Toukiden is a third-person monster hunting game which employs groups of players or NPCs fighting together against various monsters during quests. Each player can customize their choice of weapons, armor and skills. Special abilities can be obtained through the usage of souls, or mitama, which can be collected during the progress of the game. These mitama can level up by gaining experience from battles, or by paying a certain sum of haku. Different mitama have abilities with various characteristics, and can be categorised into various groups such as offensive, defensive, or recovery mitama. Upon slaying a monster, the players or NPCs can "purify" the monster, which collects items useful in upgrading weapons and armor. Monsters fall into the categories of small and large oni, with large oni being the boss-type enemies within the game.
Players can engage in missions co-operatively via an ad-hoc WiFi connection, or over the internet. Additional missions are available in the form of downloadable content.[11]
