Kunoichi

The Kunoichi is a recurring humanoid class in the Disgaea series first introduced in Disgaea 2: Cursed Memories.

Characteristics
Kunoichis are beautiful assassins with murderous intent, who use their looks to seduce their targets. Kunoichi are not as strong as Ninjas, but make up for it with unrivaled speed, comparable to a black panther. Kunoichis are also very loyal and often serve as guards to royalty. Kunoichis secretly admire cute clothing, in part due to being forced to wear a plain uniform.

Disgaea 2: Cursed Memories
The Kunoichi is unlocked by having a unit with level 5 Fist and Staff mastery. Their special ability grants them a 50% chance to have an extra attack while their HP is critical.

Disgaea 3: Absence of Justice
Kunoichi are unlocked by having both a level 30 Fight Mistress and Mage. The Kunoichi's primary Evility, "Flame Haze" allows them to have a 50% evasion rate when dodging skills that hit multiple spaces.

Disgaea 4: A Promise Unforgotten
The Kunoichi is a downloadable class in Disgaea 4. They are unlocked by purchasing the Kyoko and Asuka DLC pack and defeating them on the DLC fight. They are similar to their Disgaea 3 counterparts, retaining the "Flame Haze" Evility and Weapon Forte. They can learn secondary Evilities that can boost their damage output such as increasing critical hit damage by 100% or attack power if attacking enemies multiple times.

Disgaea 5: Alliance of Vengeance
The Kunoichi returns in Disgaea 5, again as a DLC class.

Trivia

 * The Kunoichi's recurring initial Evility, "Flame Haze", is a prospective reference to light novel, manga and anime series, Shakugan no Shana.   Flame Haze are humans chosen by lords of the Crimson Realm in order to fight Crimson Denizens who have leaked into our world in order to feast on humans' Power of Existence (quintessence) for varying motives and reasons.
