Lambda -No.11- is an imitation Murakumo Unit found, experimented on and controlled by Kokonoe Mercury. She replaces Nu-13 in Continuum Shift and returns as a standalone character in Chronophantasma Extend.

She was voiced by Kanako Kondo in the Japanese version, and by Cristina Valenzuela in the English version.


Lambda is an imitation Murakumo Unit created by Relius Clover and then controlled by Kokonoe with combing the body of the 11th experimental replica of Saya with the soul of Nu-13, recovered after falling into the Sheol Gate during the conclusion of Calamity Trigger's Story Mode.

Continuum Shift

She was originally mentioned in the opening of Calamity Trigger's Story Mode. She becomes a member of Sector Seven with Kokonoe and Iron Tager after being fully restored, and is originally sent to provide backup for Tager.


In her arcade mode, Lambda lost all of her memories including her name and Ragna. Rachel and Noel decide to test her strength by pitting her against several simulated opponents culminating in a match against an illusion of Nu-13. She finally defeats Nu and remembers her name and Ragna.


Lambda greatly resembles her predecessor Nu, but with the exception of a palette swap; having light blond hair, a tan complexion, and black and white armor. From Chronophantasma onwards, Lambda has a constant dark green aura enveloping her.

Within her battle armor, she is identical to Nu, save for the key differences above. Her actual appearance is that of a young woman with tanned skin and long, light blond hair that is tied into an plat that easily reaches the back of her calves. She wears a huge visor with a single red eye, the visor has two massive ear-like constructs coming out of its sides that skim past the back of her head. Lambda typically wears a black body tight jumpstart that covers her from her neck to her upper thighs, the suit has no back and has a small metallic piece covering the bottom center of the pelvis. When in her

Outside of her battle form, Lambda wears her black jumpsuit ans a cape that divided into three cloves. The cape itself is black, white and yellow, the lower parts of the side cloves have inscribed on them the letter, signifying her status as Murakumo Unit. Her cloak is held together with a large metal tablet which has her crest engraved upon it; hanging from this tablet is a yellow and white fabric.


At the beginning of her story in Continuum Shift which showed her past where she was in the middle of being experimented by scientists, Lambda was full of emotion and seemed to act slightly similar to Noel in some aspects. However, because her desperate pleas for help could not be heard, and because the scientists had taken experiment on her to the extreme, Lambda had unfortunately died from the experiment.

In Alter Memory, Lambda was first shown to be an emotionless weapon following Kokonoe's orders, but later it was shown that Lambda was an innocent girl at heart who didn't know anything. She was shown to be caring towards an injured Tartar that Arakune had dropped and was sad about its death. Because she never had experience in the outside world, she had tried to copy what Ragna does after seeing him, from trying to find medical herb inside patches of grass, except hers was made badly. She also did not know the meaning of being "gentle" at the time, where Ragna had taught the meaning behind it.

Powers and Abilities

Lambda's powers are similar to Nu's, difference being that hers are significantly weaker in comparsion, with slower swords being summoned at a closer range. She also has a much larger emphasis on guard breaking compared to her predecessor, and more close range options. It should be noted that she is seemingly weaker than Nu as she doesn't possess the ability to revive herself from near death. As well as this, she doesn't seem to be as powerful as Nu because of her ability to take out an illusion of Mu -No.12-, compared to Lambda being wiped out by Mu in her Arcade Ending. Adding to her list of weaknesses, Lambda's armor is made out of titanium and light metals as opposed to Nu and Noel's components of 'hihirokane'; meaning that she can take much less hits as opposed to the aforementioned two.


Lambda is the eleventh number in the Greek Alphabet and is the first part of Lambda's Murakumo serial number. The second half of her serial number is 11 which serves to represent her status as the eleventh Murakumo Unit created.

Unlike her fellow Murakumo Units, Lambda's name has no relation to death.



  • During combos with her swords, she will count up the hits in German, for example "Zwei, Drei, Vier, Funf, Sechs, Siben, Acht". Her voice files include numbers in German up to 20.
  • During the events of Continuum Shift, Lambda's restoration was incomplete, only about 90% of her was functioning.
  • In​ Continuum Shift, Lambda's does not have her own true unlimited form. Instead, she is replaced by Unlimited Nu when selected.
  • If her Unlimited form is selected, Lambda will not count up hits with her swords in German (as Nu did not do this in Calamity Trigger), and all lines against certain characters wll be replaced with generic lines. However, in English dub, Nu will still refer to herself as Lambda -No.11-.
    • However, as Chronophantasma, Nu starts counting up her hits in German in a similar grace and manner to Lambda.
