The Legend of Heroes: Zero no Kiseki KAI – a role-playing adventure in the mechanical region of Crossbelle. The plot revolves around the Special Assistance Department, which includes 4 different characters trying to overcome the obstacles that define their way of life. This part is a re-release of the original game, providing support for 60 frames per second, high quality resolution and improved sound.

There is a high-speed mode that will allow the player to instantly move between story events and quickly go through the story. It will also require you to participate in battles, but they take place at four times the speed, and the collisions become easier. The user will have to control a squad of 4 heroes: rookie agent Lloyd Bannings, mayor's granddaughter Ali McDowell, sorceress Tio Plato and security guard Randy Orlando. Each of them has a unique backstory and role in the journey.

The action begins with a story about pressure from the Empire of Erebon and the Republic of Calvard, which is why ordinary residents have to go through difficult times. The corrupt government is completely mired in bribes, mafia affairs and crimes, which makes life difficult for the city. The Special Support Team tries to solve most of the difficulties using all the capabilities they have.
