Aaron | Aria
Aaron (アルス, Ars) is one of two playable characters in Rune Factory 2: A Fantasy Harvest Moon.
He is the child of Kyle and whichever bachelorette that Kyle married. Aaron is very determined, kind, stubborn and apparently a bad liar, like Kyle.
Aaron looks similar to Aria, except that his teeth is shown on the artwork.
Aaron is only playable in the 2nd Generation and only if you chose a son in the first generation. In the 2nd generation, he is portrayed as a 7 year-old child who is looking for his father and will do anything to find him.
Although they are never shown together during gameplay, Aria and Aaron are twins, as shown together in the second opening video.
