I Am Luffy: Partner System Online (One Piece)

After dying in his sleep, a modern-day anime fan isekai as a child, crewless Monkey D. Luffy. No crew. No Haki. No Gum-Gum fruit… yet. Just pain, awkward child limbs, and a system that turns life into a grindfest. Then the Partner System kicks in. To grow stronger, Luffy has to power up others first, because apparently being the main character wasn’t hard enough. Each buffed-up partner boosts his own stats and unlocks powers from across the anime multiverse. Fairy Tail magic? A one-hit kill blade? A soul-cutting sword that speaks? Absolutely. Now armed with grindable friendship, hellish Garp training, and a suspiciously game-like UI, Luffy’s ready to recruit his way to Pirate King. A dark, reimagined One Piece universe. — Description from novelcodex.orgFull novel: I Am Luffy: Partner System Online (One Piece) — read the rest free on N​o⁠v​e⁠l​C⁠o​d⁠e​x⁠.​o⁠r​g⁠
