Beta

The second seat of the Seven Shadows. Ages from 13 to 15. An elf with short, silvery hair who writes heroic tales about Shadow every time something happens. Alpha has known her since before she was possessed by a demon. Among the Seven Shadows, she is one of the most devoted to Shadow. Although her combat skills are high, she is not interested in combat itself and does not practice on her own, but faithfully follows the combat techniques she has been taught, handling various tasks adeptly, hence her nickname "Solid." In "Master of Garden," she mainly forms large bows and arrows with slimes and engages in long-range combat.

After joining Shadow Garden, she was initially unable to sleep due to being unaccustomed to killing people, but Shadow helped her by telling her various literary works as bedtime stories. Later, using these as a basis and leveraging her own literary talent, she published them to great success. Thus, she gained fame as the popular novelist Natsume Kafka, who publishes works in a wide variety of genres and is popular among both men and women.

Being a popular novelist makes it easy to gather information, and her status allows her influence in the upper classes. Using connections from the reporters at the "Yominichi Newspaper Company," where she regularly publishes her novels, she collects information not generally disclosed to the public. As a result, although it is a disguise, she understands the circumstances of Alexia, who has become Shadow's lover, and dislikes her but has become friends with Rose without revealing her true identity.

During the turmoil in the Oriana Kingdom, she followed Shadow, who had jumped into the Black Rose, and reached the real world, which is Shadow's previous life. Acting as siblings, she brought Akane Nishino back to her own world.

While acting as Natsume, she gives a gentle first impression, but she has a cunning side and sometimes subtly disparages Alexia.

Among the members of Shadow Garden, she has the largest bust and uses it as a honey trap to extract information from others.

Beta and Epsilon compete for Shadow's attention, and due to Epsilon's one-sided hostility (because of bust size), Beta has also started to feel a sense of rivalry. In the TV anime version, their conflicts are depicted as a common sight, and those around them do not particularly care. In the Oriana Kingdom, the two are also acclaimed as the leading emerging figures in the art world.

While not as much as Eta, she is quite intelligent and learned to speak Japanese, albeit brokenly, after just a few days in the real world. Because of this, she later became the caretaker of No. 712.

Volumes 1 to 4 of the book version include "Shadow-sama Chronicles," heroic tales about Shadow written by Beta.

In the TV anime version, in the second season's twelfth episode, she is depicted as stunned along with her companions when Shadow is swallowed by a vortex leading to the real world. She did not appear in the real world, but in "Kagejitsu! Second," she and Shadow go missing, apparently having gone to the real world as in the original work.

She addresses Shadow with respect.
