Okay, here:

Weapon: Siefer's Gunblade. Why? Because it looks cooler than Sqaull's gunblade.

Place to Live: Deling City because it is a pretty cool lookin' town.

GF's:
Gravier(because he is the ultimate GF)

Diablo(his name sez it all)

Bahamut (because Bahamut is one of my favorites, plus his attack is cool)

Eden (because he is bad ass.It's just that his attack is long as hell)

Alexander (because he is a metal/robot monster thing)

Doomtrain (becuse Doomtrain inflicts a lot of status effects on people)
