As an investigator of the Disaster Investigation Department, you are dispatched to Black Mist Island, the epicenter of all disasters, to uncover the truth behind the apocalypse. Here, tens of thousands of monsters are created and sent to the world. You must find a way to eliminate them, stop the disaster from worsening, and investigate its truth. Although the final truth may be unexpected, as the strongest warrior, you must first eliminate the monsters.

You have access to a variety of weapons, each with its own unique skills. Additionally, you can deploy various defense buildings and summon soldiers as powerful as you to help eliminate the monsters.
