“The human representative of NIS. A heroine of justice. Don't mention her flat chest to her.”
Heroine is Nisa's exclusive class in Disgaea 5: Alliance of Vengeance. Her unique evility is Nippon Ichi, which raises her stats by 1% per ten hours of total game time. It should be noted that should the player reach one thousand hours (100% stat increase limit), any other potential stat-increasing effects will be ineffective.
