Demon Slayer: Muzan, Times Have Changed

Roger transmigrates to the anime world of Demon Slayer and obtains the Power of the Sun System.

Sun Breathing merely borrows the sun's energy, while I use the sun's power itself.

Demon slayer swordsmen? Hand-to-hand combat? That's already outdated.

Take a look at this Gatling gun before you talk! How are you going to withstand bullets infused with the power of the sun?

What Blood Demon Art? What Upper Rank Demons? What Muzan!

In front of my great equalizer cannon, you're all small fry.

Akaza: You can pierce my Destructive Death technique? Just who are you?

Muzan: Even Yoriichi Tsugikuni never drove me to such lengths. Are you the sun itself?!

Shinobu Kocho: Thanks to you, I was able to get my revenge. Little Roger, how would you like me to thank you?

Kanroji: Roger, I heard you're treating me to dinner again? What do you mean, only at night...

Master: Roger, you can take over as Master!
