One Piece: Awakening the Spatial Fruit, I Save Zephyr's Wife and Child

Transmigrated as Zephyr's son, Zeyu starts out at age three with a System space: the Spring of Life, a Substitute Death Jade, and the Dragon Spring Sword, the whole set is ready to go. His father brings back two Devil Fruits, the Logia Hurricane Fruit and an unknown silver-white fruit. Betting his life, Zeyu swallows the silver-white fruit: the Paramecia Space-Space Fruit is his! He awakens three abilities, Space Ripples, Teleportation, and Space Slash, then promptly exhausts himself into a coma. Zephyr blows his top on the spot: "You little brat, you ate that one?!" He turns around and hands the Hurricane Fruit to Dragon. Dragon takes one bite and summons a storm of wind and thunder right there, his eyes welling with tears. "Brother, I'll remember this life debt forever."

Zephyr sails out to suppress Whitebeard, and enemies storm the family home. Zeyu's Space Slash holds off a commodore-level pirate, while the Substitute Death Jade protects the mother and child as their lives hang by a thread. Dragon descends from the sky on a hurricane, his Conqueror's Haki shattering half the roof. He grabs Pasley's throat and snarls, "You laid a hand on my brother?!" Ace and Luffy haven't even been born yet, but Zeyu is already grinning on his sickbed:

"Big Brother Dragon, your son will have to call me Uncle someday."
