Buta no Fukushuu

“All my classmates must die!”

The man had been bullied all his life, for just one reason: His face looked like a pig. While the despair grew day by day, he found himself transported to another world where he made a happy life. But that life was torn apart by his classmates, who were also transported to that world... Done with taking the abuse, the man begins his revenge.
