The modern social animal Lin Ye traveled through Naruto with the power of the Shinigami. He thought he could be cool with his Zanpakutō, but he discovered that his first ability was to "make everything it touches slippery."
When he hit the ground and broke into Naruto to steal ramen, he used a knife to "slip" away the pursuers, and was mistaken by Kakashi for the "Special Blood Step Family"; he joined the Konoha extra-staff team and used "slippery" to help Naruto hide in training, but Sasuke fell into the mud pit; he faced Gaara in the Chunin Exam and turned the sand escape into a "quicksand slide", forcing Shukaku to tremble with laughter in the gourd.
What's even more outrageous is his swastika solution - turning surrounding objects into trampolines. When trying his hand, he turned the Hokage Rock into a trampoline, causing all the Hokage statues to collectively "bouncing New Year greetings"; when he met Deidara, he used a trampoline to bounce the C4 bomb back, making the other party yell "This is not a ninjutsu, it's magic"; even Pain's Shinra Tensei was bounced into a "Moon Express".
When the Shinigami's spiritual power collides with the ninja's chakra, when Kidou is recited as a "lighter spell", when Aizen's "Do you desire power" is replied with "I crave barbecue" - Lin Ye just wants to say: in the world of Naruto, doing the Shinigami business is the most reliable way to be funny.
This is a funny story about using slippery abilities to disrupt the ninja world, causing the Akatsuki organization to collapse, leaving Naruto scratching his head, and making the strong men of both dimensions collectively confused. After all, who would have thought that the key to ending the great ninja war would be "how to make Kaguya stand without slipping"?
