Help me!! :((

Since the inazuma trailer was out, I want gorou so bad that I must save primogems for him but He's still in the process and some leakers said that he's a 5 star and some said he's a 4 star, and no announcements of his banner too and 1st anniversary is coming up.

Should i pull for kazuha (I'm guaranteed tho) and pull for gorou if ever his banner comes or save primos for gorou?

I want kazuha too :(( but i can't choose!
