An asymmetrical action single-player game. At the start of battle, players control a hero with extraordinary powers. Upon defeat, the hero randomly transforms into a monster, while the monster that lands the final blow becomes the hero and continues the fight. Ultimately, players must challenge a boss controlled by three ghosts, or control the boss with two ghosts to meet the hero's challenge. 【Death Is Not the End】 The death of a hero does not mean the end of the game. Ghosts who defeat heroes are reborn as new heroes. Defeated heroes become spirit servants controlled by demons until they defeat the hero and are resurrected. 【Equipment Combinations】 Heroes can collect teeth as loot to purchase more powerful equipment and skills. Combine diverse weapons, equipment, and skills to create different combat styles. You can choose to use ranged skills for sustained damage or employ sharp melee attacks to overwhelm enemies. Combat strategy and style are entirely up to your choices. 【Monster Evolution】 Loyal servants can receive blessings from demons. Monsters can consume psionic energy to evolve into one of two new forms, easily defeating heroes with more powerful dark forces. 【Boss Battle】 As the victory condition, the hero will challenge a boss controlled by three ghosts. If the hero successfully defeats the boss within three attempts, they win the game. Conversely, if the hero fails in the third attempt, the three ghosts share the victory.
