Butareba -The Story of a Man Turned into a Pig- Sixth Bite

After finally vanquishing the most atrocious mage, Mister Pig and his companions have reclaimed the royal capital. Now, it’s time to head to their happy ending—but unfortunately, rebuilding a country from the brink of ruin isn’t quite that simple. They have plenty of problems on their plates, including but not limited to: dealing with the chaos caused by the two merging worlds, restoring the royal court that was pushed to the edge of collapse, and tackling the cruel Yethma system. Having found a hint leading to a special artifact that’s key to the Yethma’s liberation, Mister Pig and Jess prepare to begin their search—but an uncanny and enigmatic series of murders stand in their way. Under the request of the new king, Shravis, the pair launch an investigation to unravel the case...but are they ready to face the monster called truth?
