Under the questionable tutelage of Klaus, the greatest spy in the world, the girls of Lamplight have been steadily honing their skills in preparation for their impending mission. But there's a more pressing issue at hand-just why were these specific members chosen for this team? Perhaps it's time to use their feminine wiles to pry the answer from their stoic teacher...

After the mission to take down Corpse, the next thing the girls have to contend with is a woman who has lost all knowledge of her past-Annette's mother. Although the emotional reunion initially brings everyone together, a cruel twist of fate will soon send fissures through the team...

Klaus reveals he is married to a member of Lamplight, but the identity of the bride remains unknown. And so a battle ensues among the girls to determine who it is. Gain a peek into the girls' daily lives in this collection of short stories!

The golden age of the military has passed, and war is now carried out by spies. Klaus, an agent with a perfect record but a difficult personality, has formed a special team to carry out an "impossible" mission with a 90% failure rate. Problem is...the ones he's chosen are a bunch of pretty girls with no experience!?

Lamplight infiltrates the Fend Commonwealth in search of answers about the deaths of some of their fellow spies. But as Sybilla pushes herself to complete the investigation, she meets unexpected resistance from the leader of Belias, a powerful counterintelligence organization. Can Lamplight avenge their fallen countrymen?

When a sickly boy succumbs to illness only to reawaken as a weakly undead, his first thought is not of horror, but joy. Sadly, his delight is cut short by the realization that he is still not in control of his own body. The excruciating pain that plagued him in his previous life has simply been replaced by the necromancer that brought him into this one. Now, to win true freedom, he must put his unlife on the line and fight for his dark master...!

As old charades end and new ones begin, the intricate system of secrets and lies holding the Alliance together threatens to collapse like a house of cards-not that Akiteru's noticed. He's been a bit preoccupied with Iroha, who he can't help seeing in a new light. It would figure, then, that his uncle would pick now to show up. So long as he's around, Akiteru's going to have to work double-time to sell the angle that he and Mashiro are a real fake couple. Dealt this bum hand by fate, can Aki come up with the perfect bluff, or will he fold? Can any gambit survive intact while Iroha's a player? And when the summer festival finally comes, just who will Akiteru wind up watching the fireworks with?

Klaus finally has a lead on the Empire's mysterious spy team Serpent. Determined to expose their identity, team Lamplight sets off in search of the serpent's nest. However, what awaits them at their destination is beyond anything they could have imagined...

The culture festival’s over, and it’s finally time for some rest and relaxation! Well, it WOULD be if Akiteru weren’t wrapped up in various interrogations. Mashiro and Iroha’s mothers team up on him, eager to suss out his intentions. Which of their daughters is he after? Both? Neither? Meanwhile, Akiteru’s gotta figure out what’s going on between his aunt and uncle. Can he get himself out of this one, or does even more disaster await?

It’s time for the biggest event of any high school career: the class trip! With Iroha out of the way, Mashiro’s more determined than ever to deepen her (fake) relationship with Akiteru. Sucks for Mashiro, though—a third girl is now vying for Akiteru’s affection! And Iroha’s launched into a long-distance offensive to pester him, but will that be enough for her? With so much trouble brewing, this “relaxing” trip to the hot springs will be anything but!

Mashiro has just shared a devastating secret with Sumire. Aki and Iroha have been forced through a ceremony that historically guarantees the participants will be married. Meanwhile, Sumire is on the brink of freedom-but just what will she do with it? So much for Aki's efficient summer plans! Worse, he finds out the foundations beneath his Alliance are pillars of salt and sand. With the Alliance pulled in all directions, will it even last the summer, or will it sink into the depths of the ocean?

If a girl teases you, that means she likes you!Unfortunately, Akiteru knows from experience that isn't the case. Because every girl he interacts with shows him nothing but scorn, and he's not scored a single date from it! Luckily, he's more concerned with securing a spot for him and his game-development buddies at his uncle's business.But when his uncle throws him a condition that involves playing the part of his daughter's boyfriend, Akiteru has no choice but to take it. What will his best friend's sister Iroha, who bullies him relentlessly, think of the news?

Thanks to Midori’s confession, Akiteru’s finally ready to work out his feelings! Too bad he’s still in the middle of a class trip! Mashiro goes on the offense and invites Akiteru on a date to a theme park, and Iroha’s mother greets them with open arms... But why the heck is Iroha there too? Akiteru just wants to catch a break for once! Aren’t theme parks supposed to be fun?!

The Impossible Mission begins at last! Codenames Flower Garden, Pandemonium, Daughter Dearest, Dreamspeaker, Glint, Meadow, Forgetter, and Fool all have their own goals, and each is prepared to work from the shadows to see it done. Can they come together and succeed, or have they been set up to fail?

The girls of Lamplight may have all washed out of their training at the spy academies, but under their leader, Klaus, they've managed to take on Impossible missions with resounding success. However, now another spy organization, one consisting of the best of the best from the academies, is in need of a leader--and they've got their sights set on Klaus. Is this the end for Lamplight?!
