Rozalin

Rozalin is the heroine of Disgaea 2: Cursed Memories and Disgaea 2: Dark Hero Days.

Story
Rozalin is the daughter of Overlord Zenon, although she has lived most of her life sequestered in a massive mansion surrounded by servants and given everything she could have ever wanted. One such servant is Tink, who later gets turned into a frog. Mom attempts to summon Overlord Zenon, but instead summons her and ends up binding her to Adell. Being stuck with Adell, she attempts to rid herself of him by secretly planning to kill him. Her attempts however always end in failure due to Adell overcoming the trap or the trap turning on Rozalin, forcing Adell to save her. Due to being locked up inside her mansion, Rozalin not only doesn't know how to fight properly but she also doesn't know where her mansion was actually located. She is also inexperienced in the ways of the outside world, relying only on what she learned in text books from her Mansion's library. She also often announces to people that she is "Overlord Zenon's One and Only Daughter" while flashing the Four Leaf Clover mark she has, claiming it to be a symbol of the bond she has with her father. After the battle with Demon Lord Etna it is revealed that Rozalin doesn't even know where Overlord Zenon is nor what he even looks like. Over the course of the story, Rozalin grows more as a person and learns to like Taro, Hanako and even Adell. During the Tournament Arc, it is shown that she is unsure of what to do if the group wins the tournament and is granted the chance to see Zenon due to her experiences in the outside world. It also revealed that she is in fact a closet Prism Rangers fan. When the group goes to Shinra Tower to get herbs to help Fubuki (with Etna wanting to find something to fix her loss of levels), they come across Laharl who not only annihilates them in a fight but also smashes Rozalin's Four Leaf Clover mark which is soon revealed to be a seal holding back the soul of the true Zenon. Laharl, surprised by Rozalin's increase in power, is defeated so he decides to take his leave and come back for Etna later. Rozalin is unable to control Zenon's soul until Adell snaps her out of it (by slapping her). During the Final Battle with the False Zenon, the real Zenon tells Rozalin to shatter the seal again if she wishes to help her friends. She does so and the real Zenon destroys the impostor with a single blast. In the good ending Rozalin soon aims her wrath at her friends only for Adell to snap her out if it with a kiss (causing her to go ballistic and chase him as shown in the credits). In the worst ending, Adell fights and kills her, only for the soul of the real Zenon to posses him.
