Gamma

Gamma (ガンマ) (Γάμμα) is the third member of Shadow Garden, being one of the original Seven Shadows. Publicly, she is known as Luna, the director of the Mitsugoshi Company which sells products reverse-engineered using the Shadow's descriptions of Earth.

Appearance
Gamma is a mature-looking young woman with a slender figure, large bosom, and dark blue hair with several strands braided that extends nearly to her feet. Furthermore, she also possesses a mole under the left corner of her lips.

Her Shadow Garden uniform consists of a standard slime bodysuit with golden patterns decorated around her chest and arms. Outside of Shadow Garden, Gamma normally wears a long dark dress attached to a checker that exposes her chest and back.

Personality
Gamma is seen as a dignified person with elegance and grace, but in actuality, she is very clumsy, affecting her performance in battle. Although not a competent fighter, she makes up for it by being a very intelligent and cunning individual making her the one responsible for most of Shadow Garden's operations.

Background
After being left for dead by society, she was discovered by Cid Kagenō. He revitalized the girl causing Gamma to develop a deep admiration for the power Cid Kagenō possesses which she regards as life itself.

Being one of the original seven members of Shadow Garden, Gamma has spent time training with Cid and the other girls, particularly Delta. Gamma was dismayed that she is not a competent fighter like them. That is until Cid showed her another path through intelligence. Gamma listened to Cid's Shadow Wisdom from economics to engineering and decided to pour her dedication into learning them.

Assault on Viscount Olba
Gamma took part in rescuing Claire alongside the Seven Shadows. She and her team took care of most of the guards while Cid killed Olba.

Midgar Academy Terrorist Attack
Gamma reintroduces herself to Sid when he entered one of Mitsugoshi's stores. Believing he came to inquire about the attacks done by killers pretending to be Shadow Garden, she told him what they know. After Sid informs them that he has a lead, Gamma sends in Nu to assist him.

She then set up an operation to save Midgar Royal Spellsword Academy from a terrorist attack perpetrated by the Order of Diabolos. After the school was saved, she and Alpha discuss their master's triumph over the terrorist leader and gave smile with respect for him.

God of War Tournament
Sid visits Gamma once more and orders her to help him enter the God of War Tournament. She helps him by changing his appearance and identity.

Mitsugoshi Co. vs the Great Commerce Association
Gamma and Shadow Garden decided the time was now to place their company on top of the business world. Mitsugoshi Company currently has a strong standing due to its creation of the popular banking notes. This led the Great Commerce Association to send in assassins to kidnap her but Gamma with the help of Nu foiled the attempt.

She then received word of Delta's disappearance, greatly worrying her. This grew worse when she learned that Shadow seemingly abandoned which was undone when Beta told them the truth. Gamma expressed happiness that Shadow was still loyal to them and that Delta is alive. After Great Commerce collapsed, Mitsugoshi Co became the most successful business.

Great Intellectualist
Gamma's natural trait is her intelligence. This made her excellent at multi-tasking, extracting knowledge from her opponents, and planning out strategies ahead of time. Apart from her military brilliance, she is adept in entrepreneurship with the establishment of Mitsugoshi Co as proof of that. She applies fundamental economics she learned from Cid to her business such as the banking system which became popular among the populace.

Swordswoman
In the game, she uses a large nodach.

Magic
Gamma has tremendous speed and lots of magical power, which is offset by her lack of fighting skill or ability. Not helping this is her clumsiness which at the same time makes her a bit more unpredictable such as when she fell and threw her sword in such a way it bisected her assassin.

Nu
Nu is a high-ranking member of the Shadow Garden and carries double-digit number, ranking just below the Seven Shades. Nu serves as Gamma's assistant and personal bodyguard, as she is incapable of fighting.

Cid Kagenō / Shadow
Gamma deeply admires her lord after the latter discovered her and rescued her when she was discarded by society. Being enveloped by Cid's power causes her to tear up immensely. Gamma viewed Cid as an intelligent man and is frustrated at herself for not being able to keep up with his prowess, though he is pleased when he praised her business savy.

She is heartbroken upon learning Cid betrayed Shadow Garden but upon later discovering that he hadn't and had a secret plan to help them, Gamma cries in joy and her admiration had only increased.

Alpha
Gamma serves as Alpha's right hand when it comes to managing Shadow Garden, in that sense, she is responsible for the financial and administrative affairs of the organization as well as the head of its operations in foreign countries. Gamma highly respects her superior and they are able to get along.

Delta
Both Gamma and Delta did not get along when they were younger, due to Delta picking on her for her lack of combat prowess. However, they eventually got over that and treated each other like siblings. When Gamma thought Delta had been killed, she was completely devastated and overjoyed when Delta returned alive.

Eta
Like most of Shadow Garden, Gamma disliked Eta's use of them in her experiments. However, she was also annoyed with the Elf for spending much of Shadow Garden's funds to carry out her experiments.

Trivia
