Lin Feng transmigrates into the world of Demon Slayer.
And of all people, he ends up as the “biggest coward of all,” Zenitsu Agatsuma!
From the start, he's at the Mount Fujikasane selection, surrounded by man-eating demons.
His legs turn to jelly, and he clings to a tree, swearing all he wants is to survive.
“Ding! The God-Tier Survival System has activated!”
“Host's ultimate instinct to avoid danger detected. Reward: Thunder Breathing: Thunderclap and Flash, max level!”
“Successfully clung to Tanjiro once. Reward: Armament Haki!”
“Trembling behind Nezuko's box. Reward: super-speed regeneration!”
From then on, the Demon Slayer Corps gains a swordsman whose style is completely ridiculous.
When conscious: “Stay back! I want to go home and get married!”
When scared unconscious: “Thunder Breathing: Thunder God Descends!”
During the final battle, Muzan watches the “good-for-nothing” blond blow the Infinity Castle to rubble with lightning and completely loses it.
“Can someone tell me why this guy, who keeps screaming for help, just wiped out all the Twelve Kizuki with one strike?!”
