 Well there was some traveling across the nations(while she was carrying) due to her exile from the clan. Reason for exile is that she was promised to the head of another clan in a political marriage, but she fell for a member of the Kajiya clan who then left her the moment it became clear that she was pregnant, leaving her to face the wrath of her family alone. Needless to say, it didn't go over very well, and for her dishonorable actions, she was banished form the clan, and effectively from Mizu no Kuni. I guess this is the another instance of me assuming things come across without saying them or thinking more than I actually write.[/quote]
So, while she was still pregnant she was banished from the clan (and the country). Wouldn't it be more logical for her to have given birth in Gobi instead of Kiri, which she had been banished from?

The way I see it, probably not since they'll be going in very different directions, I think, in regards to how they'll apply their work. Kajiya sealing technique involves working in the seals during the forging process, using a mixture of chakra and specialized seals to get the best results. Since Tatsuya doesn't have that skill yet, he'll be trying to apply the seals after gee's made the weapon, which'll lead to them having to be redone after continuous use if painted on, and only being useful for a certain amount of time if engraved on the blade itself(since once the seal has been deformed, it'll be useless forever).

So, how has the character gained any knowledge about the Kajiya-clan's sealing techniques?
