AIKA Online is a free-to-play MMORPG published by HanbitSoft in South Korea, CBM Interactive in the global market, GameNet in Russia, HAPPYTUK in Taiwan and Ongame in Brazil.

The game is optimized for large-scale Nation Wars where thousands of players can fight at one time in massive combat.

As time went on, however, human ambition led to the destruction of the land, greatly angering the goddess.

In response, she created a race of demons called Zereca that drew from her powers to punish the humans.

To salvage her second creation, she told the Human prophet Giovanni to gather his people to a region known as Lakia.

Each civilian which is Legion (Guild) Master can fight over Lord Marshal position on Castle Siege War every Saturday.

Alliance doesn't have automated targeting, just like same citizen but with flag above character nickname, with exception of adding as friend and guild invitation.
