Lambda

One of the Numbers. 23 years old. A dark-skinned elf who was first un-cursed and saved by Epsilon. She is blind in her right eye, which is always closed.

Formerly a high-ranking military officer of the Begalta Empire, her real name is Zinaida. Utilizing her experience as an instructor, she serves as a trainer for new members in Shadow Garden and also acts as a spy, using her knowledge of various countries' geography and political situations. Sometimes, she is consulted by Alpha as a military advisor. In the third part of Chapter 1 of the "Seven Shadows Chronicles," she officially starts operating as the "Military Command," and is seen teaching Delta's hiding techniques to the members.

In the original work, she focuses on training new members and does not go outside Alexandria, so there is no direct interaction with Shadow. However, in "Master of Garden" of the Seven Shadows Chronicles, she meets Shadow for the first time and is able to converse with her. Shadow's first impression of her was "demon sergeant." When active outside, she dresses in a suit.

In the TV anime version, her role has significantly increased. In the first episode of Season 2, she participates in a meeting with Shadow and the other Seven Shadows, creating interactions. In the eighth episode of Season 2, she serves as a referee for beach volleyball and performs various chores such as reading the narration for a shadow play. In the tenth episode of Season 2, she disguises herself as a bus guide and sends her subordinates to the Kingdom of Oriana.
