RPG gamer through the multiverse!

I have a series of questions to ask you all regarding how I should progress yuuji's training arc, I'm already having Garp train his body and awaken his haki.

Now he will unlock armament and observation haki, but for conquerors haki how should he awaken it?

(Comment on this parentheses how he should go about unlocking it)

Also I want to complete yuuji's training by having him take down a warlord or really bad guy.

(Which warlord or bad guy should Yuuji take down? Comment on this parentheses)

Also which part in the story is Yuuji in? Because I want him to meet luffy and help him out at some point.

(Comment where in the story will Yuuji be sent to help luffy)

And finally should I have an OC celestial dragon who is actually nice? I want to make a celestial dragon that is that last of her line and wants to go with Yuuji at the end of his training arc.

(Should I make a nice celestial dragon OC, comment your answer here)

I'll post the results next Saturday.
