Anime Crossover: Learning Zenitsu's Thunder Breathing from Demon Slayer

Fang Hao transmigrates into a high-risk world where anime universes overlap. From the start, he binds himself to a Legendary Codex. Though he's a frail, unhealthy good-for-nothing, he unexpectedly awakens a heaven-defying talent for swordsmanship, learning anything at a glance and applying what he learns to everything!

He accidentally stumbles into the Taisho era of Demon Slayer, facing a desperate world overrun by demons and ravaged by Blood Demon Arts. By chance, he reaches the summit of Mount Sagiri and becomes the pupil of former Thunder Hashira Kuwajima Jigoro, where he meets his fellow student Agatsuma Zenitsu. From then on, he sets out on a heaven-defying path of Thunder Breathing.

While others toil for years without grasping the basics, he masters the essence of Thunder Breathing with nothing but a wooden stick. He not only perfectly replicates First Form: Thunderclap and Flash, but also masters all six forms and independently improves the breathing technique, reducing its drawbacks and boosting its stamina. He amazes the entire Demon Slayer Corps!

During the final selection on Mount Fujikasane, he kills a demon with a single slash and stands against the monstrous Hand Demon. Together with Kamado Tanjiro, he sweeps through the deadly trials. From grueling training on Mount Sagiri to the front lines of the demon-slaying war, he uses his lightning blade to vanquish evil and his incredible speed to command the battlefield. He breaks free from the chains of fate, protects Zenitsu, and delivers face-slapping comeuppance to his enemies. He will even cross into other anime worlds and rise to the pinnacle of combat, becoming a Thunder Swordsman feared throughout the Myriad Worlds!
