Everyone has a soulmate mark.

And yours was on your left shoulder and it's the number 4.

You're a soul reaper that's in the 8th squad... And you have your Bankai and Shikai... So you get sent on more missions then other squad members.

Today You got sent to Las Noches.. And as you were walking through the hall... When you got knocked out... And when you woke up you didn't have a shirt on... And someone drew a red circle around your soulmate mark.. With blood but it wasn't your blood...
