The Sevpons : Rise Of The Weapons.

The story begins with Ryu practicing for a marathon, where his brother Tony urges him to come home for lunch. Ryu expresses his desire to join the EX Agency, but their mother is concerned about the admission fee. After learning that the marathon's first prize is $100,000, Ryu vows to win it to secure their admission. He wins the marathon and uses the prize money to buy scholarships for himself and Tony, allowing them to attend the EX Agency.

Upon arriving at the EX Agency, Ryu and Tony meet new friends: Kai and Jin. They learn about their weapon training classes and select their primary and secondary weapons. During lunch, they hear rumors from a boy named Wei about a secret weapon hidden in a cave, but Ryu warns against breaking the rules.

As they continue their training, the group prepares for a monthly test. They discover that Wei has been researching the cave and the rumors surrounding it. Wei reveals that several students have gone missing, prompting the group to investigate the cave at night. They find themselves in a dangerous situation when they encounter guards and a mysterious figure named Lei, who seeks a powerful weapon.

Ryu and his friends fight against the guards, and during the chaos, Ryu discovers a legendary sword. However, Lei captures them, intending to use their blood to awaken the weapon's power. With teamwork, Ryu, Tony, and their friends manage to defeat Lei and escape with the other captured students.

After their adventure, they wake up in a hospital, where Master Feng praises them for their bravery. The group learns that the cave has been sealed, and the fate of the legendary weapon remains unknown. As they prepare for their next test, they continue to train and develop their unique weapon abilities.

The story ends with the group discovering a portal that leads to another adventure, hinting at more challenges and mysteries to come.
