attacks both Ranma and Kuno. Since it would take a hundred years for the chick to leave the nest naturally, Ranma and his friends decide to confront it using a special pill that accelerates its growth. This story revolves around the Phoenix chick from an original episode, featuring regular characters such as Hibiki Ryoga, Tendo Akane, and Shampoo.
