I, Uchiha Sasuke, Get a Swagger System from the Start

A fanfiction writer dies suddenly from overwork. When he wakes up, he has become Uchiha Sasuke.

He gets a Show-Off-to-Get-Strong System.

First mission in the Land of Waves: "Momochi Zabuza? You're going to bully Naruto!?

"Heh, go ahead and try. Even if I've run out of chakra and have to hold a shuriken in one hand, I, Uchiha Sasuke, am still invincible in this world!"

Sasuke stands with his hands behind his back, radiating sheer coolness.

"Sasuke!!"

Naruto is moved to tears.

"Ding! Congratulations, Host, you successfully showed off. You have obtained the Flame Dragon Armor Summoner!"

Chunin Exam showdown: "Rock Lee? Heh, the Eight Gates? Nothing special! Let me defeat you completely in the field of taijutsu you're most proud of!"

"Ding! Congratulations, Host, you successfully showed off. You have obtained the Three-Tomoe Sharingan!"

"Kaguya... you're a good woman. I understand your good intentions. Let's be together!!"

As long as you're bold enough...
