toad summoners theory

[GOD2U]

Alright so when naruto signed the toad contract there were 4-5 other names. We've found out that two of those were minato and jiraiya; however, who are the other 2?. My theory is that the other names on the contract is the sage of six paths and his younger son. So if somebody could decipher those names we'll know who the sage of six paths and his son were and their names.

P.S.
Sorry I can't seem to be able to copy the link URL and put the picture on here. I know how but the codes are too long and it won't let me post the pic.

Why would someone as OP as the sage need a bunch of frogs to get in his way?

why does everyone overthink the smallest unimportant shit
but become total morons when it comes to the larger relevant shit ?
