Anime Crossover: I Rework Thunder Breathing from the Start, and Zenitsu Becomes My Disciple

Fang Hao transmigrates into a world of crossover anime and binds himself to the Legendary Chronicle, which lets him forge abilities by writing his own epic feats and travel across the Myriad Worlds. His first stop is the world of Demon Slayer, where the System grants him Swordsmanship Prodigy A. He can come up with sword techniques using nothing but a random stick. He squats down by the roadside and starts swinging it around, frightening passersby into taking a detour.

He climbs the mountain to become Jigoro Kuwajima's disciple. After a year of training at Mount Sagiri, he masters all six forms of Thunder Breathing and even refines them, halving the stamina cost without reducing their power. His junior disciple, Zenitsu Agatsuma, clings to his leg and sobs. "Boss, you're the best!" Fang Hao answers with a shoulder throw, sending him into a mud pit. "Quit talking and practice your draw."

During the Final Selection on Mount Fujikasane, Fang Hao keeps monsters busy with one hand and fishes with the other. He dispatches minor demons with a single slash, sheathing his sword faster than their corpses can turn to ash. When the Hand Demon appears, Tanjiro is in a furious rampage. Fang Hao strolls out of the shadows, flashes with lightning, and cuts off the giant arm swinging at the boy. He gives Tanjiro a slight nod:

"Don't rush to get yourself killed. Let's take him on together and tear him apart."
