Disgaea 4: A Promise Unforgotten is a tactical RPG and the fourth installment of the Disgaea series by Nippon Ichi Software. Using turned based combat and the isometric battlefield gameplay from the previous installments, Disgaea 4 includes new features, such as the Magichange system.
The game follows Valvatorez, a vampire who was once feared as a tyrant until he promised a woman 400 years ago he'd not drink blood again until he could instil fear in her. Unfortunately, she died before he could do so. Disgusted by the corruption of the government and tired of his menial job of turning dead humans into Prinnies, Valvatorez, alongside his loyal servant Fenrich, plot a rebellion and battle across the Netherworld to win the support of the masses.
