Ayakashi: Ghost Guild is a free role-playing or card battle game with a rich story line of the battles with ghosts and other agents. As a ghost agent, players try to come to grips with the mysterious events occurring around them. These events are being triggered by legendary creatures with enigmatic power beyond comprehension. Players must attempt to gain control of ghosts and bring them under their power, changing them to a demon. Players can obtain demons as they make progress through the story, and they can get rare demons by summoning them. In addition, players can get rare demons by collecting all the sealed stones in the story, which will release a rare demon.
As a ghost agent, the player has the chance to recruit ghosts to serve them as a demon after they have been defeated. The negotiation is not guaranteed to go well, and there is a chance the ghost will reject the offer so the player may have to rely on luck.
Once the player has obtained a demon, they can be enhanced by fusing them with other demons. Leveling up your demons will improve their abilities and increase particular skill levels, which is crucial in battling other players.
