Here's what I found:
In chapter 61 around pg19, Kaname bit Yuki roughly so that blood from her neck was all over her
*which came first?
*this is reliant on the accuracy of the meaning of the translation, so I can be wrong..
in chapter 63-28, Aido explains the process of the hooded woman's sacrifice:
1. the woman gave her blood to the hunters
2. and "lastly", she tore her heart and threw it to the furnace.
then in chapter 64-07, an ancestor hunter also explains the hooded woman's sacrifice:
2. "after that", she gave her blood
ah, maybe it's just the use of the words "lastly", "after that"..? anyway for me the historical version (aido's narrative) makes more sense as it seems a real pain to distribute blood after her heart was torn.However, the hunters also are more credible ( they were there when it happened) a pureblood with a heart ripped off can still walk around, only their power is "low": this what happened to shizuka when kaname tore her heart, she still lived for a few moments before breaking (chapter20). Also what happened to Hanadagi when kaname stabbed him with an antivampire weapon, he was still able to talk for a while (chapter67)
but still, a short while means 5-10minutes at most...it says here the woman "walk around" giving her blood. what do you think?
antivampire weapons have some sort of crackle reaction to them, here are examples:
- Zero holding artemis –chapter 6-30
Kaname grabbing yuki’s artemis –chapter 30-21
Pureblood yuki holding artemis for first time –chapter 41 -21
but in chapter one at the first chapter the crackle effect is not present:
