Got it! A true Saiyan start!

With the system in hand, the world is mine!

Becoming stronger? Super Saiyan? Bulma on the left and Chi-Chi on the right? It's just around the corner!

However...

"Haki is also qi! I've practiced correctly!"

"Although I can transform when I see a full moon, I'm not a fur tribe!"

"What is ONE PIECE? What is One Piece? Where are my Dragon Balls?!"

......

Day 1 of the journey: The Dragon Ball world is too dangerous! Stay safe and develop!

Traveling through time: Huh? It seems just like that?

After traveling through time for N years: What kind of bugs are the Celestial Dragons? This is my Earth!
