We know that Experience and Talent are needed to unlock Path



And it seems Talent is more important than Experience as for example Johan doesn't really have that much experience. But he's has overwhelming talent 



And Goo and Gun come just after Johan in terms of talent 

  
I mean Goo created in 1hr what no one else in the continent could create. That shows his talent 

  
And there's also another key thing which is Conviction

  
But Conviction can come in different forms

  
Gap's conviction was to protect his friends 

  
Jinyoung's Conviction i guess you can say was to protect and save his nephew 

  
Gitae's conviction is to become the King of the Underworld by basically dominating everyone or making them obedient 



Then there's also Gun, Johan, Daniel and James 



So you could say Goo's conviction is to never lose to Gun again. Or to be the one to kill Gun. Or to defeat TUI Gun who he lost to 

  
You get what I'm saying? Their convictions are different 

  
So onto the other point 

  
Daniel basically used his copy and senses to create his path 

  
Daniel can instinctively read his opponent's intentions because of his senses. Gun said it's because of his senses that Daniel can copy 

  
Daniel combined his experience of copying countless moves and fully enhanced senses to create his path

  
Johan used his copy in a different way to unlock his path. Johan made it so that his attacks are a collection of various moves that he has copied. By copying the moves of other fighters and making them his own. That's how Johan unlocked his path

  
Now when it comes to Goo as you can see by the panels in the post Paecheon has pointed out that Goo can predict Sword arcs or trajectories. I believe he used that skill of his to create his path which is the Goo Kim Style Moonlight 

  
The same way Daniel and Johan used their skills 

  
There's no 5th form because the Sword arcs/trajectories collide after the 4th form. But since Goo can predict them he can overcome it

  
Daniel: Senses and Copy skill. Combined them to create his path 

  
Johan: Copy skill. Copied countless moves and made them his own to create his path 

  
Goo: Sword arc/trajectory prediction. Used that to create new techniques which broke through them because he can predict the sword arcs



It is something solely unique to Goo. A Goo Kim original. It is literally called Goo Kim Style Moonlight. I believe it meets the requirements to be considered a path 

  


Doesn't this basically confirm that Goo Kim Style Moonlight is Goo's Path?
