Kaito, Mei, Ryu, and Yuna were all attending the prestigious academy for magic, where they were learning to control and harness the power of the elements. Each of them had been chosen by the academy's master to study and train in the art of magic, but little did they know that destiny had something far greater in store for them.
One day, as they were all practicing their spells, they noticed a strange energy emanating from deep within the academy's library. Curiosity getting the better of them, they decided to investigate, and what they found was beyond anything they could have imagined.
As they entered the library, they were greeted by a strange, glowing orb that seemed to be pulsing with energy. As they approached it, the orb suddenly burst open, revealing four gems of different colors - red, blue, green, and yellow. The gems began to glow and hover in the air, before shooting towards Kaito, Mei, Ryu, and Yuna.
As they caught the gems, they felt a sudden surge of power coursing through their bodies, and a voice boomed in their minds, "You have been chosen by destiny to become the guardians of the elements. Fire, water, earth, and air - these are your domains. Use your powers wisely, for the fate of the world rests in your hands."
Stunned and bewildered, the four students soon realized that they had been chosen to become the Elemental Heroes, the guardians of the elements who were destined to protect the world from an ancient evil.
As they left the library, they were ambushed by a group of Shadow Knights, who had been sent by Zephyr to capture the gems and prevent the Elemental Heroes from fulfilling their destiny. But with their newfound powers, the heroes were able to fend off the attackers and escape.
Now on the run from Zephyr and his minions, the Elemental Heroes must learn to master their powers and work together to defeat their enemies. Their journey will take them to far-off lands, where they will encounter new friends and allies, as well as dangerous foes and treacherous obstacles.
But no matter what lies ahead, the heroes know that they must stay true to their destiny and fight to protect the world they love. For they are the Elemental Heroes, the guardians of the elements, and their time has come to awaken and fulfill their destiny.
