One Piece: I Have a Supreme Great Grade Sword, and I Show Off with Red-Hair

Li Bu transmigrates to the world of One Piece and becomes Griffin, a supreme-grade Great Grade Sword. From the start, he activates the Emperor's Great Sword System.

From the start, he runs into Shanks at an auction. At this point, Shanks is still a humble, refined young pirate, and he still has both arms.

If Shanks doesn't learn to show off, won't Luffy die in the Summit War someday? Won't Kid keep tormenting civilians? Then what's the point of watching One Piece?

I'm joining the Red-Hair Pirates. I'll teach Shanks to show off, and bring every beauty and Great Grade Sword into my harem.

Luffy, I hear you want to become the Pirate King? How can you be the Pirate King without the hat? Watch me coach Shanks into losing an arm and giving you the hat.

Ace, I hear you're the strongest weapon? Griffin won't stand for that.

Akainu, you dare touch my blade with your fist? Do you want to lose that hand?

Mihawk, your weapon is beautiful. She's my sword now.

I hear there are twelve supreme-grade Great Grade Swords? I'll collect them all as my underlings. I'll become the Emperor of Swords...
