Jet Testania

Jet Testania( ジエット・テスタニア ) is a prominent character in the final arc of the web novel of Overlord, serving as the primary point-of-view character as well as the core focus for the arc's events.

Appearance
Jet is described as sixteen year-old teenage human boy with dark atmosphere, a sickly skin tone, and has bags under his eyes that receive mention on more than one occasion but regardless of these attributes he is still held to be handsome. His most prominent feature however, is an eyepatch he wears over a single eye.

Personality
Jet as a commoner often expresses his discomfort for the future and in general tends to view nobles negatively. In particular he cites how nobles are able to use their status to their advantage and the fact that a prominent noble classmate, Rangobart Eck Waria Roberbad, uses his somewhat notable noble family's prestige to attempt to coerce Jet's childhood friend Nemeru into dialogues and overtures. Additionally, Jet seems to dislike how nobles get to pay certain fees to take easier exams than students like Jet who must take difficult exams to ensure a free education. Compounding on that is how many nobles do not attend the Magical Academy for the education but merely to make connections, though nobles in the Magical Course Jet is in are outliers as they must demonstrate ability to be able to enroll compared to other courses.

Jet can also be described as observant as he correctly identifies the lack of sincerity in Rangobart's actions as he holds not true feelings for Nemeru. Additionally, he recognizes how little influence he has as a commoner. As a result he aims to join the Imperial Knight Order to receive the protection of the Bloody Emperor's reputation that would protect Jet from the repercusions of his meddling once he graduates from the Magical Academy's Magical Course. Until then, he relies on the protection of the Student Council President, Frieanne Waria Ran Guismondo, who coming from a distinguished family and approaching the third tier of magic has considerable influence while Rangobart a third son only approaching the second tier has less. This however will change the following year when Rangobart begins to advance further in his studies and Frieanne graduates while Jet remains a tier one user only and Nemeru has yet to even reach the tier one.

Thus, Jet constantly worries of how he can cope with the inevitalbe backlash from physically and metaphorically standing between Rangobart's desires and Nemeru. Nonetheless, due to his powerless commoner background all Jet can do is make lies and ignore the fallout of ruining his non-existent family reputation.

Jet is also very diligent, as he constantly works his part-time job making spices and salt with his magic as well as worrying about his studies. Unfortunately Jet laments that as he is too poor he cannot afford his own textbooks but cannot study in the library due to his work. Despite receiving offers of a promotion and stable job from his current employer going so far as to pay the necessary fees so Jet will not have to serve the Empire as part of his tuition agreement, Jet refuses as he know they cannot protect him from strong noble families like Rangobart's. In the mean time he agrees to borrow money from Nemeru whose sister has recently been hired by a powerful noble making him feel at ease with taking it so he does not overwork himself.

Jet can also be said to be quite compassionate as he frets over his dying mother's incurable illness that has bedridden her. Though Jet is troubled by how even the temples could not cure her despite the fees they charge, and state a higher tier is needed which is beyond the scope of a poor commoner like Jet whose father is also long dead. Jet contemplates even joining an Adventurer team and having a future teammate heal her as a favor to him, but dismisses it as he knows that Divine casters who heal without charging often meet with unfortunate ends or deaths in the Empire. Besides his mother, Jet also showed compassion for a young girl he saw being bullied by four nobles in school, standing up and using the fact Fluder joined his examination team as leverage to ensure her safety when he could not do so for Nemeru before hand.

Background
Jet was born to poor commoner family that you could see in many places. He had no siblings and his father died early on in his life. His mother fortunately worked for the Furt family, and Jet's magical ability was identified by the Furt family's eldest daughter, Arche Reb Elle Furt's talent. Additionally, she advised Jet about the risks of his own talent, that is the ability to see through illusions of people and objects at the risk of giving off a feeling that the illusion has been broken by his eye to the target. Arche warned him of the dangers of seeing through illusions people intended not to be broken and advised him to cover his sole eye that had the talent. She also told him his talent could be very useful should he work as a guard somewhere or with someone with powerful backing as it has no drawbacks on inanimate objects or others should he have protection.

There was also an older man Jet met that got him to take the Magical Academy exams despite his poor background. At some point in his life before this though, Jet somehow became childhood friends with Nemeru, a lower ranked noble girl from declining family.

As Jet was born slightly before the Bloody Emperor Jircniv came to power, he has lived through the reforms and noble purge that earned him the moniker. Jet primarily views Jircniv negatively not because he disagrees with his actions but that they resulted in his own circumstances worsening from the decline of the Furt family, the lowered position of Nemeru's family, and making some nobles act more brazen like Rangobart.

Chronology
Jet is first introduced as standing out in his classroom one day when lessons end for the day due to his appearance. Despite that, as the room emptied out and he eaves dropped on some classmates while waiting for Nemeru to finish up her cleaning duties for the day, he ponders his circumstances. When Nemeru shows up, his relief is short lived as Rangobart intrudes and attempts to solicit Nemeru as he is want to do. Unable to stop him directly, Jet can only preent Rangobart from actually getting Nemeru to speak to him so he forces Nemeru behind him and lies about her being busy. This leads to a verbal outburst from him, but due to the timely arrival of the student council president, who knowingly winks at Jet when he exclaims Rangobart was bullying, he leaves for his part-time job with Nemeru following him out.

At his job creating spices and salt with his magic until he becomes exhausted, Jet declines a job promotion yet again as he wants to graduate from the Academy and join the Knight Order to receive the protection of Jircniv's prestige to prevent repercussions from his actions. At his home though after work, Jet suddenly receives a knock at the door, and is greeted by an older man dressed in very elegant formal knight attire. The man was General Ray of the Empire's 8th Legion who came on behalf of the newly appointed Frontier Marquis ( a Margrave= Frontier Count for reference) equal to members of the royal bloodline of Dukes, Ainz Ooal Gown. They enter a carriage where Sebas awaits to propose a job offer to Jet at three times the pay the position normally entails. When Jet refuses, citing his desire to graduate, Sebas offers him the position at a later date, but declines again, but lets slip he may have trouble graduating.

Soon Jet's school life takes a drastic turn as the lauded and praised Fluder Paradyne joins Jet's class as a student no less, siting next to him. Through the awkward lessons where teachers often try to confirm the material with Fluder, Jet manages to make it to lunch. There he meets a friend in the cafeteria who tells him the gossip surrounding Ainz Ooal Gown. In the coming days many nobles attempt to introudcue themselves to Fluder and recruit him. Fluder nonetheless turns them down, even Rangobart. However, Jet feeling that Fluder coming to the Academy and being rumored to be connected to Ainz due to being a stronger magic caster (and General Ray being described in Ainz's small but growing faction after Jet reveals to the Student Council President his information and how his Talent may be the reason behind this supposedly super powerful, wise, and wealthy noble's interest in Jet) he gambles on the chance, and asks Fluder to join his end of term exam team, which he agrees to quickly.

This life continues, but after rescuing a girl Jet has never meant from four nobles named Honestia and getting her to join his team, Jet is promptly introduced to a mysterious girl named Nabe who forced her way into his team as well. Jet then receives another bombshell when Nemeru receives an invitation from Rangobart to a ball, but has to attend due to her father's joy at his daughter receiving an invitation to a prominent noble's ball. Jet decides to sneak into the party by getting Honestia's help, who somehow is able to get him a formal invitation. At the party though Jet is forced to take his eyepatch off and wear his formal Academy attire (an outfit proposed by an Emperor from ages ago and thus cannot be cricitized by nobles else risk angering the royal family), both split up, Jet thinks he sees his beloved senapi Arche. But before anything can happen, Nemeru finds him and surprises him in a gorgeous dress she borrowed from her sister's employer. She is so stunnign it causes even Jet to blush and not recognize her. Before thsi amounts to anything though, Jet spies Rangobart who may not be happy to see him, but his worries go out the window as the world around him seems to rust as he spots Rangobart acting subservient to what he thinks is an undead lich. Panicing, he lets out a yelp but realizes that only he can see the undead due to his talent and that the nobles would likely not beleive a commoner like Jet so he tries to devise a way to flee. Unfortunately, Rangobart finds them, and the pair approaches. Jet quickly lets his caution be known, even protecting Nemeru behind him to the undead's confusion who claims to be named Momon and attends his Academy. It soon dawns on Momon though that Jet can see hsi true face, thus Jet agrees to speak to him in private, when he feels Momon threatens Nemeru by bringing up her dress. Once alone, when Momon seems to try to coerce Jet into silence he asks what he wants, but Jet not trusting him decides to only say he wants Nemeru to be safe.

Soon after the ball, Jet has his end of term exam with Nemeru, Fluder, Honestia, and Nabe. He has an awkward conversation with Momon before they leave, and he quickly befriends one of the knights tasked with protecting them.

Along the way, the knight prys into which of the girls Jet likes and so on. The topic of the dragons of the mountain range come up as well, but Fluder brings up how they don't come down to the forest due to the rumors of a tree dragonlord, suspected to be a dragon with druid powers featured in very old literature, where even the fact it looks like a tree is questionable.

They then encounter goblins escaping from danger in the Tob Forest, and Jet with everyone's trust devises a plan to negotiate to prevent a fight. After a dialogue is formed, they describe how they were attacked, and upon seeing Fluder summon an Archangel Flame to verify the threat, confirms they were most likely attacked by the Sunlight Scripture to Jet's confusion. However, Fluder causes Jet to worry when the goblins reveal that there was a Gigant Basillisk as well which makes Fluder suspect the Black Scripture is involved and he warns the group of the dangers, especially if the rumors about the First Seat are true.

Trivia

 * Jet's talent to see through illusions gets references in the LNs. In particular Volume 6 when Ainz takes his helmet off to avoid Gazef's curiosity and in Volume 12 when Ainz inquires about illusion-seeing talents to the Holy Kingdom members.
