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. Her public identity is Eta Lloyd Wright, an award-winning architect through implementing mathematical and scientific principles taught to her by Shadow.

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 trousers in the anime, while they are 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 Wisdom" and conducting various research and development based on said 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 Cult of Diablos, Eta participated in the assault on the secret base where Claire was being held, along with her lord and the rest of the Seven Shadows. They managed to rescue Claire after they eliminated all Cult members and the leader of the branch base. Afterward, Eta would join her sisters in leaving Shadow for a duration to expand their influence to keep apace with the Cult's power.

Bushin Festival Tournament
In the anime, during the beginning of the Festival of the Goddess of War, Eta helps her lord Shadow, along with Gamma, Nu, Kai and Omega, to disguise him using a machine that molds the head of a person into someone else. With Shadow in the disguise he wanted, she retired to resume sleeping, wheeled off on a box dolly.

By the end of the festival, Eta communicated with the other Shadow Garden members in Oriana Kingdom using Morse code. Establishing a coded covert communications network across the continent.

Red Moon Incident
Eta was theorizing about the similarity between the Demon Possession and the Vampire Progenitor's blood, and informed Beta to look for information in the Crimson Tower of the Lawless City. Afterward, they started preparing an operation because their master intended to go there.

After the Blood Queen's rampage ended, Beta was able to recover the sample of Progenitor's blood and had already collected information from the tower's library to study further of her own theory's research of Demon Possession.

The research was proven successful as Alpha was able to use the 'Red Mist Form' technique. Able to use use it against John Smith later, and Zeta using 'Black Mist Form' during her fight with Delta.

Great Trading Company Conflict
Following the events of Delta's disappearance, Eta was given an encrypted message by Shadow from Beta written in an alien language (Japanese). 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 alien inhabitant from that world back with her. Alpha subsequently placed the Otherworlder under Beta's protective custody out of fear of what Eta would do if she got her hands on the alien.

Powers & Abilities
Due to 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
Eta has a habit of dozing off while either working or even during important meetings. She even has a habit of sleepwalking around the Shadow Garden's base and hit into wall, thus forcing the other members to retrieve her.

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, develop the "internal combustion engine" she heard about in "Shadow Wisdom," and also the "automobile" that uses the engine as a power source after Mitsugoshi discovered an oil field for their civil market when Gamma began expanding 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.

Mad Scientist?
When Eta was enamored by Shadow, she slipped him an aphrodisiac to manipulate him to love her. When she found he was immune, she intensified the "experiment" with fatal poison capable of killing dragons and discovered he was fully immune to that as well.

According to Alpha, the leader of the Seven Shadows was afraid of what Eta may do to their alien guest, Akane Nishino. This could hint that Eta's morals are flexible, given her sleep disorder affects her mood, and that she most likely would experiment on Akane as she casually did on Shadow.

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 without him knowing it. But seeing no reaction, she tried something much deadlier by making him drink a poison that could even kill a dragon, also ineffective. In the end, she resigned herself and was only able to collect the biological immunity that Cid had.
 * In the spin-off KAGEJITSU, Eta seems to notice Epsilon's fishy reaction whenever the topic of slime body and breasts are mentioned, although she is unaware of the former's secret.
 * Eta has knowledge about communication and language, such as Morse Code and translating a message in Japanese, completely alien to her world. It is speculated that Shadow taught her when they were young.
 * The morse code that Eta sends out at the end of final episode anime season 1 actually spelled out "To be continued".
