[[caption-width-right:315:Let's just say it's complicated.]]

A manga by Aimoto Shou that ran in Weekly Shounen Jump from 2009-2011. The story revolved around Hadesu Itsuhito, a school nurse with a unique power to get rid of "disease demons" - mysterious, emotional-based creatures that take control of their host in different ways. [[spoiler:Hadesu-sensei's power comes from perpetually being infested by one of those creatures.]]

The series started off using a MonsterOfTheWeek format, with mini arcs sprinkled in between, and finally brings in a BigBad and a QuirkyMiniBossSquad.

Now complete [[Characters/HokenshitsuNoShinigami with a Character Page]].


----
!!Provides Examples Of:

* ActionGirl: Kaburagi
* {{Adorkable}}: Keiichi and Hadesu-sensei
* AmbiguouslyBrown: Keiichi
* {{Animal Eyes}}: Niburu has snake-like pupils.
* BadassTeacher: Obviously Hadesu-sensei. Also Mitogawa.
* BerserkButton: Threatening people in front of Hadesu is not a good idea.
* BigFancyHouse: Fuji lives in one.
* {{Bishounen}}: Fuji is canonically the handsomest kid in school.
** [[spoiler: Hadesu also fits this trope when his hair is black]]
* BlackmailIsSuchAnUglyWord: The president of the School Newspaper tries to blackmail [[{{Bishonen}} Fuji]], [[{{Delinquents}} Senoo]] and [[ActionGirl Kaburagi]].
* BreakingTheFourthWall: In chapter 29, when Fuji asks Hades what happened, he says that they're 'out of pages this week'.
** In the next chapter, Ashitaba can be seen covering up curse words in the text bubbles of other characters.
* {{Catchphrase}}: Hades-sensei's "assimilation complete".
* ClassTrip:
* {{Delinquents}}: Senoo
* DemonicPossession: Sort of the premise of the series.
* DrivenToSuicide: [[spoiler:One of the side characters committed suicide, and her mother refused to accept it, leading to a rather nasty disease demon gaining control...]]
* {{Ecchi}}: The series veers off in this direction sometimes.
* ElegantGothicLolita: Mitogawa dresses like she just stepped out of the Victorian era everyday.
* EyesAlwaysShut: Fuji's older brother Sanzou keeps them closed most of the time and only opens them in surprise/to bitch out Fuji.
* FanService: The author tends to insert some fanservice in more humor-based chapters.
* TheFaceless: [[spoiler: Mitogawa]] in the early chapters.
* FreakyFridayFlip: There was a disease demon that caused this in one chapter.
* GroundhogDayLoop: The disease demon would rewind a specific period of time until its host "perfected its rehearsal".
* HealingFactor: Subverted. In chapter 31 [[spoiler:it is mentioned that Hadesu can't use his dominant arm for a while as a result of the wound he sustained to his shoulder in an earlier chapter.]]
* HeManWomanHater: Senoo. He's better about it now, though.
* HostageSituation:
* LethalChef: The kids mistake Kaburagi's chocolate for coal.f
* LiteralSplitPersonality: One disease demon's effect; in this context the victim's emotions are split and driven out while the victim's real self is put to sleep. This poses a problem for Hadesu-sensei when [[spoiler:Fuji]] contracts it, because [[spoiler:he can't immediately use his power to help while Fuji's real self is empty and devoid of emotion]].
* LoveLetterLunacy: Played with during the Valentine's Arc. Fuji's desk was buried beneath the chocolate and flowers.
* MonsterOfTheWeek: Starts off as this until the final arc.
* MysteriousPast: So, how did Hadesu-sensei come to possess a disease demon?
* NotWhatItLooksLike: Most interactions between Hadesu-sensei and Saizaki-sensei center around this.
* OlderThanTheyLook: Mitogawa-sensei.
** Hadesu remarks in a chapter that 'her appearance hasn't changed at all for the past ten-odd years'. He seems find this perfectly acceptable and just says that 'women are really unbelievable'.
* OnsenEpisode: Not quite an onsen, but it was a bath scene, complete with a peeker.
** Oh, and did this troper mention that there was a SkinshipGrope going on above the peeker's head where he couldn't see?
*** Don't forget that [[ModestyTowel modesty towels]] were gone by the end of the chapter!
* OrdinaryHighSchoolStudent: Actually middle school students.
* {{Otaku}}: Yasuda would do anything for his idol love, Atsuko.
* SchoolNewspaperNewshound: Yamada and Yodobashi have a tendency to bend the truth a little.
* PaintingTheMedium: During Mimasaka's encounter with [[spoiler:[[ItMakesSenseInContext Melancholy Rousuke]]]] in chapter 27, the latter decides that using kanji while talking is annoying and asks if it's all right to speak only in hiragana from then on. He does it anyways, and his text switches to all-hiragana. (In English, it'd be visually similar to squishingtheletters together, like so.)
* PuppeteerParasite: A lot of the disease demons are like this.
* SchoolNurse: Hadesu-sensei is an uncommon male example.
* {{Ship Tease}}: In chapter 53, we got Kishibe Kagerou [[spoiler: whom look A LOT like black-haired Hadesu]] crushing hard on his childhood friend, Midori [[spoiler: whom just look like mini-Saizaki]]
* ShoutOut: Several-
** Mother3 [[http://www.mangafox.com/manga/hokenshitsu_no_shinigami/v02/c019/13.html anyone?]]
** Do the words StreetFighter remind [[http://www.mangafox.com/manga/hokenshitsu_no_shinigami/v02/c011/5.html you of anything?]]
* ShrinkingViolet: Hanamaki.
* SnowballFight: Suberted. Mimisaka tried - however the arrival of a certain something had him and everyone else fleeing for their lives...
** Skiing for their lives, more like it.
* StrangelyEffectiveDisguise Hadesu and Mitogawa promoting a pachinko parlor. Surprisingly, no one said anything.
* TeacherStudentRomance: Kaburagi's (thankfully unrequited) crush on Hadesu-sensei.
* TheSlacker: Fuji makes it his mission in life to put in as little effort as possible.
* {{Tomboy}}: Kaburagi. Predominantly as a child but she still has tendencies.

* {{Tsundere}}: Saizaki-sensei
* WeirdnessCensor: Averted with everyone panicking over the white hair of Hades, and realizing something is going on whenever a disease demon strikes.
* WhoYouGonnaCall: Hadesu is often called upon by students and the principal to solve problems. Justified in the fact he's one of the few people who can handle it, and he was hired for that reason.
* {{Yandere}}: Motoyoshi
