Dokuganryuu Masamune

Profile
Present Youkai king. He is very similar to Rance in his laid-back and self-centered lifestyle and even has a harem of 4 wives: Omachi, Noir, Orime and Nogiku. He's probably the only person in Japan who owns a car (a toy car, but still) and even uses it in battle. Rance defeats him by making him not use his eye drops.
