Eta

Eta (イータ) (Ήτα) is the seventh member of Shadow Garden, being one of the original "Seven Shadows", as well as the person in charge of the organization's research faction. Publicly, she is known as Eta Lloyd Wright, a genius architect whose work won Architecture of the Year.

Appearance
Eta is a female elf with long brown hair with bangs and purple eyes under a continuously sleepy gaze. In her civilian attire, she dresses as a scientist as she is in her lab most of the day, reverse engineering and adapting the innovations of Shadow's Wisdom. In her room, Eta is a lazy dresser and often times just wears the clothes she went to sleep with.

For Shadow Garden, she is adorned in the customary Slime Bodysuit with a stylized cloak and scarf, having frills and minor decorations along the cloak of her bodysuit. On the back of her bodysuit, the belt extends and almost appears as a tail. Her coat has large sleeves but drapes over her shoulders, the back of which has a tattered look at the base to appear as though it were torn, while her scarf is cartoonishly large. In terms of her attire at the torso, the light novel has it appear similar to a professional dress which ends at the hipline, while the anime has it appear like a unitard similar to Beta. Her belt hangs low along her hips in the light novel, while the belt meets her waistline in the anime with two coupled belt circumventing around and behind her hips. Eta has two decorative smaller belts around her femur-- her left leg in the light novel, and her right leg in the anime. Eta has simplified ink gray/black for trousers, cuffed pants curing up and outward in the light novel, while having riveted fins along the back; from the kneecap, down the achilles, ending at the ankle. Eta's footwear in the light novel seems akin to professional businesswoman heels like Gamma's, while the anime has her wearing high heeled platformed shoes with a single gold trim at the metatarsal joints of the shoes.

Personality
Eta is slow-paced, shown by how when she falls asleep that she is not easily woken. This is attributed to a circadian rhythm disorder affecting her body's clock. But despite her fatigue, Eta is expeditious in her research, as within a few years after the rescue of Claire Kagenō, Eta took "Shadow's Wisdom" and developed technologies based on his past life to be used in their world, such as the instant camera and the automobile, which she applied the technologies to Mitsugoshi publicly, while equipping Shadow Garden secretly.

According to Alpha, Eta appears to be somewhat of a mad scientist, as she has a motto which its says that "development always comes with sacrifices" and prepares for a drugs and experiments among her friends, even fearing what she would do to their newly-captured Earthling if she got her hands on her. Eta loves doing the "V" peace sign, as it stands for “Victory”.

Eta is interested in the "science" when she heard from Shadow's "Shadow Wisdom" and conducting various research and development based on "Shadow Wisdom". When it comes to things that interest Eta, such as architecture and research, she immerses herself in them without even having time to sleep.

First Assault on the Cult
After her master's elder sister, Claire Kagenou was abducted by Viscount Grease from the Order of Diabolos, Eta participated in the assault on the secret base where Claire was kidnapped, along with her lord and the Seven Shadows. They managed to rescue her, after they eliminated all members and leader of the branch base.

Great Trading Company Conflict
Following the events of Delta's disappearance, Eta was given an encrypted message by Shadow from Beta. After Eta decoded the message, it was discovered that the message was Shadow's explanation on his 'betrayal' and the deciphered parcel was forwarded to Alpha and the other Seven Shadows.

Return to Earth
After Beta returned from her adventure in another world with Shadow, she brought an inhabitant from that world back with her. Alpha subsequently placed the Otherworlder under Beta's own custody, out of fear of what Eta would do if she got her hands on the alien.

Powers & Abilities
As a result of her sleeping disorder, Eta is arguably the second-weakest member among the "Seven Shadows", with only Gamma being lower. Instead, her strength lies in her intelligence, inventing and reverse-engineering things for Shadow Garden using the Shadow's vague descriptions of Earth.

Physical Ability / Slow Pace
Due to suffering from a sleep disorder, Eta is only active at indeterminate intervals. However, when she does participate in combat, she can keep pace well enough with her fellow Shadows.

Resourceful Intellect
Eta is arguably the smartest member of Shadow Garden, which is already saying a lot. She is the organization's head scientist, researching the Slime Bodysuits based on what Shadow previously created when he first started. In addition to developing several types of Slimes by applying the slime technology invented by Shadow, she is also involved in the construction of each branch of the Mitsugoshi Company as Eta Lloyd Wright in the public society, as a "rare architect".

With limited information, Eta was also able to reverse engineer an instant camera for Shadow Garden espionage, also develop the " internal combustion engine " she heard about in "Shadow Wisdom" and the "automobile" that uses it as a power source after discovered an oil field for Mitsugoshi's civil market when she began to expanding it into the Velgalta Empire.

Eta is also a master translator, able to "decipher" Shadow's message written in Japanese, an unfamiliar language, far faster than even he had anticipated whilst no one else was even capable of it.

Swordsmanship
Like the rest in Shadow Garden, Eta is trained in the sword but has limited practice due to her infrequent sleeping.

Magic
Being a direct pupil of Shadow, Eta knows some degree of magical utility. Especially since the Slime Bodysuits require conscious magical control to be shaped upon the user.

Cid Kagenou / Shadow
In general, Eta is a lethargic person who rarely shows interest in anything other than her projects. This changes radically when she is with Cid, since listening to his "Shadow Wisdom" is her greatest joy and pleasure, as she could spend whole nights without sleep only to listen to Cid.

Alpha
The leader of the "Seven Shadows". In the anime, the two maintain a cordial relationship. However, Alpha has shown to be somewhat wary of Eta due to her seeming lack of morals.

Beta
A fellow member of the "Seven Shadows". While Eta's views on Beta are unknown, Beta has shown respect for her intelligence yet also somewhat fears her due to her seeming lack of morals.

Gamma
A fellow member of the "Seven Shadows". While Eta's views on Gamma are unknown, the latter dislikes how much of Shadow Garden's finances the former wastes on her experiments. But this is adequately compensated with the technologies she develops, both for Shadow Garden and Mitsugoshi.

Delta
A fellow member of the "Seven Shadows". In the anime, Eta and Delta have a somewhat troubling relationship, as the latter often has trouble understanding the former's scientific remarks due to her low intelligence. In turn, Eta has shown to become uncharacteristically angry whenever Delta accidentally breaks one of her inventions.

Epsilon
A fellow member of the "Seven Shadows". In the anime, Eta and Epsilon maintain a cordial relationship. However, Eta has been shown to get angered whenever she feels like Epsilon is mocking her inventions.

Zeta
A fellow member of the "Seven Shadows". Eta remains unaware that Zeta is going behind her and the other members' backs by creating her own faction within Shadow Garden loyal solely to her.

Trivia

 * Her architect name of Eta Lloyd Wright is likely derived from the American architect: Frank Lloyd Wright.
 * In general, Eta does not show any high or strong emotion, whether it is a positive or negative response towards others or the members of Shadow Garden. As of now, the only person who can inspire strong feelings in her is Shadow.
 * Despite the fact that Eta only shows her strong emotions in front of her lord, Shadow, she has also shown a maniacal interest in her own master, not only in love, since she wants to know about the biology of his body. During the quotes from Vol 5, Eta wanted to inspect Cid's body in a possible way, first making him drink an aphrodisiac in his drink without him knowing it. But seeing that it didn't work, she tried something much more deadly, making him drink a poison that could even kill a dragon, which it also didn't work either. In the end, she resigned herself and was only able to collect the biological immunity that Cid has.
 * In the spin-off KAGEJITSU, Eta seems to notice Epsilon's fishy reaction whenever the topic of slime body and breast is mentioned, although she hasn't known about the former's secret.
