Based on a colorful, bright, and cheerful world, Asda Story features its “Soul Mate System”, the unique party system. “Soul Mate” can be made between two players, and when they decide to get together as “Soul Mates”, the couple is then able to wear their own unique costumes, and use unique skills. Furthermore, between “Soul Mates” one player can use the other player’s character during that player’s absence and all of the achievement during that substitutive game play will be saved in a “soul stone”. The owner of the character can open the soul stone, and all the achievement acquired will be restored to the character’s inventory or ability points. In addition, items like the “soul mate apple” help low level mates to get assistant from their partner.
