This is a great story it's well detailed and fun to read gope you can update this story in the future and not let this story to retire for good

Guessing Shukaku's test will be for Naruto to find him or something like that. Or it could be he gives him nightmares like he did to Gaara and Naruto has to endure them.
So far Naruto has 4 keys:
Ichibi-Shukaku (Inactive)
Sanbi-Isobu (Active)
Gobi-Kokuo (Active)
From Naruto's words, "Straight up fight? Test of wits? Working under pressure?..." I'm going to assume those were related to the tests he's already had to endure. Isobu and Kokuo don't seem like the bull-headed types which leads me to believe his unknown key was the "straight up fight" one. 3 Bijuu come to mind for that IMO: Son Goku, Gyuuki, or Kurama. Just going to rule Kurama out immediately as it'd feel kinda cheap for Naruto to have the most powerful key this early. Out of the remaining two I'm going to guess Gyuuki as it'd seem to enjoy a brawl more than Son would IMO.
Hope this updates soon as I'd hate for a good fic like this to end up dead.

Great story! Can't wait to read the next chapter!

I hope that those keys that he has in his hands don't cause destruction because normally Celestial keys are not related to anything in destruction but how will Lucy deal with Naruto, and will he be a good guy or a bad guy in this story.

Great story make more please

Well that is an unique twist about first gate

please update
