A young man addicted to online gaming unexpectedly transmigrates to the Demon Slayer world. Before he can even figure out what's going on, he's bonded with the alien symbiote Venom, and through a series of mishaps becomes the Demon Slayer Corps' most absurd “Iron Pillar.”
He doesn't know a Breathing Style, but the symbiote lets him withstand Upper Rank demons' Blood Demon Arts. His arm gets torn off? The next second, tendrils wrap around the severed limb and reattach it, healing so fast even demons stare in disbelief. A demon's claws punch through his chest? Black liquid surges from the wound and fills it in an instant, then he bites his opponent's fangs to pieces.
When Water Hashira Giyu gives him a wary look, he pats the symbiote on his chest and laughs. “You can sharpen your sword all you like, but you can't heal faster than I can.” In the middle of Flame Hashira Kyojuro's fight, he turns around to find the young man crushing a demon's head with his bare hands, black goo dripping with blood. “Sorry, I stole your prey.”
As if it weren't enough for this transmigrator to have a cheat, his cheat is tougher and hits harder than demons do. The demons are utterly baffled: What kind of monster is this? He's more demonic than we are!
The subject matter is novel, but as a fan, there is a low-level conflict-level OOC. At the same time, Venom's ability is expressed like a biological prosthetic rather than a symbiote.
I came here after seeing this video on Douyin and thought it would be very interesting.
Too much OOC, although it's quite cool
