Λ-No.11-

λ-No.11-, commonly abbreviated as Lambda-11 is a Murakumo Unit imitation 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, eventually being rescued by Iron Tager and Kokonoe who sealed her soul. After being killed by Yuuki Terumi to save Ragna the Bloodedge, Lambda was revived inside the Embryo, and currently lives as a nun with Noel Vermillion, caring after Nu-13.

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 onward.

Central Fiction
Resurrected inside the Embryo, Lambda lost the recollection of her death and her memories were altered to believe that Bullet had always been a member of Sector Seven. She still served under Kokonoe and became one of the chosen. She alerted Kokonoe to a change in seithr concentration within a distorted Kagutsuchi. Kokonoe sent her inside the Embryo floating above Ibukido and retrieved her. Much later on, Lambda was reunited with Ragna and she helped him, Tsubaki Yayoi, Hakumen, Ex Machina: Minerva, Jin Kisaragi, Kagura Mutsuki, Rachel, and Noel enter the Embryo’s frozen space-time. She held open the entrance by linking her Idea Engine to Tager’s.

Lambda watched Tager evaporate into seithr during Doomsday and had her data backed up by Es before she too disappeared. Lambda was reborn in the new world created by Ragna the Bloodedge, becoming a nun alongside Noel. The two of them watched over Nu, who is currently in a catatonic state. They had a visit from Tsubaki and Makoto, offering them dinner that night.
