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

A run-of-the-mill otaku collapses from stomach pain after eating raw pig liver and wakes up in a whole new world—as a pig, of all things! He’s helplessly trapped in his pen until Jess, a girl who can read minds, rescues him. Our porcine hero will have to work to keep his boar-ish thoughts to himself. But sweet Jess isn’t deterred. In fact, she wants to spoil this little piggy rotten! By her side, it seems like life as a hog might not be so bad after all! For our pig protagonist to transform back into a human, he must head to the capital and appeal to the king. Jess offers to go with him, kicking off the start of their cutesy, fluffy adventure! But while preparing for their journey, what seems like a harmless shopping trip quickly gets out of hand, revealing the dark side of this world hidden beneath its peaceful facade. What can a mere pig with no special powers do to protect his angelic savior?
