A Ghost King? Just My Golden Echo!

Wuthering Waves, Demon Slayer, fan fiction, goofy humor, strong female lead, invincible, not a self-sacrificing saint, wild imagination, overwhelming power, lighthearted comedy

In this story, the protagonist can spend cost during battle to switch Echoes, and their cost limit increases as their Echoes gain experience.

The bad news: I transmigrated into Demon Slayer, where demons are everywhere, and I'm about to get eaten from the start!

The good news: I'm a Wuthering Waves player, and I came with an Echo menu!

Ling, a top-tier grinding fanatic, has somehow turned the tragic world of Demon Slayer into an open-world game!

There is no fate here, just a brand-new map covered in “rare materials”!

While Tanjiro weeps for his sister, Ling's eyes light up as she scans her. “Half-human, half-demon? Is this a rare mob that drops a gold Echo?!”

From then on, the Demon Slayer Corps takes a wildly different turn!

While the Hashira train hard in their Breathing Styles, Ling plans out her “farming route.” “Lower Rank Demons are purple four-stars! Upper Rank Demons are gold five-stars! I have to collect the full Twelve Kizuki set!”

She turns a fallen Upper Rank into a +20 Crit Echo! She tears down the Infinity Castle because “the map's too big, and you can't fight the boss without clearing the mobs first”!

Muzan Kibutsuji: “Stay away! You're going to drain all my subordinates!”

Ling: “Don't run! You're the last one I need to complete my perfect Echo set!”
