Wang Rong transmigrates into Demon Slayer, and gets an Ultraman Badge and fuses with Taro from the start.
The Transparent World, Demon Slayer Marks, Ultra Psychokinesis, and several tons of strength: is that really too much?
Wang Rong says nothing, simply unleashing a beam of light at Hantengu.
And so, a living powerhouse who treats demons like a casual mobile game appears.
In Infinity Castle, Muzan trembles: “I’m fighting Taro? Seriously?”
Upper Rank One, Kokushibo: “I opened all six eyes too soon. I haven’t seen Wang Rong open his eyes with a single basic attack in hundreds of years.”
Wang Rong: “My big brother Taro got tired of fighting Grand King, so he came to Demon Slayer to relax. Demon King? Upper Ranks? I thought you were just speed bumps for an Ultraman.”
(The protagonist arrives with Taro’s consciousness, has an Ultraman-level physique, is invincible, loves a good laugh, and is extremely dedicated to slaying demons.)
Depending on how things go, the story may continue in the Ultraman universe or move on to other crossover worlds. I’m a beginner writing for fun, so everyone’s welcome. Just don’t think too hard while reading!
