Nagi su Ragarl

Profile
She is one of Zeth Four Heavenly Kings.

Her father is Chenezale do Ragarl.

(Updating in progress)

She didn't have a normal childhood, the only things she had in her life were the study of magic and her father.

She holds a grudge against her half sister, Masou Shizuka, believing that it is unfair that only her sister knows happiness, while she has known nothing but unhappiness. This grudge has driven her half mad and she has made magical enhancements to her body in order to defeat her half sister, which have made her a half monster.

Like her sister she doesn't surrender easily and her vengance is all she can think about.

In one special ending in Rance 9, she and Shizuka have become children again and are trying to make up for the time both of them lost.

This Nagi is full of energy and is always jumping, smiling and playing around. She doesn't hold any memories of what she did before, or at least she claims not to.

Rance 2
She only appears in Rance 2 Box Art.

Rance 6
She is one of the Four Heavenly Kings, guardians of the Mana batteries that keep running the Magic Line. Nagi is the only one of the four that is able to protect her Mana battery from the attacks of Pentagon.

Later in the game she presents herself as Masou Shizuka 's little sister and daugther of Chenezale do Ragarl.

Later, she is defeated and raped (but not killed) by Rance.

Post Rance 6, Nagi crosses the border into the realm of dark lords to acquire greater power to overpower Shizuka. In her quest, she's attacked by a group of monsters, falls from a cliff and loses her memories. She is afterwards rescued by dark lord Kesselring, who recruits her as an apprentice maid. Soon impressed by her capabilities as a maid, Kesserlink nearly turns her into one of his apostle maids. However, right before that happens, Nagi regains her memories and barely manages to escape demon realm.

Sengoku Rance
She only appears in Uruza Talk Event when Uruza decided to go JAPAN.

She is also mentioned by Maria when she arrives as a reinforcement. She has tried to kill Shizuka 4 times already, and that's applied to Maria as well.

Post Rance Quest
Nagi survives a massive attack by a ferocious monster on the city she was in and wakes up in a hospital. She immediately slips out of hospital even in her injured state, and pursues Shizuka. However, upon finding Shizuka, Shizuka has no intention to kill her and simply states "kill me if that's what satisfies you". As Nagi feels that she would not feel any satisfaction from just killing Shizuka like that, she decides to first instigate hatred in her towards herself the same way she hates Shizuka - to accomplish this, she now targets Shizuka's best friend Maria Custard instead.

Rance IX

During the events in Hellman, Nagi tries to kill Shizuka several times. She's added some monster parts to her body, which have enhanced her magic powers, but are killing her slowly in return. Besides she seems to lose control from time to time and seeks sexual release, losing all her memories from those events after she's regained control of her body. Her mental state has deteriorated considerably. She speaks alone and is more aggressive than ever before.

In one special ending in this game, Nagi is finally succumbs to her wounds and is about to die, but Shizuka decides to share with her, her life, body and happiness turning them both into small children. This new nagi is playful and energic, and has no memory of what she did to her sister before. All other characters refer to those events as "causing her sister some troubles". She loves her sister very much and always wants to be with her. She also seems to like Rance a lot as well, but it is not explained why that is.

Rance manages to return both of them to her older selves with an item found in the treasure chamber of the Hellman castle, the "Banjo rope", and the three of them live together in Rance's castle.
