(Mythical Zoan + Zanpakuto + talisman talent + semi-invincible protagonist + master swordsman)
The System's starting reward is the Torch Dragon Fruit and the Zanpakuto Wei Tian Minghong.
After transmigrating, he imagines he'll be just like Luffy, punching Admirals and kicking the Four Emperors, then loudly proclaiming to the whole world, "I don't eat beef!" Instead, Garp punches him back to reality, and he discovers he's Luffy's uncle. Luffy is still just a bundle of cells, so all he can say is that the First Emperor hadn't even started his enterprise before he went off to join the army.
Later, he saves Zephyr's wife and child, torments Akainu, and tears into Kizaru.
"So you're Shanks, huh? You're the one who tricked my nephew into becoming a pirate, right? Let's see if I can't trick you into joining the Marines instead. I don't care whose face you think you can save, damn it!"
Momonosuke: "What did I do wrong?"
"Want to live? I'll bet you that the beef noodles your sister cooked have scallions in them, because I just insulted your father."
When the noodles are served...
"I don't eat beef!"
A flash of blade, and a blood-soaked head soared into the air!
(The System is just there for flavor. Aside from the two starter packs, everything else is just comic relief.)
I'll give it four stars. I feel that the evaluation of those three knives is a bit too high.
