Toukiden: The Age of Demons is a third-person monster hunting game where groups of players or NPCs fight alongside various monsters during quests. Each player can customize their choice of weapons, armor and skills. Special abilities can be obtained by using souls or mitamas, which can be collected as the game progresses. These mitams can be leveled up by gaining experience in battles or by paying a certain amount of Haku. Different mitams have abilities with different characteristics and can be divided into different groups such as offensive, defensive or recovery mitams. By killing a monster, players or NPCs can "purify" the monster, which collects items useful for upgrading weapons and armor. Monsters are divided into small and large oni, with large oni being the boss enemies in the game.
