Tatsua,How does her blood absorb the blood of others, and in what way is it poisonous to others? Rank your techniques please.[/quote]

The blood has to be touching (eww). I can't just touch people and be all like "Hey, I gotchur blood.", rather I would have to cut my finger and tenderly shove it into somebodies open wound.

In what way is it poisonous? The only way, really. It's poisonous.
