!!!Tropes associated with Yugen Kaisha:

* AccidentalPervert: Karino, in Incident File 03: Love Me Tender, when he walks in on Mr. Nagasuki and his secretary [[InterruptedIntimacy while they're getting it on in his office!]]
-->'''[[SexyDiscretionShot *secretary screams from off camera*]]'''
-->'''Nagasuki:''' "Get the hell out of here!"
-->'''Karino: (closes door, snickering)''' "Hot action."
* ActionGirl: Ayaka. She hunts down spooks and demons, then takes 'em out. Or she has Rokkon excorcise them.
* AssholeVictim: Mr. Nagasuki. He doesn't die, but close enough.
* ATeamFiring: gets lampshaded during Incident File 02: "End of the World" after Karino empties half a clip without hitting the evil doctor, who's less than ten feet away!
-->'''Ayaka: (incredulous)''' "Where the hell'd you learn how to shoot?!"
-->'''Karino: (shrugs sheepishly)''' "At the academy!"
* BaldOfEvil: [[spoiler: The Hadja]], a monk group who challenges Phantom Quest in the fourth episode; their leader, [[spoiler: Mukyo]], in particular.
* [[BarrierWarrior Barrier Monk]]: Rokkon, Phantom Quest's staff exorcist.
* BewareOfHitchhikingGhosts: Narita.
* [[HardDrinkingPartyGirl Bottle Fairy]]: Ayaka. Big time. She's known for getting plastered and punching out cab drivers. Or just getting plastered period. The intro even shows Karino carrying her home while she's drunk, and in case file 01, [[OurVampiresAreDifferent Bosco]] refused to take her blood, due to the alcohol content!
* BreakingAndBloodsucking: Dracula initially preys on Makiko whenever she steps out at night. But, after repeat interference from Ayaka and Bosco, he goes straight to her bedroom. However Karino, and Ayaka's timely arrival, causes him to flee with Makiko, to TokyoTower.
* BrokeEpisode: The members of Phantom Quest end up part timing just to get by, during incident file 04, thanks to [[spoiler: the Hadja]] stealing all of their clients.
* ByThePowerOfGreyskull: "Red dragon spirit, capture Star Sword."
* CharlesAtlasSuperpower: Rokkon who, in the fourth incident file, leaps from the third floor of the Hadja's temple, while carrying Karino and Nanami and lands, without injury.
* ChildrenRaiseYou: {{Parodied}}. Ayaka's sorta responisible, but her recklessness often lands Phantom Quest deep in the red. It doesn't take long to see that it's Mamoru's management skills that keeps the company afloat. Not to mention all the times he has to chastise her for getting drunk, and over sleeping.
* ChristmasCake: Ayaka sometimes asks Madam Sumei if there's any hope for her love life only to be told her chances of finding happiness are zero. Doesn't help that she gets called an "old lady" by a cafe full of young teen/twenty-something females either.
* CovertPervert: Karino again, in the final episode, where he gets [[MaleGaze an eyefull]] when Ayaka loses her top; which earns him a MegatonPunch.
* DeadlyDoctor - The demonically possessed doctor from Incident File 02: End of World.
* [[DeclarationOfProtection Declaration of Protection]]: Bosco and Narita toward Makiko and Natsuki respectively.
** In the first Incident File, it first appears that Bosco is stalking Makiko. It's eventually revealed that he was protecting her from another vampire, who had recently reincarnated.
** In Incident File 03, Narita keeps his girlfriend safe from Nagasuki's advances, and takes it upon himself to set up the exhibit for her, after Nagasuki pulls the night crew... and does it all from the afterlife!
* DestructiveSaviour -Ayaka, and she has the bills to show for it too.
* DistressedDude: Karino fills this slot during the fourth episode, "Lover Come Back to Me".
* DoggedNiceGuy: Karino tries in subtle ways to impress Ayaka and prove she can depend on him, such as incident file 03, where he attempts to tail Nagasuki, thinking Ayaka would be proud of him. Sadly, he blows a tire and gets left by the side of the road. Earlier, he attempts to surprise her with a box of pastries, but drops it on the way. Needless to say, Ayaka was not impressed.
* [[FedToTheBeast Fed to the Ghosts]]: [[spoiler: Mukyo]] threatens to do this to Karino, after he's caught investigating his scam operation, by dangling him over a pit filled with all the apparitions [[spoiler: the Hadja]] allegedly excorcised.
* FieryRedhead: Ayaka's not-so-bad, most of the time, but she's known for her rash behavior and having a hair trigger temper.
* HeavySleeper: Ayaka Kisaragi.
* HerHeartWillGoOn: Natsuki by the end of Incident file 03: Love Me Tender.
* HeroicBSOD: Nanami has one near the climax of the final case file, when she, Rokkon, and Karino find themselves surrounded and vastly outnumbered by ghosts. She becomes so frightened that her mind goes blank, complete with [[WingDingEyes spiral eyes]]; making it a rare [[PlayedForLaughs comedic version]] of the trope.
* HeyItsThatVoice: Plenty in both the original Japanese and the English dub, RicaMatsumoto is Ayaka, KazueIkura is Mamoru, KoichiYamadera is Kozo Karino, Creator/AyaHisakawa is Natsuki Ogawa, and KotonoMitsuishi is Nanami, On the English side, WendeeLee is Ayaka, BrianneSiddall is Mamoru and MelissaFahn is Nanami.
* ImprobableWeaponUser: Ayaka's lipstick becomes a friggin' [[LaserBlade light sabre!]] It even makes the same sound effect when activated.
* InterspeciesRomance: Makiko and [[OurVampiresAreDifferent Bosco]], by the end of the first episode.
* ISeeDeadPeople: Just about everybody in the series, though it's mainly Phantom Quest. It's all part of the job.
* KickTheDog: Mr. Nagasuki does this repeatedly to Natsuki in his efforts to get her into bed. First by coming onto her, then pulling the night crew from the exhibit when she rejects his advances. He finally threatens to cut off the exhibit's funding unless she [[SexualExtortion "co-operates".]] Thankfully, she had Phantom Quest to protect her [[spoiler: and Narita.]]
* LeaveTheTwoLovebirdsAlone: Nanami invokes this at the end of the final episode by ushering Rokkon away when it appears that Ayaka's getting ready to [[RelationshipUpgrade confess her feelings]] to Karino; complete with HeldGaze and LuminescentBlush.
* LoveRedeems: A {{flashback}} reveals that Bosco repeatedly exposed himself to crosses, garlic, high powered UV lamps to build resistance [[RemovedAchillesHeel (eventually immunity)]] to sunlight, and even tried to give up blood [[spoiler: which he found he couldn't, so he limits himself to feeding only four times a year, while taking supplement tablets inbetween]], all so he could be with Makiko.
** The downside, however, is it's caused him to become anemic and lose much of the power he'd have, as a vampire, [[spoiler: if he fed regularly.]] Even so, he's perfectly content that way, [[YouAreWorthHell so long as he can be with her.]]
* MsFanservice: Ayaka's a redhead, has a stunning figure [[ChristmasCake for a woman her age]], routinely sleeps in the nude, and will often show up for breakfast, in her panties, with her top open. Oh, and [[ShesGotLegs she's got legs.]]
* NotAMorningPerson: Ayaka Kisaragi. See the [[HardDrinkingPartyGirl Bottle Fairy]] entry above.
* NotDistractedByTheSexy: Mamoru is completely unfazed by Ayaka's habit of sleeping in the nude, and shows neither interest or embarrassment when he enters her room to wake her up each morning; nor is he bothered by how she shows up for breakfast.
* OccultDetective: U Division's Detective Karino, who commisions jobs to Phantom Quest. Ayaka and Madam Sumei count as well.
* OurGhostsAreDifferent: Narita. The guy can cover the nightshift, in case your workmen bail on you, and can [[HardDrinkingPartyGirl knock 'em back like a pro]] when he's done.
* OurVampiresAreDifferent: Bosco is anemic [[spoiler: due to limiting himself to feeding only four times a year]], and runs a tea shop for pretty young twenty somethings. Plus, he's a NiceGuy!
* PermaStubble: Karino.
* PerpetualPoverty: While Phantom Quest always solves the case, they always end up in the red due to Ayaka's recklessness and spending habits.
* PlayingWithFire: Nanami's special ability. Too bad [[PowerIncontinence she has trouble controlling it]], especially when she's frightened.
** RedEyesTakeWarning: If you see flames ignite in her irises, [[OhCrap RUN.]]
* RemovedAchillesHeel: As seen in the LoveRedeems entry, Bosco eventually became immune to sunlight, garlic and crosses through controlled exposure to them.
* RicaMatsumoto: Ayaka's Japanese seiyu
* ShipTease: Ayaka with Karino, gets [[ShipSinking deep-sixed]] in the end though. [[MaybeEverAfter Or was it...?]]
* SoLongSuckers: Ayaka does this to Madam Sumei, when it comes time to pay for her services.
* TakingYouWithMe: Mukyo attempts this, after his defeat, by [[spoiler: grabbing Ayaka's leg then pitching himself off the roof with his dying breath. He ends up in a tree. Ayaka, however, ends up [[ShipTease in Karino's arms]] when he breaks her fall by catching her.]]
* UnresolvedSexualTension: Between Ayaka and Detective Karino, with shades of BelligerentSexualTension.
* WendeeLee: Ayaka's English dub voice.
* WillTheyOrWontThey: Played with over the course of the series. It almost happens at the end of the final episode... then Karino mucks it up. See the CovertPervert entry above.
