Disclaimer: I do not own My Hero Academia and One Piece.

As the battle begins, Luffy was charging at me that I have to quickly dodge it but he hits me by stretching his left leg to my face. Luckily, I stumbled. Does this mean that his body is made out of rubber? I was surprised that his quirk is rubber and I thought that it would be impossible to defeat him against my quirk, One For All. I wasted two minutes by seeing one of Luffy's attacks with each dodge and it is possible that he can stretch his arms rather than his legs. I moved forward to attack him but he dodges it thus attacking me from behind with a kick.

"Too slow." Luffy mocked me.

"I won't lose!" I yelled angrily.

I came up with a plan to knock Luffy out of the battle ring. I focused on One For All's power into one or two of my fingers, I release tremendous amounts of concentrated force on him but little to none have affected him that have shocked me. It only pushes him away from me. I did it again three times by jumping in the air that I managed to damage him a little but that wasn't enough to injure him severely. Using his stretching capacity to drastically augment the speed at which he brings his fists back and forth, Luffy launches torrent of consecutive punches at super high speeds. The hits land so fast that dozens of punches appear to connect simultaneously. I blocked it but my arm aches from his punches that I have no choice but to become open. However, he immediately stops. A standard straight punch, augmented with stretching, it hits me in the gut thus sending me back a bit. My stomach is in pain as his punch is very powerful. I threw an uppercut to release the power upward. It wasn't strong enough and he threw consecutive punches at me again but I dodged it. I used One For All: Full Cowl to surpass him or I think it will. This technique allows me to activate up to 20% of One For All throughout my body, letting the power course and flow through me instead of concentrating it in one location. Activating this technique gives me enhanced strength, speed, mobility, and agility. It also prevents me from breaking my bones whenever I uses One For All. Luffy is staring at me surprisingly upon seeing this but he shrug it off that he thought that I still wasn't strong enough to defeat him. Luffy attacks me but I pushed his left arm away to hit him multiple times. He is severely injured from the hitting but he still fights. He stops to tell me something.

"There is no way that you can defeat me. Why? Because my body is made of rubber!" Luffy yells at me angrily.

"He reminds me of Kacchan. No wonder he is this angry..." I thought surprisingly.

"I'm gonna be King of the Pirates!" He said angrily.

"I'm gonna push over my limit." I thought confidently.

I used One For All: Full Cowl - 100% and I have a bad feeling that I might become severely injured from using this but this is the only way to show Luffy my true potential. I activate One For All to its fullest extent throughout the entirety of my body, granting me a tremendous boost in strength and speed. Luffy is shocked from seeing this.
