Was re-reading the last manga. Something was a little off about Hagomoru in it but I can't really place it.
1: "Now I only have to retrieve all of you" Kinda auspicious.
2: Last scan he had a smirk more than a smile.
3: Hashirama seems a little concerned about something (could just be Madara)
Only a theory which even I do not believe to be likely all things considered...however Kishi is the Troll King.
Might Hagomoru become the final-er villain?
