Short Stories

Trust You

λ-No.11-, commonly abbreviated as Lambda-11 is an imitation Murakumo Unit and Boundary Interface Prime Field Device with Saya as her base. Originally designed by Relius Clover, Lambda underwent a great deal of torture at the hands of scientists within the 5th Hierarchical City of Ibukido, and was eventually rescued by Iron Tager and Kokonoe who sealed her soul. After being killed by Yuuki Terumi while trying to save Ragna the Bloodedge, Lambda was revived inside the Embryo.

Lambda originally appeared in BlazBlue: Continuum Shift as a playable character, but was absent for BlazBlue: Chrono Phantasma. She reappeared in its remake, BlazBlue: Chrono Phantasma Extend, and onward. Lambda made her playable debut for BlazBlue Alternative: Dark War on November 11th, 2021.


Lambda's attire.

Lambda resembles Nu in nearly every way physically, except for her hair color, the tone of her skin, and her facial features. Lambda's hair is golden, similar to Noel's, her skin is a healthy light tan, and her eyes are wide open and bright.

Lambda's jumpsuit is identical to Nu's, but her cloak is very different. While it has the same collar as Nu's cloak, it has a golden piece of fabric resembling a necktie in place of the ring and talisman attached to Nu's collar. Unlike the one-piece cloak worn by Nu, Lambda's is split into 3 large folds, which are colored gold, black, and white. The two folds on the sides of her cloak are emblazoned with a large lambda letter and the text “No. 11” under it. Beneath that, in smaller text, is printed “MURAKUMO - UNIT ◄ idea DRIVE ► -2198-”.

Lambda's battle gear is completely identical to Nu's, except the color scheme is completely changed from shades of blue accented with green to black and purple accented with orange.


Silent and devoid of emotions, Lambda speaks in a very mechanical and detached manner, and is incapable of taking any kind of action without a direct command to do so.[3][4]

Opposite to her sister, Nu, Lambda is nearly always emotionless thanks to her memories being wiped by Kokonoe. She loyally follows Kokonoe's every order, and speaks in a cold monotone while using complex technical language. Nu's soul was initially injected into Lambda and sealed, but it has since disappeared. Because of Nu's soul, Lambda was able to develop some emotions, particularly towards Ragna. Unlike Nu's intense feelings towards the Grim Reaper, Lambda's is more subtle, and these feelings have persisted since her resurrection. Lambda felt so strongly for Ragna that she willingly defied Kokonoe's orders and sacrificed herself in order to save him.[5]

Time spent with Ragna, however, allowed Lambda to develop her own sense of identity. She displayed empathy and kindness towards both Ragna and an injured tartar, opting to spend to her own time trying to heal the insect instead of focusing on her primary directive to return to Kokonoe.

Before having her memories wiped, Lambda only knew suffering and was relentlessly experimented upon by scientists. She would cry out to be freed from the torture but she was unable to physically scream her terror. Thankfully, Lambda has no recollection of these events nor the trauma that was inflicted upon her.

Powers & Techniques

One of Kokonoe's strongest operatives, Lambda has abilities similar to those found in her sister, Nu. She is nearly always outfitted in bladed armor with multiple floating blades tailing behind her. These blades can be used in conjunction with Lambda's ability to summon swords from nowhere to attack opponents - simply put, Lambda attacks with a myriad of blades that overwhelms her opponents. With Kokonoe serving as the mission director, Lambda has a direct stream to her master which gives her an almost unlimited amount of knowledge at her disposal.

Lambda is one of the first to have been implemented with an Idea Engine, which was created by Kokonoe. It allows its user to have capabilities similar to those found in Nox Nyctores type weapons. With the Idea Engine, Lambda has some immunity to Phenomenon Intervention, but this ability is unstable.[6]

In Continuum Shift, Lambda functions as Nu's replacement and the two are near identical in playstyle. Lambda's Drive is Sword Summoner II, which makes her summons sword projectiles at long ranges. In Chrono Phantasma Extend, Lambda's Drive was renamed to Sword Summoner EX and had its function changed: while still fundamentally similar, Sword Summoner EX would create an additional projectile automatically after hitting an opponent. Lambda herself was also made stronger in close-range fighting than Nu. The two still share many moves, but the subtle differences mean the two of them play very differently.

Because Lambda's armor is made out of titanium and other light metals, her defenses are inferior to both Nu and Mu-12. She does not wield a Lux Sanctus: Murakumo either, making her the weakest in both offensive and defensive capabilities out of the three units who inherited parts of The Origin's soul. Like Nu, however, she cannot be absorbed back into The Origin since she has come to form her own unique identity. Lambda's weakness in combat compared to her sisters can be best demonstrated by her being killed from only two hits by the Geminus Anguium: Ouroboros.

BlazBlue: Central Fiction Library Entry


A bio-weapon created by Kokonoe.

An imitation of the ‘Murakumo' unit, built with the 11th Prime Field Device Tager retrieved during Ikaruga, combined with the soul of ν-No.13-, thought to have been lost at the Gates of Sheol. Furthermore, Kokonoe installed an IDEA Engine as a final resort and secret weapon against Terumi.

All of Lambda's memories deleted, Kokonoe uses her to carry out missions. That is, until she encountered Ragna, when ν-No.13-‘s memories began to resurface.

She is destroyed, protecting Ragna from Terumi's attack. That is when Ragna absorbs the IDEA Engine into himself.[10]

Appearances in other Media

  • The mobile game Mabinogi Duel stars Λ-No.11- as a playable card.
  • The action-RPG Fallen Legion Revenants features a DLC in which the Exemplar Valeria receives an outfit based on Lambda. This collaboration was likely made possible due to Arc System Works publishing the Japanese version.
