Okay, but Imma readin it later, also if you are curious about the Black Blood in the library or the story:.

The Black Blood or Type X (Cross) is a newtype of blood and is notable of its very black color who never turns red, Cadenza has Black Blood and she confesses that is the most healthiest and rarest type, however, if a normal, non-athletic and passive human has through blood donation, drinks or touches it, it will cause either a corrosive effect on him/her or even the death of a person leaving only its bones. Geminia has also this, possibly Dr. Arc too due to his deadly white body color but ironically he is passive and a non-combative person.
