Aika is a free-to-play massively multiplayer online role playing game. In its fantasy world, the demon-like Zerecas have corrupted and enslaved the monsters and creatures in the land in their plan to rid the world of all Humans. The goddess Aika created the fairy-like Prans to ally with the Humans against the Zereca. Will the humans and their new allies defeat their evil attackers or be torn apart by internal war?

Besides boasting the standard MMO features like questing, dungeon-running and crafting, Aika is heavily focused on PvP features. Aika is optimized for large scale Nation Wars where thousands of players can fight at one time. In Aika you can: fight for control over your nation during a Castle Siege, attack an enemy nation to capture their magical artifacts to boost your nation's power, and participate in a variety of exciting PvP games in the battlegrounds.
