Yu Zhu transmigrates into Naruto and, from the start, runs into Hinata being bullied. Reborn as Naruto, the dead-last, he happens to spot a pile of dog poop on the ground, with a line of text floating above it:
[Devil Fruit (Rubber-Rubber Fruit, Modified): A genuine Rubber-Rubber Fruit. Eat it and you'll become a landlubber who can drown in a public swimming pool.]
“Hey, look! Hahaha! Naruto was so scared he ate poop!”
“Wait, that can't be right. Why can his arm stretch so far?”
“Damn it, why can he deflect attacks too? That's terrifying! Is this really the same dead-last Naruto!?”
Getting stronger always means giving something up. Yu Zhu wiped his mouth.
In Hinata's misty eyes, a glimmer of hope appeared.
“Naruto, you're amazing...”
From then on, the villagers of Konoha often saw the white-eyed girl following Naruto, the Nine-Tailed Fox.
Then, one night, a knock came from outside Yu Zhu's house:
“Naruto, I heard there's a kitten at your place that can do backflips...”
Scanning Make-Out Paradise: [Water Breathing: They say anyone who learns this breathing style is incredibly gentle.]
Scanning Susanoo: [Big Luck: We're all doing our best to survive. Ha, I thought it was a speed bump.]
Scanning a dog by the village: [White Zetsu: One of the 10 billion White Zetsu in the army from the Magic Cube.]
When Yu Zhu used breathing techniques, wielded a Zanpakuto, cast jujutsu, and even summoned a Stand to maintain his Pokemon Master Ball, the entire Otsutsuki clan went nuts.
