this may be something that is of little revelance but remember when orochimaru attacked konoha and summoned the 1st,2nd and tried to summon the 4th hokage but the third stoped the summoning from happening.What i wanted to know is how he go the 4th's soul when it was lost forever when he used the sealing technique from the explanation the god of death eats your soul wich is lost forever and when he explains the summoning of the past hokages he says he binds there soul to another dead body lol i know this is old but its also interesting
