Samantha: hmmmmm... guess Ill have to look down a different avenue for that.
Salvador: *Stomps out of the time distorted room and attempts to lodge the Zanpakutō into the ground with a throw.* This bloody sword was a fucking waste of time! Why the hell should [i]I[/i] have to prove myself to an [i]object?![/i]
Samantha: *Pulls a gun out from a pocket dimension and shoots Salvador in the foot from where I'm standing.* 
Salvador: *Jumps and starts hopping around on one foot.* [b]Ahhggg[/b]! For fucks sake why did you do that?!
Samantha: *Holds up a finger for each reason.* Ego, Language, and Temper. We are currently guests here.
Salvador: *Grumbles but doesn't give a retort.*

That's called a zanpakuto, it's both a separate entity and a part of your soul. If you're not able to learn its name, you may as well quit now.
