How Mitsuki's older self will come into play.

[Reviewing Logic]

yeah I can see him dying

since they can't have to of them running around especially when the other Mitsuki grows old via timeskip

he is basically there for some plot death

 

[lndra]

Maybe he will teach mitsuki something

Something Orochimaru can't? Who do you think taught Mitsuki lol

 

[Chikombo]

Where is this from?
