"I will be as cool as Etna, but twice as sexier!"

Help Nisa grow up quickly by expanding this article into a full one, and maybe it can one day be sexier than Etna. Try asking for details on its talk page.

“Stop saying I'm flat!”
—Nisa, Disgaea 4: A Promise Unforgotten

Nisa is a character from the Hyperdimension Neptunia series. She is one of the two downloadable playable characters. She is a self proclaimed "hero of justice" filled with passion and bravery. Nisa takes great offense to comments about her chest.

Like several other Neptunia characters, she is an embodiment of a game company, in this case Nippon Ichi Software. Nippon Ichi was her Japanese name since it's supposed to represent Nippon Ichi Software. NISA is the American branch (Nippon Ichi Software America), thus they chose to call her Nisa for the U.S. release of Neptunia.

Due to the internal strife between Nippon Ichi Software and Compile Heart, both cut ties to each other, including NIS America, which resulted to Nisa being seperated from her series origin.


Nisa has medium length bright dark blue hair and eyes, accompanied by a pair of black goggles with yellow-orange lenses. She wears a black shorts-jumpsuit that is zipped all the way down along with a red scarf tied around her neck and a prinny backpack. She wears gray gloves with white cuffs and black buttons along with matching shoes.


Nisa has a generally upbeat and optimistic persona. She is kind and selfless; always putting the safety of others, and most importantly any world that she lives in, before anything else. She believes that good will always triumph over evil and has an extremely strong sense of justice. Nisa is also very insecure about her ironing board of a chest which can cause her to become very violent and less righteous when made fun of about it to the point that she lets go of her morals just to attack anyone that mentions or makes fun of her flat chest.


Gameplay wise, she has two unique evilities. The first is called "Nippon Ichi", which makes her stats 1% stronger for every ten hours of game time on the player's save file. The second is "Flat Alliance", which boosts the stats of all flat-chested characters on the field by 10%. Her special attacks include "Zettai Hero Legend", "Dark X Slash" and "N I S A".


Disgaea 4: A Promise UnforgottenEdit

Nisa is a DLC character for Disgaea 4: A Promise Unforgotten. In her demo, she introduces herself and jumps into the room, proclaiming herself as the Heroine of Justice who has come to save Vulcanus and Fuka from the demons. Both Vulcanus and Fuka are initially confused until Emizel remarks about her flat chest. This causes Desco and Fuka to also take notice of this as well. Nisa then becomes angry, and challenges the party without waiting for Valvatorez's explanation.

After being promptly defeated, she proclaims that she will battle them again, but Valvatorez finally calms her down by telling her why Vulcanus and Fuka are with them. Quickly understanding, she explains herself that she was invited to the Netherworld as a Heroine of Justice. Valvatorez takes a liking to her and invites her to the party. Fenrich then surprises the group by happily accepting her and stating that he was the one who sent the invitation. Nisa then decides to help the demons protect the peace of the Netherworld, no matter how ironic it sounds.

Disgaea D2: A Brighter DarknessEdit

In Disgaea D2: A Brighter Darkness, Nisa appears as a DLC character.  In this game, her Evilty increases her stats by 5% per "flat" unit in the party.  This includes characters still in the base panel.

In her scenario, she is one of the contestant of an event, with her rival being Etna. After their introductions, Etna asks Laharl and his group to help her defeat Nisa, despite the boy's annoyance.

After the battle, Nisa declares that she wouldn't give up but was taunted by Etna, who taught that she won the "Cutest Girl in the Netherworld Contest". Nisa disputes her claim by saying that the contest is actually "Ultimate Heroine of Justice Contest", which is why she is determined to win. The group was confused until Sicily asks the host about the contest, in which the host replied by saying that it is the "Flat Chest Contest", which shocked and angered the two girls, leading to them to punch away the host unclaiming their flatness.

Disgaea 5: Alliance of VengeanceEdit

In Disgaea 5: Alliance of Vengeance, Nisa appears as a DLC character. The Evilty she starts out with in this game is "Nippon Ichi", which makes her stats 1% stronger for every ten hours of game time on the player's save file. Her other Evilities are "Dangerous Revival", which increases her stats by the % of HP healed, and "Belated Hero", an Evility that increases her stats if she becomes the last unit of a force. She also has different skills in this game. Her skills are "Justice Knife" as her starting skill, "V Extreme" as her next one, and then "N I S A" as the last one. She has an "S" aptitude in guns and swords and has a movement of 7.



  • Despite being voiced by the same voice actress, Nisa has a deeper voice in the Disgaea series compared to the Neptunia series.
  • Despite the seperation of both Nippon Ichi Software and Compile Heart due to bad terms, Nisa can be heard mentioning "Gamindustri", the world where the Neptunia series happens, in English dubs, which might indicate that the international branches, NIS America and Idea Factory International, are not affected by the strife.
  • There is a possible connection between the main Neptunia series and Disgaea 4 as one of Nisa's Chirper event in Hyperdimension Neptunia mk2, she recieves an offer to "save Netherworld from evil" before leaving the group for a few months to work out. In Disgaea 4, a similar explanation was given by Nisa in her scenario before Fenrich reveals himself to be the one who sent the offer.
