Weapon:
The Lionheart or the Exeter - Probably Exeter truth be told, but the Lionheart is a sword, and I like swords... It's too bad Selphie doesn't have sword-chucks.

GFs:
Ifrit - Fire! ^^ >.> And ammo...
Alexander - Holy damage
Brothers - Earth damage
Pandemona - Wind Damage
Bahamut - Mega Flare, seriously, is there anything else necessary?

Place of Residence:

The Ragnorok, parked forever at the research station while I run around killing monsters >.>
