Beta

 is the third member of Shadow Garden, supporting her master Shadow against the Order of Diabolos. Outside of her Shadow Garden activities, she adopts the identity of Natsume, an up-and-coming author of numerous original pieces of literature.

Personality
Beta is a dedicated and loyal subordinate to Shadow Garden. She is both a great analyst, using information presented to her or she has gained from her missions, and a warrior, leading her team members to victory. While conversing with other, she remains calm and responds to them in a sophisticated manner. As Miss Natsume, she presents herself as a calm, humble young woman but won't hesitate to use her beauty to entrap her targets and get what she wants.

Beyond her loyalty to Shadow Garden is her loyalty to her master, Sid/Shadow. Beta is in love with him. She dreams of one day embracing into his arms with the most extremest of passions. Because of this, she gets extremely jealous at any girl that aren't from Shadow Garden, that attempted to get close to him, particularly Princess Alexia Midgard. While off or during her duty, she has a hobby of writing a book entitled "The War Chronicles of Shadow-sama".

Appearance
Beta is a beautiful young voluptuous Elf with green pupils and shoulder length silver hair with a left braid behind her ear, as well as a mole underneath the corner of her eye on the same side.

Her Shadow Garden outfit consists of a low cut dark slime suit that exposes her cleavage with golden decorations around her chest, shoulder, arms and waist.

While posing as Natsume, her civilian attire comprises of a white ruffle blouse that also reveals her cleavage, a dark mini-skirt skirt, black stockings and high heels. Additionally, she also adorns a pair of glasses and necklace, as well as a scarf around her waist.

Tragic Childhood
During her childhood, the girl, later known as Shadow Garden's Beta, was living with her family in the country of elves where she would also become acquainted with another future member, Alpha. However, after contracting Demon Posession, she would be persecuted by her family and society before being exiled from her home.

Fortunately, Beta was eventually rescued by Alpha and her friend's master, Cid Kagenou, the leader of Shadow Garden, where she would also be cleansed of her Demon Posession. Although the young elf was initially frightened by Shadow, she would slowly come to accept and care for him while training under his tutelage. Furthermore, along with Alpha and Gamma, Beta would participate in the planning of expanding the organization to further their resistance against the Order of Diabolos.

Assault on the Order
After her master's elder sister, Claire Kagenou, was abducted by the Order, Beta later meets with him to report the results of Shadow Garden's investigations. Supported by Cid's insight, they are able to determine the location of their enemy and his sister's location.

Afterwards, Beta, along with the other members of Shadow Garden, would participate in the assault on the Order's hideout, eliminating many of their members before confronting the culprit behind the kidnapping, Count Olba. Despite the cultist's escape, the girls allow him to proceed, realizing that their master had foreseen the count's actions and leave the issue to Shadow to handle.

Following the successful rescue, the Shadow Seven would later report the fruits of their research into the Order of Diabolos to Cid. Determining that leaving was necessary in order to expand the organization, the girls would tearfully depart after recieving permissions from their master. Beta, in particular, would become a popular author under the pen name Natsume for writing numerous novels in different genres based on the stories told by Shadow.

Kidnapping of the Princess
Several years later, Beta would reunite with Cid as he was being framed by the Order for the abduction of Princess Alexia Midgar, discovering him among a collection of rare antiques and luxury items to her admiration. Supporting Shadow Garden's raid on several of the Order's secret locations, she was able to witness her master eliminate several members during another attempt to entrap him, while recording the event in her secret chronicles. Following the incident, the two would separate and she would continue to support the operation.

The Holy Ground Infiltration
Beta later participated in the plan to infiltrate the Holy Ground. Her task was to attend the Trial of Goddess under the guise of Miss Natsume and spy on target, archbishop Nelson. Before she left for her mission, she informed her beloved master about it. When she arrived, Beta interacted with Princesses Rose Orianna and Alexia Midgar who she has animosity with due to the latter having dated Sid.

When Shadow revealed himself into the arena, Beta was shocked and puzzled about his actions. Nonetheless, she remained calm and continued the plan. She began writing down information that she gained after observing the battle between Shadow and Aurora. Once Shadow escaped the Holy Knights, she signaled her comrades to strike. Epsilon successfully captured Nelson while Delta took Beta as a hostage to ensure suspicion was diverted from her.

The group entered the Holy Ground to learn about the origins of the Three Heroes and the Order of Diabolos. After Nelson freed himself and started to attack, Beta lead Alexia and Rose to safety while Shadow Garden fend him off. Following the destruction of the Holy Ground perpetrated by Shadow, Epsilon reported to Alpha that Beta was escorting the princesses.

The God of War Tournament
After the incident at the Holy Ground, Beta became part of a group with Rose and Alexia. When informed about Rose's attack on Doem, she tries to prevent Alexia from intervening until the princess manages to convince her. The two girls head into a tunnel and found Rose defeating Doem's men using a new power which Beta realized to be Shadow's work. Once Alexia was defeated, Beta allowed Rose to go while she tended to the princess. Beta decided to inform Alpha about Rose.

The Red Moon Incident
Beta lead a team to research on vampires' blood in hoping to test out a theory that can help in the war against Diabolos. She informed Sid about it who ordered her to be vigilant when the Red Moon is upon them. She was later seen by Claire and Milia, researching on vampires. After 666 (Rose) exposed herself due to overreacting about Sid's abduction by the vampires, Beta reprimanded her.

After Queen Elizabeth was resurrected. Beta commanded her team to attack the vampire with futile results. Even with the combined might of the two monarchs of Outlaw City could not inflict harm on her. Shadow finally arrived to turn the tide, even rescuing Beta and her team from certain death. The chaos finally ended when Shadow cured Elizabeth from her vampirism, rendering her human. Beta smiled for Elizabeth's newfound life and leave with her team along with the blood sample they managed to obtain during the fight.

Mitsugoshi Co vs Great Commerce Alliance
Beta aided in the operation of bringing Mitsugoshi Co into the height of its power. She successfully ambushed Garter private corp, killing all but three of them for interrogation. She then returns to Sid, informing him of Delta's presumed death. Sid in return gave her a code for her to decipher. With help from Eta, Beta learns Sid's plan to cripple the Great Commerce Alliance and informs this to Alpha and Gamma.

Abilities
Beta has shown to be a great leader, ordering commands to her squad and reprimanding should they disobeyed her command. She is a master infiltrator, having deceived people with her meek and shy Miss Natsume. By the time they realized her true identity, Beta would have effectively and quickly kill them.
