If this has been done before, my apologies and mod, please rease this thread. I always have this thought. How exactly do you become a master of a Lord summon? For example, if Oro somehow gets his hands on the scroll of the snail or the frog and he makes a blood contract, would the Lord summon obey him since Oro is the one that summoned him/her and already made a blood contract with them? Can A lord summon cancel the blood contract if he doesn't like the current owner? Would he has to fight the owner to see if he is worthy of the ownership? Would both need to be similar in charactersitics? As Oro's, Jiraiya's and Tsunade's personality are reflected in their summon. or would a Summon immitates the owners characteristics? For example. Oro was able to summon Manda, but for some reason, Sarutobi didn't have a problem with Manda, and we know that Manda is ruthless and requires sacrifices? Was Sarutobi aware of that? Did he think it was worth the sacrifices? Did he turned a blind eye like he did with Oro? Could it be that the Sannin had to fight the summon in order to be worthy of the ownership? The only problem i see with this is that i think i saw a couple of names before Jiraiya and Yondaime's blood contracts, but the question still remain, what's necessary to be a owner and get accepted by the Lord Summon? Then, there is this part, what would happen if a scroll is destroyed or if a seal is put in them? Would any of the sannin would be able to summon their Lord summons, even though they know the handseals for it? If they were able to summoned them, do you think they would listen to their owners, even though their blood contracts no longer exist? Can one be owner of different animals at the same time? Can Oro summon Gamabunta and the snail if he mananged to sign a blood contract, and seal Jiraiya's Tsunade's and Naruto's blood contract?
