Reincarnated as the Piggy Duke: This Time I’m Gonna Tell Her How I Feel! Volume 4 by Rhythm Aida

Slowe is invited to the royal castle to receive his reward for slaying the dragon. There, he hears a shocking report: Rooney, a soldier of the Dustour Empire, has appeared in Huzak...which marks the start of the storyline from the first twelve episodes of Shuya Marionette! Rooney tries to start a war with the south using the monster-controlled Huzak as a foothold. Slowe then transforms into an orc and infiltrates Huzak to stop him!

However...

“Why do I have to wear this?!” He ends up having a big quarrel with Charlotte, who transforms into a pixie!!!

And then...

“As a token of our thanks, we'll make a bronze monument of you in this village! Oink!” The orc village that Slowe visits begin to wholeheartedly worship him as a hero!

Can the Piggy Duke successfully prevent his new life from playing out like the anime?
