The tail of a boy, a kitsune… and a maid? Kevin Swift doesn’t know what to think anymore. His love for Lindsay has dwindled, his mind is constantly plagued by thoughts of Lilian, and now he has to deal with his sexy housemate’s maid: A kimono-clad, katana-wielding femme fatale who doesn't like him very much—and who has this weird tendency of adding Japanese suffixes to everyone’s name for some reason. Go figure. Now Kevin must make an irreversible choice: To become Lilian’s mate or not. It’s a life changing decision that no teenager should have to make. Unfortunately for him, Lilian’s maid has basically threatened to clean out his entrails with her katana if he doesn't. He used to think being a teenager sucked. Now he’s realized that being a teenager is nothing compared to being the potential mate to a kitsune whose maid holds no moral compunctions about flaying him alive.

The fan service continues… Life has finally settled down for Kevin Swift. Sure he’s still dealing with Lilian’s zany antics, but that’s alright, he’s actually starting to enjoy the gorgeous Kitsune’s continued presence. Too bad he's in denial. Unfortunately for him, life likes to throw fastballs when you least expect it to, and his life is about to get ecchi―I-I mean, ugly. A tsundere dressed in gothic lolita fashion… A boy whose hair is bigger than his brain… A new enemy that makes Chris Fleischer look like a fifty pound weakling… Trying to admit his feelings for a certain tomboy… Not to mention Lilian herself. Yeah, Kevin’s got problems, and life can only get more strenuous from here on out. Oh, well. At least he hasn't been turned into a Harem Protagonist.

THE FAN SERVICE CONTINUES… Two weeks have passed since Kevin Swift was kidnapped by spandex-clad secret agents, rescued by Lilian, and they were both subsequently saved by Lilian’s faithful maid-slash-bodyguard. Since then, Kevin has nabbed himself a foxy girlfriend—pun very much intended—and a person willing to train him in the arts of badassery. Needless to say, life has been good. Then Lilian's family decided to pay a visit. And everything went to hell. Sometimes, life gives you lemons. Other times… well, you get the picture.

The story of a boy, a fox, and a whole lot of ecchi... Kevin Swift has the worst luck with women. It's not that he's unattractive or even unpopular. He just can't talk to them. He blames it on all those Shōnen love comedies he enjoys watching. Fortunately, or unfortunately―depending on who's asking―Kevin's love life is about to start looking up. After saving a fox's life Kevin discovers that he actually rescued a Kitsune, a shape-shifter capable of transforming into a beautiful girl who appears to have popped right out of the pages to a Shōnen manga. Her name is Lilian, and she apparently wants to mate with him. Between dealing with an overly amorous vixen's zealous attempts at getting into his pants, his inability to talk to girls and school, Kevin is going to have his hands full.

THE WAR HAS BEGUN… Four months have passed since the war between humans and yokai began, and there seems to be no end in sight. Kevin and Lilian have been doing what they can to help, but since they’re also attending high school, taking part in a war is somewhat difficult. It’s a good thing Kevin’s boss has concocted a plan in which he and Lilian are essential. Kevin, Lilian, and Iris must travel to Los Angeles, California, and request the aid of Kuroneko, a member of the Four Saints. But wherever these three roam, trouble is sure to follow—and this time, it will take more than shonen manga antics to escape from the many dangerous and dangerously erotic situations they’re bound to run into.

The PLOT thickens! Kevin Swift returns home with Orin in tow. The last member of the Four Saints has also made a surprise appearance! Yet even with the Four Saints back together, there are still numerous problems that look insurmountable. The war between humans and yokai has become even more violent, assassins and dangerous plots threaten to tear the world apart, and Kevin lost his homework. While he can deal with the first two issues, that last one is causing him a whole slew problems. The troubles of a not-so-ordinary high schooler are never ending.

A Tail of Fan Service! Kevin Swift has faced many problems since becoming Lilian’s mate: bullies, the older sister of bullies, the older sister’s jabronis, bratty kitsune, yōkai assassins, anti-yōkai militant groups, tentacle monsters, and the mightiest Celestial Kitsune in the entire world. He’s survived through it all, growing stronger and more mature in the process—at least, he likes to think so. But another problem is about to descend upon him, one that will affect far more than just him. The Sons and Daughters of Humanity are making their move, and neither Kevin nor his family are in any way prepared for the coming storm.

Not All Fun in Tropes... Kevin Swift's life is strange, unusual, and downright zany. Then again, what else should he expect when he's mated to a kitsune? Despite the oddness encompassing his life, he wouldn't change it for the world. Unfortunately, sometimes the world doesn't let people decide these things. When he, Lilian, and his friends are attacked by the Shénshèng Clan, Kevin learns that a war has broken out between clans Pnevma and Shénshèng, one that threatens the lives of himself and the people he loves. He and his mate's family are taken to the Pnevma Clan estate in Greece. Yet even the protection offered by the most powerful spirit clan in the entire world may not be enough to keep them safe.

THE WAR CONTINUES... Kevin, Lilian and Iris have reunited with Christine, yet several major hurdles keep this reunion from being truly heartwarming—though it certainly hasn’t stopped things between Kevin and the girls from heating up. Christine introduces them to Orin, an ornery and perverted old monkey with a thing for flat chests, who has no intention of joining Daven Monstrang’s alliance. Dark truths are revealed, enemies show their fangs, and Kevin still has to convince Orin to ally himself with Daven Monstrang and Kuroneko. But in order to convince Orin to join their alliance, Kevin, Lilian, and Iris will have to prove themselves by confronting a threat none of them are prepared for.

Not Exactly a Triumphant Return Home. Kevin and Lilian, along with their family and friends, return home after their disastrous spring break vacation. Kevin tries to come to terms with the not-so-shocking knowledge that the yōkai world isn’t all humor and tropes. While Kevin is dealing with this newfound knowledge and the loss of his innocence, life returns to normal—what passes for normality when living with a family of kitsune. But when lightning strikes, it likes to strike twice. Too bad for Kevin, the world of yōkai is the same way. He and Lilian will soon learn that the yōkai world isn’t prepared to let them go just because they want to live the life of normal high school students.
