It has nothing tondo with Xenoblade. I have been using the name Xenosaiga long before Xenoblade was even released.
There is a game called "Xenosaga" and it is amazing but I was just joking about how I feel when I see a cool name like that.
In all honesty Kos-Mos had no effect on my name either. Was not aware of Xenosaga at the time of the choosing of my name. Honestly I wound have possibly rethought that if I had known...
