You can only pick what I say you can pick, this is mainly for one piece since I'm only one episode 131 which I am watching right now. Similar with the other anime's that I haven't finished (not counting mha, I've finished the anime)

One piece! Imma be with the straw hats are either the red haired pirates

One piece - I choose Cross Guild
