Demon Slayer: Sukuna's Template from the Start, Muzan Is Scared Senseless

Tomioka Yaba transmigrates to the Taisho era and witnesses his family slaughtered by demons.

Just as a demon opens its gaping maw, the [Supreme Villain Template Roleplaying System] activates! From the start, it loads the template of the “King of Curses,” Ryomen Sukuna!

“You call that a demon? It’s nothing but a lowly piece of trash.”

A slight movement of his fingers sends invisible slashes ripping the demon into countless chunks of flesh! His attacks carry soul curses, rendering the demon’s vaunted regenerative powers useless!

After he joins the Demon Slayer Corps, the whole story takes a drastic turn.

When he encounters Akaza, Upper Rank Three, Akaza laughs wildly. “Your fighting spirit is strong. Become a demon!”

Yaba grins madly as strange black markings appear across his face. “You’re too weak. Trash like you isn’t even worthy of giving me pleasure. Domain Expansion: Malevolent Shrine!”

That night, invisible slashes reduce the entire mountain, Akaza and all, to a cloud of dust.

Inside the Infinity Castle, Muzan Kibutsuji watches the images sent through Nakime’s eyes. His whole body trembles, and he hardly dares to breathe aloud.

“Who is it? Who unleashed this monster?”

[A slow-paced story. I’ve been having a rough time lately watching Demon Slayer, so I’m starting this to make up for some of the regrets.]
