What is hiruzen doing??

[Naruto99Uzumaki]

From the beginning the edo tensei took like maximum 3 min to restore , now its taking almost 4 chapter for hiruzen to wake up?

 

[Princessu Kaaantchan]

He's about to wake up and solo.

 

[Sir Blades]

He is analyzing the situation.

 

[Penguin]

Hiruzen is looking for Orochimaru. He will solo soon.

 

[Parrish]

He's kinda poopy compared to the other Hokages, so I doubt he does anything.

 

[minato23]

Stroking his **** leave him alone

 

[Hypemaster]

Chilling at the leaf village

Hiruzen's Master plan

 

[Overrated]

Orochimaru scooped him up and is restoring him to his prime.

 

[startup97]

Regenerating. He'll come back to solo!

 

[RicardoA]

Everything the others said is correct, i only have to add one thing.
You realise this is a manga not real life event, he appears when Kishi decides he has too. It doesn't matter how long it takes to regenerate, that's a detail that no one should care.
