In Demon Slayer, I Just Became the Big Brother. Call the Government!

Lin Yan transmigrates into Demon Slayer and finds himself on the Mugen Train from the start, only to be run through the chest by Upper Rank Three! At death’s door, he binds to the [Salvation Coordinates System] and immediately calls the modern Chinese government!

He is horrified to discover that money from his original world is useless, and that [Radiance Points] are the only currency that matters! Slaying demons and saving lives can earn vast amounts of Radiance Points for China, helping it overcome a nationwide crisis of decline!

[You called the government. Modern China rushed to your aid, and powerful searchlights drove Upper Rank Three back. You gained a vast amount of Radiance Points!]

[You introduced modern technology. Drones tracked Daki and Gyutaro, and a special forces sniper team provided support. Flame Breathing paired with high-explosive rounds to slay Upper Rank Six!]

[You combined modern metallurgy with Breathing Styles, greatly improving the quality of Nichirin Blades. Breathing Style 2.0 empowers the Demon Slayer Corps, making Upper Rank Demons impossible to hide from under the overwhelming advantage of superior technology!]

[You used Radiance Points to strengthen your body. Flame Breathing evolved into “Solar Crown Breath,” making you the pinnacle of both technology and swordsmanship!]

Faced with power beyond his era, Muzan Kibutsuji is gripped by unprecedented terror! The Demon Slayer Corps’ Hashira are overwhelmed by the shock of divine reinforcements from the skies and bow to your command! Thanks to you, the people of modern China become stronger than ever, and even the first signs of superhuman abilities emerge. They hail you as their savior!

From a Flame Hashira on the brink of death to the savior of two worlds, Lin Yan will unite the power of both worlds, uncover the cosmic truth behind demons and Radiance Points, destroy Muzan once and for all, and usher in a new era for humanity!
