Looking good Derren. One thing that you've brought to my attention is that we would all be ancient if we were in Nobunaga's squad. Now we can either choose to simply ignore this :P or we can be considered quite old. We don't have to be Yamamoto level but think similar to Koryaku but a bit older. A third option is available though that if people want to be the descendants of the original squad members that would be cool, plus it means they can be seen without masks so could add another dimension. 

In terms of your CS Derren you don't have to change your origin since you've already done it, just thought the descendant thing fits her really well. Power level she is great so unless you want to add anything else I would say accepted :)
