Akasha the woman who set Moka's future. From Rosario Vampire manga season 2.
The Shinso Blood by the way has similar properties to Vampire Blood but it is much more powerful. It could be considered a very dangerous weapon depending on how you use it. The blood must be transferred you cannot however inherit this blood, it must be transferred from the person who has the blood. In this case you could say it must be injected to your body so technically speaking Tsukune currently has Shinso blood inside his blood streams.
