''Mika-sensei, what are you doing getting stuck in the middle of all the first-years?''

'''''Doki Doki School Hours''''' (known as ''Sensei no Ojikan'' in Japan) is a manga by Tamami Momose, depicting the adventures of 27-year old Suzuki Mika, homeroom teacher of class 2A of Okitsu High School. Because of her diminutive size she often feels overwhelmed by the antics of her students. They form quite an [[WackyHomeroom eccentric bunch]]: we have our fashion-victim, an [[{{Otaku}} otaku]], a [[SchoolgirlLesbians lesbian student with a crush on her teacher]], a narcissistic crossdresser and a gay guy obsessing over a classmate who [[SelectiveObliviousness doesn't have a clue and only thinks of sports]].

To make things worse, Mika is often quite [[TheDitz ditzy]] herself, so she is not always on top of things. The fact that she still lives with her parents and is spoiled terribly by her father doesn't help much either. Still, the students love her and hold her in high esteem, so things manage to work out most of the time.

The anime series, produced by {{JC Staff}} and broadcast in 2004, starts out with typical high school fare, like festivals, sports events and the ever-dreaded "{{measuring day}}". Later on there is a change of pace, leading to a series of genre spoofs vaguely reminiscent of ''Anime/ExcelSaga'', only to have things become very serious again by the last episode. The mood and animation style are very loose and cartoonish and seems to have been influenced by ''Manga/AzumangaDaioh'' quite a bit, even though the manga it is based on actually pre-dates ''Azumanga Daioh'' by a few years. ''Doki Doki School Hours'' is highly recommended for viewers who love bizarre characters and dry humour interpersed with some genuinely touching moments.

* HighSchool

Then they all cling onto her thinking she's still leaving, only to find out Mika was just helping Matsumoto-sensei find a new apartment. The next day, things [[StatusQuoIsGod return to normal,]] with no one listening to her again.
* RelaxOVision: One instance is used when Suetake is describing how Nakamura got the nickname "old man" despite being 17 years old. It switches to a field of grass when he starts to pull his pants down. When the scene returns to the classroom, Mika-sensei tells Suetake such description doesn't belong in the public.
* SchoolgirlLesbians[=/=]HotForTeacher: Voluptuous Kitagawa has a crush on petite Mika, but it's mostly played for laughs.

* ShipTease: A fairly large proportion of the jokes involve someone expressing affection for someone else, with the other characters reacting "is this it?", and of course it's not ...
* SliceOfLife
* StatusQuoIsGod: In episode 20, Mika-sensei's mom tells her about her uncle setting up a [[ArrangedMarriage meeting with a man for marriage.]] The main characters in her class are [[HeroicBSOD hit pretty hard]] at the prospect that she may quit teaching as a result. [[spoiler:Then Mika-sensei shows up at the start of the new term, and explains to them that while the meeting took place, the groom's family felt a woman who couldn't clean or cook would be troublesome, so the marriage plans fell through. However, her class is thrilled to have her back, particularly Kitagawa, who vows never to let her go again.]]
* StraightGay: Kudo.
* SweetTooth: Kobayashi and especially Mika-sensei. Kitagawa will often bribe the latter with sweets, only to then put them out of reach to [[ItAmusedMe watch her reactions.]]
* TheOjou: Apparently Minako, given that her family home is huge.
* TeacherStudentRomance:
** Played with regarding Kitagawa and Mika-sensei. Its entirely one-sided on Kitagawa's part, and she often does things to get a reaction out of Mika-sensei because she finds her reactions [[ItAmusedMe so adorable.]]
** Nakayama fears Watabe is going to do this with the student-teacher Hori-sensei in episode 11. Its just her imagination running wild however.
* TeamShot
* TemptingFate: In episode 2, Mika-sensei says she won't bother learning basketball rules, since she's just the back up referee. Then the main referee catches a cold and has to stay home that day...
* TerribleArtist: Chinatsu Nakayama. In episode 6, she wishes to join the manga club since she's a fan of Watabe's manga, and hands him a sketchbook. As the other characters look on, the drawings displayed look like they were drawn by a 3 year old.

* ValentinesDayEpisode: Episode 8. As can be expected, things don't go exactly as planned for many of the characters, such as Kudo attempting to give Suetake a chocolate and say that its from him, rather than a random girl in their school. Or Kobayashi giving obligation chocolates to all the male characters, and expecting them to give her something on White Day. Which they all either forget, or get something really strange for her.
* VisibleSilence
* WackyHomeroom
* WeightWoe: Mika-sensei and Kobayashi suffer from this the most.
* WiseBeyondTheirYears[=/=]YoungerThanTheyLook: Gen, AKA "Oyaji", who looks and acts like he is in his forties despite being only seventeen.
