I've done the TI many times between doing my 15 over the past two days, and also helping a lot of my friends do it. I've probably done over 100 by now. Still haven't seen that second round. But that tool is interesting, it certainly has higher base stats than what I have.
That being said, its name and border are gold/yellow. I'll tell you something even more interesting, I have a gold/yellow blade that is better than the Shichiseiken. The Shichiseiken has the red "aura" coming off of it, while this superior one has the average yellow.
I think perhaps how we have been judging these items might change because what we know and what we are seeing isn't matching. While that is a superior gourd, I don't think it's red. But this is just speculation.
