Often times, she'll have her left eye open and routinely analyzes whomever crosses her vision, such as Rose Oriana when she joined Shadow Garden.

Personality
Being that she was formerly a military officer in the Velgalta Empire, Lambda is a strict instructor and harsh towards trainees, given her background and to ensure they're up to whatever tasks soon follow. Such as Rose Oriana, 665, and 664.

Whenever someone joins Shadow Garden's ranks, Lambda will not inquire into their past, as all numbers are just that, with who they were originally being knowledge privy to the executive officers, like Alpha, Beta, Gamma, and Epsilon, since that was the order given in part to avoid continuing to suffer from their hard past that they had, because of the Cult. Although some members, especially the newly new ones, it is not easy for them to discard everything. As a member of the Shadow Garden, she is very obedient towards her superiors.

Even though Lambda is feared by the other members because of her harsh teaching style, she is kind enough to acknowledge when any members perform well.

Searching for a New Base

When the Seven Shadows sought a new location for a secret headquarters, Lambda was among the chain of command and gather members who are at least adequately trained. As Delta and Zeta went ahead to find the source of the barrier from the Abyss Wood, Alpha ordered Lambda and all the members she brought to retreat and relay the situation to Shadow if there was no news within three days, while the Seven Shadows would conduct an investigation.

When her master defeated the Mist Dragon that guarded the ancient capital of Alexandria, Lambda was as ecstatic as the others in Shadow Garden to have more space and living quarters for the membership.

Bushin Festival Tournament
After the Bushin Festival, Alpha brought Rose Oriana to the secret city of Alexandria, the hidden headquarters of Shadow Garden. Ignorant to her true identity, Lambda carried out Alpha's orders to train Rose and renamed her to Number 666, and assigned her to partner with 664 and 665 as a new team.
