## Plot

After a devastating war, there has been a realization that weapons are now too powerful and destructive. Thus ends the era of war fought in the "light" and begins the era of war fought within "darkness", a war fought with information and trickery, a war of spies. After the destruction of the spy team Inferno, their only surviving member, Klaus, sets off to create a team who specializes in "Impossible Missions". Impossible missions are missions that a spy team has already failed thus leading to higher security resulting in a chance of failure to be 90 percent.
The problem? The seven girls that Klaus has recruited are all washouts and bottom of the barrel for the spy schools they hailed from. Klaus only has a month to teach them everything he knows and in turn the girls will have to employ every possible trick to have a chance of surviving.

In the Din Republic, master spy Klaus is given an "Impossible Mission" which if he manages to pull off, will cement his reputation as the "Greatest Spy in the World". As part of this mission, Klaus gathers seven young spy cadets who are struggling in training, including a girl named Lily, into a team codenamed Lamplight. He explains that he will help train them to prepare for an Impossible Mission in the Galgad Empire, but while he proves to be a master spy, he is actually a poor teacher. Thinking that Klaus intends to use them as sacrificial pawns, Lily ambushes Klaus with poison gas in an attempt to force him to disband Lamplight. However, Klaus reveals he already saw through Lily's ambush, but he is impressed how she took the initiative to try and improve her situation, which gives him inspiration on how to teach the other students. The next day, Klaus installs Lily as the team leader for Lamplight and assures them that he won't let any of them die. In order for them to learn the skills they need, Klaus challenges the students to defeat him in a game of espionage. Part II: For the next five days, Lamplight works together to try and ambush Klaus, but with little success as he easily thwarts their plots. Eventually, the team starts to get frustrated until Lily suggest they actually try investigating Klaus' background. Meanwhile, Klaus is briefed by his superior C that the Galgad Empire stole a sample of a deadly bioweapon from the Din Republic called Abyss Doll, and the Impossible Mission is to retrieve the sample before the Galgad Empire can reverse engineer it. Klaus then returns to Lamplight and comes clean with them, revealing that he is a member of Team Inferno, the Din Republic's best spy team. However, the rest of Inferno was killed trying to retrieve Abyss Doll, and he accepted the mission in order to avenge them. Lamplight, having already learned of his connection to Inferno and inspired by his resolve, agree to follow Klaus. The team then infiltrates the Galgad Empire to collect information on the Endry Lab where Abyss Doll is stored. The night before the mission, Lamplight invite Klaus to attend a party so they call relieve their built up stress. Klaus arrives to find the girls asleep, and he remembers a lesson he was taught where a person willing to sleep in front of another is a sign of ultimate trust. Klaus once again swears to get the entire team home safely. The next night, Lamplight and Klaus prepare to infiltrate Endry to retrieve Abyss Doll. Part III: Klaus and Lamplight infiltrate the complex, but Lamplight is intercepted by Klaus' mentor, Guido, who reveals that he had betrayed Inferno and switched sides. In addition, he had arranged for their headquarters to be bugged, so the Empire already knows all of their plans. Regardless, Lamplight decides to fight back but are quickly neutralized by Guido. However, as Guido gloats over his victory, Lily reveals that they had already suspected there was a traitor within Inferno and acted accordingly, hiding the existence of an eighth member named Erna who stabs Guido. Klaus then arrives, having recovered Abyss Doll and orders Lamplight to escape with it while he deals with Guido. Slowed down by his wound, Guido is no match for Klaus, and after being defeated he saves Klaus from a sniper, taking the hit himself and dying before he could reveal why he betrayed Inferno.

Klaus and Erna are then captured by kidnappers, though Klaus figures out they were tricked by Lamplight into attacking him.

Klaus, Lily, and Sibylla then chase him into the forest. Part III: Corpse manages to escape into the forest, leaving the girls with no choice but to keep protecting Uwe until he makes his next move. Head maid Olivia later confronts Grete about refusing to mingle with male guests at a dinner party, and Grete tells a partial lie that she's in love with another man. Later that night, Corpse attacks again, but Uwe is saved thanks to Sibylla's intervention. Olivia then openly becomes suspicious of the girls, warning Uwe how they are acting uncharacteristically calm despite the attempted assassinations. However, Grete points out Olivia's odd behavior as well, and she backs off. Lily, Sibylla, and Sara then secretly confront Grete, suspecting she has been hiding part of the plan from them. Grete admits that she had disguised herself as Corpse and initiated the two previous assassination attempts in order to flush out the real Corpse hiding among the mansion staff. Her cover blown, Olivia attempts to kill the girls with grenades. When Lily suggests they summon Klaus for help, Grete tells her that Klaus will not be coming, so they will have to handle Olivia on their own. Part IV: Grete reveals that Klaus was never present, and that she had been impersonating him during their mission briefings in order to throw off Corpse. In addition, Olivia is one of Corpse's accomplices. Trusting Grete, Lily, Sibylla, and Sara to be able to handle Olivia themselves, Klaus left on a second mission with the rest of Lamplight to take down Corpse. As she flees, Olivia recalls how she first met Corpse when she stumbled onto one of his assassinations and fell in love with him, becoming his apprentice. She manages to evade Lily and Sibylla and confronts Grete directly. Grete lures Olivia into a situation where she thinks she has the advantage, until she tricks Uwe into shooting Olivia. Grete then reveals a disfiguring birthmark on her face, which she honed her disguise skills to hide. Klaus then arrives with Corpse in his custody, and reveals he was awed by Grete's dedication to hiding her birthmark before capturing Olivia. Afterwards, Lily arranges for Klaus and Grete to go out on a date, where Klaus makes it clear he holds no romantic feelings for Grete or anybody else. However, wants to consider Grete as part of his family and reiterates that he thinks she is beautiful despite her birthmark, which makes Grete happy. |||||||

However, they are dismayed to discover that the baker who makes the meat pies has recently been harassed by the president of the Mannheim food corporation, who is attempting to coerce him into selling his meat pie recipe. Too old to deal with the harassment, the baker considers closing down permanently which Grete cannot accept since the bakery is important to Klaus. Working together, Lamplight craft an elaborate con to sell a fake recipe to the Mannheim president. The plan is mostly successful, with Lamplight stealing the president's money, though Lily is forced to use knockout gas on him when he pulls a gun on her. After the conclusion of the mission to eliminate Corpse, Grete returns to the bakery to get a meat pie for the rest of Lamplight, and is pleasantly surprised to see that the baker has taken on an apprentice to continue his business.

| Part I: With the second team still missing, C considers declaring them traitors, but Klaus assures him that he can solve the issue himself. He then explains Lily and her team what the second team had been doing. Shortly after Lily's team left, Klaus designated Thea to lead the second team and issued a test where they would need to touch his hand before the end of the day. However, Monika, Erna, and Annette were notorious in their respective academies for having poor teamwork. Consulting with Klaus, Thea revealed that she wanted to become a spy after being saved once by Klaus' superior, Hearth. Klaus advised that Thea should be more direct with her teammates to get them to work together. She used her ability to discern people's desires to win over Erna and Annette, though she is troubled at how childlike the amnesiac Annette's desires are. Thea attempted to lure Klaus into a trap, only to learn that Monika had already pulled off her own plan, forcing Klaus to shake her hand after she sabotaged all of the mansion's faucets while using the others as a diversion. Klaus decides to take Lily to look for Thea's team while the others take care of his other missions. Meanwhile, Thea's team are relaxing at a swimming pool when Annette is suddenly hugged by a woman claiming to be her mother. Part II: As Klaus and Lily head out to search for Thea's team, Klaus learns that spies from Lylat and Galgad recently had a covert battle in the city, making the situation dangerous. At the pool, the woman identifies herself as Matilda Barbet, a mechanic from Lylat. While she doesn't intend to hand Annette over, Thea does agree to let Matilda have dinner with Annette in hopes that Annette connecting with her mother will give her a stronger motivation to be a spy. However, during the dinner, Thea and her team notice Matilda is being followed and help her elude her pursuers. Matilda admits that she is being chased by debt collectors because her toolbox was stolen and she was tricked into pawning off her passport in an attempt to get it back. Thea and her team decide to retrieve her toolbox and return it to Matilda. However, Monika reveals that she recovered Matilda's passport but the name on it doesn't match Matilda's, meaning she is a Galgad spy. Part III: Klaus and Lily arrive in the city, where they notice a covert but heavy military presence and meet their leader, Welter Barth from Military Intelligence. Welter informs them that the military is hunting a Galgad spy loose in the city, and Klaus already suspects the spy has a connection to Annette. Earlier, Thea and Monika come to a disagreement over whether to turn Matilda in to the military or not. Monika gives Thea and Annette one more day to come to a final decision before she reports to Klaus. Thea and Annette meet Matilda again, and she admits that she became a spy in order to support to Annette, and promises to retire if she can escape the Republic with her. Thea recalls the time she was saved by Hearth and how she wanted to become a hero like her, and both she and Annette decide to save Matilda. Thea and Monika then have a confrontation, and Thea is able to figure out that Monika is secretly in love with somebody in Lamplight. An embarrassed Monika agrees to go with Thea's plan to keep her secret, but warns that somebody will eventually take advantage of Lamplight's kindness. The next day, Thea assures Matilda that they will help her escape the country if she promises to retire as a spy. However, it appears that Matilda is actually manipulating Thea and her team. Part IV: Thea and her team plan to smuggle Matilda out of the country by ship. Meanwhile, Klaus and Lily investigate a murder scene where the thieves who had targeted Matilda had all been killed. Klaus figures out that Matilda is manipulating Thea's team, but decides to prioritize neutralizing the Galgad agent sent to back her up. Meanwhile, the backup agent White Spider meets Matilda, and she admits she doesn't truly love Annette and is actually responsible for her amnesia through repeated beatings. That night, White Spider attempts to snipe Thea but is stopped by Klaus, who recognizes him as a member of Serpent and the sniper responsible for killing Guido. Meanwhile, Monika distracts the military while Thea and the others get Matilda to a shipping container, but Thea realizes too late that Matilda is manipulating them and has no choice but to let her go. White Spider also manages to barely escape Klaus by using a bomb as a distraction. Afterwards, Klaus tracks down Annette, as he has figured out that Annette already knew Matilda was lying and manipulated everybody to ensure Matilda's death, killing her with her own bomb. Klaus praises Annette, as she possesses the ruthlessness the rest of Lamplight lacks. As Lamplight returns home, Klaus encourages an embarrassed Thea that she can atone for her mistake by succeeding in her next mission. |||||||

Two months earlier during the first Impossible Mission, Monika was tasked with getting close to electrical engineer Jordan Cupca through his son Mattel to collect more intel on Endy Laboratory. She manages to befriend Mattel after saving him from bullies, and agrees to help teach him self defense techniques. Monika recalls her past as an artist's daughter, and how she can easily copy skills but couldn't find any passion for art so she became a spy. However, during training, she was confronted by an expert spy who warned her about lacking passion in spycraft, causing Monika to lose motivation and wash out from her academy. Monika discovers that Jordan was collecting evidence of Galgad's inhumane experiments, but he and Mattel are arrested by Galgad counterintelligence agents. Monika considers leaving the family to their fate, but recalling her friends in Lamplight spurs her to rescue Jordan and Mattel and help them defect to the Din Republic, with Mattel wishing to be spy like Monika.

During the date, all of the Lamplight quietly watch over Sara, but after it appears that Dominic has genuine feelings for Sara, most of them lose interest and leave.

In truth, Dominic is actually a con artist by the name of Tarik Pupke who specializes in romance scams, and he was planning to steal Sara's dog to resell to a rich buyer. With all of Lamplight is angered, Thea takes the lead to bring Tarik to justice. With Thea's help, Sara is able to turn the tables and seduce Tarik instead, convincing him to admit his crimes. Afterwards, Klaus offers to take Sara on a date to encourage her desire for romance. Thea confides to Monika that she washed out of her academy because she was too skilled at seduction and had too many improper relationships with the school staff, all in an effort to emulate Hearth. Later that night, Monika asks Klaus why Thea's seduction attempts don't work on him, and he explains that Thea needs to make eye contact with her target for her ability to work, which he has been avoiding all this time.

| Listening to Klaus' request, C assigns Lamplight a relatively simple mission to investigate a local restaurant where Galgad agents are suspected of using it as a front to deal drugs. Klaus assigns the mission to Annette due to her request to earn some extra money for a project she's working on. While the rest of Lamplight are skeptical that the normally chaotic Annette is capable of focusing on the mission, they are shocked at how competent she is posing as a waitress. Sara explains that Annette is actually very talented and adaptable, but only displays it when she's motivated enough. Eventually, Lamplight discovers that the drug ring is using bathroom graffiti as a system to deal cannabis. They apprehend the waiter running the ring, but have no leads on the real mastermind. Later that night, Annette ambushes a customer who had harassed her in the restaurant earlier, who coincidentally happens to be the spy masterminding the drug ring. Klaus apprehends the spy and chastises Annette that eliminating problem customers isn't part of a waitress' duties. The next day, Klaus receives a new mission from C. He then informs Lamplight that he will be taking the entire team with him to the United States of Mouzaia to track down Serpent. |||||||

White Spider explains that the Tolfa Economic Conference will begin soon, which will attract spies from all over the world, and orders Purple Ant to eliminate them all, including Klaus. Meanwhile, Klaus assigns Thea to lead the mission, but she remains self conscious about her failures to deal with Corpse and Matilda. After Klaus and Thea visit Corpse at a secret prison, Klaus realizes that Annette has sabotaged their car in an effort to get him to admit defeat. Klaus if forced to ditch the car where he is ambushed by Lamplight, but he is narrowly able to win due to calling the police ahead of time, forcing Lamplight to flee. However, Klaus is impressed with their growth and tells them their next mission will also double as their graduation exam. Realizing Lamplight was able to pull off such an ambitious plan without her involvement, Thea grows even more self conscious. Klaus and Lamplight then arrive in the United States and quickly infiltrate various areas of Mitouza to gather intelligence, though they also learn that foreign spies are being killed. It is also revealed that they had brought Corpse with them as their prisoner in order to identify Serpent. Part II: Lamplight continues their intelligence gathering, though Klaus warns that numerous foreign spies have been killed so far. Grete's main worry is that since Lamplight's training is focused on attacking Klaus, they have a lot of experience being on the offensive but little training to defend themselves against enemy spies. During the night, a politician's chauffeur named Barron attempts to drug Sibylla, but she thwarts the attempt and chases Barron into an abandoned building, which turns out to be a trap. Fortunately, Erna arrives to assist Sibylla against Barron. Meanwhile, Lily is framed for a murder and the police attempt to arrest her, and she is rescued by the intervention of Annette. Monika is lured into a high stakes game of darts by a woman named Miranda, and is narrowly able to defeat her by deflecting her dart. However, instead of giving any information, Miranda stabs herself in the neck with a dart. In a flashback, Purple Ant boasts to a wounded spy that he has filled Mitario with his "Worker Ants", regular citizens who he has brainwashed into his own army of sleeper agents. Part III: Monika manages to thwart Miranda's suicide attempt by knocking her unconscious. Meanwhile, Sibylla and Erna are able to defeat Barron, but upon learning that Barron was coerced by Purple Ant under threats to his family, Sibylla prevents him from letting himself bleed to death. However, despite their successes, Lamplight are ambushed by additional assassins. In the flashback, Purple Ant boasts to Hearth that he has hundreds of expendable Worker Ants in Mitario that he can use to overwhelm enemy spies, and then shoots her in the femoral artery. In the present, Grete heads out to support the others, leaving Thea to wonder how she can help in the situation. Annette then informs Thea of a rumor of a black haired woman assuring the Worker Ants a hero will save them, and Lily suggests Thea take advantage of that. Thea then confronts Corpse, who offers to help her since unlike the other Worker Ants, he didn't commit suicide. Thea frees Corpse, who immediately attacks and captures her before turning her over to Purple Ant. Part IV: Purple Ant boasts to Thea that he killed Hearth six months ago after she was betrayed by Guido, though Hearth promised that Klaus and Thea would return to avenge her. However, Thea reveals that she figured out Hearth's plan, so she mimicked Hearth's voice to break Corpse's brainwashing and turn him to her side, and had him capture her a ruse to lure Purple Ant into the open. Klaus then arrives to back up Thea and Purple Ant flees. After being cornered, Purple assembles his most elite operatives, the General Ants. Corpse and the rest of Lamplight then arrive to even the odds, and a all out battle breaks out. Corpse sacrifices himself to protect Thea, while Klaus reveals he has learned all of the skills Lamplight demonstrated trying to attack him, easily defeating the General Ants and capturing Purple Ant. Lamplight leaves the United States after making an agreement with the US government to cover up Purple Ant's murders by pinning them on Lily's cover identity. Thea then mentions to Klaus that Hearth promised to give her a present if they ever met again, and he shows her a secret compartment in Hearth's room containing and key and a message congratulating Thea. Thea then cries in Klaus' chest, finally feeling relief that she was able to live up to Hearth's expectations. |||||||

| Thea manages to find the box Hearth's key unlocks, but only finds an incomplete note inside it. Curious how Klaus knew to recruit her into Lamplight, Thea tries to reconstruct the note by writing numerous variations, including one that says "Klaus loves you." However, she accidentally drops the note in Lily's room. Lily discovers the note and gets flustered, and through a series of misunderstandings the note is spread around the mansion, leading Erna, Monika, Sibylla, and Sara to believe the note is directed at them instead. Klaus then announces he will need one partner to accompany him on his next mission, causing the girls to compete for the position. Meanwhile, Grete assists Thea with deciphering Hearth's note, and with some information provided by Olivia, Grete deduces it really says "Klaus saved you." At the time Thea was rescued by Hearth as a child, Hearth had already arranged for Klaus to train her as a spy to help her deal with her trauma. Upon returning, Thea clears up the misunderstanding about the note with the others, but she admits the whole situation lightened her mood. Klaus quietly observes and concludes that making Lily the team leader was the right choice, due to her ability to make others smile. Afterwards, Klaus congratulates Lamplight for officially graduating, and informs them they will focus on defeating Serpent, who appear to have gone rogue to pursue their own goals apart from Galgad's. |||||||
