Two Gunshot Staring each other.
Luffy knows how much strong Charlotte Katakuri aka Dogtooth is, after exchanging the punch before. He is quite serious for this fight.

What is this? Luffy is laying down covered in blood all over. Still he is muttering something. "Son of Bitch I won't............."(coughs blood).
Wait what is this, Dogtooth is also laying down the ground same condition as Luffy's.

Dogtooth: "Luffy you are persistent. Give up. But I admire you are strong. You have to be stopped now. You are gonna a big threat to mom. So you have to...... He couldn't stand as he tried once again. (coughs blood)." He saw someone is coming near to Straw Hat. But he only could see black shoes.......again he coughs.

Both of them are staring without saying word but Dogtooth exactly knows what is going to happen. He already saw short portion of future. HisKenbunshoku Haki was activated back awhile.

Dogtooth : Luffy its not wise to engage on fight. And I think you also know that.

Luffy : I know. But I can't allow you to lay a finger on my nakamas. So I have to stop you here now.

Dogtooth: Ok I will withdraw from this fight. I won't follow too. But next time when I see you It will be your last breath.

Luffy : I will wait for that day.

Dogtooth : Wait for a while. One of your nakama will be here soon.
Luffy looks confused.
