Code Title: Bonus Boss Battle
After completing the Gate Generator and having Rudy rejoin the party, go to Saint Centaur and talk to the blind girl in the building under the Lone Paula Statue. The blind girl will tell you about a swordsman who had been frequently visiting her during the past few days. After this, leave the city and a message will notify you of a strange laughter. When it says "Do you wish to Continue?", choose yes. After a little cutscene, you'll be in a bonus boss fight againts "Monster Zed".
