Bleach: The Sanguine Espada, Revised

"Even if you speak truth, I fail to see the use of a heart that cannot feel." "I don't think it's a matter of use. 'For something to touch your heart, your heart must first be open to touch.'" "You sound... knowledgeable." "Oh, I didn't make that up. A friend said it to me a while ago, but I still don't think I totally get it." ((OC-centric)Summary in progress)
