alright. I've seen all the episodes and have read the manga several times. Maybe this has already been discussed, but how is it that oro can still summon Manda and those other snakes. I mean it requires a blood contract and oro is in someone else's body. Now if his blood is the key to his contracts, how can he still summon using someone else's blood. Now i have several theories on this. but i'd like to hear what other people think.
