START OS S2

Kai, fueled by the inspiration drawn from the resilience of humanity, makes a decisive choice. He decides to return to his world and face the challenges that await.

Using the powers gained from the Tower of Challenges, Kai opens a dimensional portal, embarking on a journey back to his homeland.

Upon arrival, Kai is shocked to witness the transformed state of his world. The once familiar landscapes are now overrun with waves of monstrous creatures emerging from mysterious portals.

Portals of varying sizes and colors scatter across the horizon, each one spawning monsters of different strengths. The threat level is classified from F grade to Ace grade, with legendary creatures posing the most formidable challenges.
