[[WMG: One character of Utawarerumono 2 is Aruru several years later.]]
And she's using Gachatara as a scarf.
** Well, it's plausible, the first adventure wasn't clear in about how many Yamagiras there were in the world, for all we know they all came from that single village and later Hakuoro's Kingdom, and those set of clothes seems to be exclusive of Eruru and Aruru's relatives.

[[WMG: Kuon, female lead of Utawarerumono 2, is the daughter of Hakuoro and Yuzuha.]]

She is Yamagira and has a look similar to Yuzuha. As baby was presented in all versions of the game, it's gender wasn't specified and second part takes place about 15-20 years after the end of the first game (if reoccurring characters look is any indication), it could be possible.
* [[spoiler: Confirmed in the latter part of the game]].
