In the Straw Hat Crew, I Get Stronger by Making People Lose Their Cool

After transmigrating to the world of One Piece,

Gu Yu awakened an Emotion System that granted him skills and weapons whenever he made someone lose their cool.

After defeating Buggy the Clown,

Gu Yu accepted Luffy's invitation and joined the Straw Hat Pirates.

From then on, a pirate crew that struck terror into the hearts of both the Marines and pirates appeared on the Grand Line.

They weren't just powerful. They also had a knack for driving people to the brink.

"Mihawk, have you ever heard of a sword technique called 'One Hundred Percent Catching a Blade Barehanded'?"

"Crocodile! I have my doubts about your gender and your relationship with Whitebeard."

"Akainu! I heard you once ordered a refugee ship full of civilians shelled so the Celestial Dragons wouldn't have to wipe their feet on the ground!"

During the final battle,

when faced with Imu's world-ending weapon,

Gu Yu grinned wickedly and whipped out his Noble Phantasm for Destroying Stars.
