Buta no Liver wa Kanetsu Shiro

A run-of-the-mill otaku collapses from stomach pain after tasting 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, comes along and 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 Jess's side, it seems like life as a hog might not be so bad after all, yet there's more to this strange fantasy world than meets the eye. Jess is a girl of many secrets, and she's in danger. But what can a mere pig with no special powers do to protect her from her cruel fate? Will his modern knowledge, quick thinking, and sharp nose be enough to ham it up and save her?(Source: J-Novel Club)
