* BokeAndTsukkomiRoutine: Koizumi's relationship with Otani is mostly played as a Manzai comedy pair, which is why they are both seen as the {{Class Clown}}s by their peers (classmates and teachers included).

* DudeMagnet: Even if people don't usually look up to her for her beauty and her tomboyishness, she has her fans as Otani, Haruka, and Kohori are all attracted to her.

* DudeMagnet: Even if she's not that admired for her beauty and is often regarded as no girlfriend material due to her being not "conventionally cute" because of her height and tomboyishness, she has Otani, Haruka and Kohori being attracted to her.

* FourTemperamentEnsemble: [[FunPersonified Sanguine]] and a dash of [[FieryRedhead Choleric]].

* HugeSchoolGirl: Basically, half the premise is based on she being a girl more taller than the Japanese average.

* IronicName: Her last name is Koizumi and means "little spring" in Japanese, and she is taller than any other girl in her school. This is [[LampshadeHanging lampshaded]] in the first scene.

Otani gets unwillingly jealous of Maity, and finally realizes about his feelings for Risa in a GreenEyedEpiphany.

By the end of the series he follows his dream to become an [[spoiler: elementary school teacher]],[[FriendToAllChildren stating he has always liked kids to the point in having some 10-years old as his basketball friends.]]

* AwLookTheyReallyDoLoveEachOther: Often has these moments with Koizumi.

* BelligerentSexualTension: With Koizumi. They start very much like this, but it's somewhat unusual in that it's entirely viewed from the [[{{Tsundere}} Tsundere's]] perspective.
** Although Otani has his times like a JerkWithAHeartOfGold

** If Risa starts showing feelings for another guy. This guy is [[CrazyJealousGuy really, really jealous...]] but given what happened with his ex–girlfriend [[BrokenBird you can't blame him]].

* BokeAndTsukkomiRoutine: At first he was the [[BokeAndTsukkomiRoutine Boke]] to Koizumi's Tsukkomi. After the RelationshipUpgrade he acts more like the [[BokeAndTsukkomiRoutine Tsukkomi]] giving at Koizumi [[DopeSlap Dope Slaps]] often.

* ChickMagnet: He is very popular with the girls, even though he has an [[AllGirlsWantBadBoys attitude problem]] and if his height gets out of the question. Girls like Kanzaki, Mimi, Risa, and Seiko have fallen for him. Maybe because many of them see him as "cute".

-->'''Risa''': ...Why should you be annoyed?
-->'''Otani''': How should I know? Annoying things will, of course, annoy me!! Don't ever mention his name again!!
** Purposefully invoked by Maity-sensei via his "magic" in order to make Risa happy.
* GreenEyedMonster: He easily gets jealous (such as when Maity offered Risa to take her home) even though, deep down, he knows he doesn't have to worry since Risa is always going to be in love with him.
** He became insanely jealous when he saw Risa with Kohori. He even told Risa that he'd punch Kohori in the face if Risa was with him again.
** Oh, and let's not forget the chapter from the manga's volume 12 where Risa had to model with Mimi (and as a result, [[SheCleansUpNicely ended up getting absolutely dolled up]]) and some guys comment on how they find her cute and one of them implies that he wants to make a move on her. He's not amused by their comments and even makes an "angry beast" face at them to scare them off!

* HasAType: Otani likes short, cute, and helpless girls, and he seems to think that they need to be feminine and a bit shy. [[TrueLoveIsExceptional Ironically, he ends up falling in love with a]] [[{{Tsundere}} temperamental]] HugeSchoolGirl, who isn't seen as ''very'' feminine by her peers.
* HeroesWantRedheads: Although Otani didn't fall for her at first, Koizumi is definitely a FieryRedhead, just like him.

-->'''Otani''': [[DopeSlap *smack*]] '''DON'T YOU GET INVOLVED TOO!'''
-->'''Risa''': ACK!
-->'''Nakano-Sensei''': [[VisibleSigh ''Aah...'']] We don't have any time left so we'll just let the married couple class representatives be the committee.

* TheMatchmaker: He was trying to hook up Koizumi with Suzuki, instead, he ends up developing a MatchmakerCrush on her.

[[folder:Supporting Cast]]

Mimi is a [[PatientChildhoodLoveInterest friend from Otani's childhood]], who is a "[[{{Kawaiiko}} very cute]]" girl who works as a model. However, Mimi is actually the opposite of what she claims to be, as she is very egotistical, very jealous, and is a little [[{{yandere}} possessive]]. At first glance, Mimi is the Betty, but when her true personality is revealed, she is the Veronica.

-->'''Risa''': [Risa sneezes]
-->'''Otani''': Don't sneeze like an old man!

* ObliviousToLove: Not only is he initially completely oblivious to Koizumi being head over heels in love with him, even writing off an outright declaration of love from her as a joke.

* OlderThanTheyLook: Since he is shorter than the average Japanese guy, he is mostly confused as a kid by many people.

* {{Tsundere}}: A rare male example of Type A with heavy emphasis on the "tsun" part. Otani is often showing the “tought” kind of love, rarely expressing directly his feelings for Risa. [[InsultOfEndearment His pet name for her could be considered “idiot” or “stupid” since he always calls her that way]] even when [[LuminescentBlush blushing.]]
** Even moreso than Koizumi. In fact she is way more open with her feelings and tries to be a cuter girlfriend just for him, but this hardly works cause he never appreciates it or he say things like “gross” or “weird” when she tries…
** [[BerserkButton …And that just pulls her tsundere side off her.]]

Risa is seen as [[FieryRedhead impulsive and strong-willed, rarely willing to display her softer side.]] She is a {{tsundere}}. She is also very [[CuteClumsyGirl clumsy]] and apparently talks a lot, usually in not such a good way.

It is strongly stated by the other characters that she is very funny for a girl and a fun person to hang out with. At the same time, she also implies [[{{Tomboy}} she is not cute and girly]], the type of girls that are very appreciated in Japan, possibly due to her tall stature. Her favorite artist is Umibozu, her admiration for him going to the point of obsession.

* CuteClumsyGirl: She falls quite often, like when she’s going at the Umibouzu’s concert. Although she seems to be more serious harmed.

* DoggedNiceGirl: She becomes this when she realizes her crush on the lead male Atsushi. It doesn't help that all of her friends, usually [[ShipperOnDeck Nobuko and Nakao]],are constantly encouraging her on in her pursuit of him.

* DudeMagnet: Even if she's not that admired for her (existent) beauty and is often regarded as no girlfriend material due to her being not "conventionally cute" because of her height and tomboyishness, she has Otani, Haruka and Kohori being attracted to her. Also, in the chapter where [[SheCleansUpNicely She Cleans Up Nicely]], two guys talk about how they find her cute and one of them implies he wants to make a move on her after the photoshoot before Otani [[CrazyJealousGuy scares them off]].

** Although is unintentionally, and usually PlayedForLaughs.

** [[LampshadeHanging Lampshades]] for Otani when she points at him saying his no going to win the bet that they made.

* HugeSchoolGirl: Basically, half the premise is based on she being a girl more taller than japanese average. ''And she is very insecure about it''.
* InsecureLoveInterest: To Otani. She thinks very high of Otani's ex-girlfriend, Kanzaki, wondering why would he pick her over his ex-girlfriend.
** This is partly because his hard and cold behavior around her and his inability to tell what he feel for her that she isn't always sure he loves her enough or loves her at all.

* TinyGuyHugeGirl: Huge Girl to Otani's Tiny Guy. She is a [[HugeSchoolGirl girl who’s taller than average]] and he is [[TheNapoleon a guy with a height below most average guys]]. Do the math!

** Unlike her love interest, Risa tries to be dere dere with Otani. The problem is that when she tries, Otani ends saying things like “gross” or “weird” and that makes her mood changes of a "dere dere" one to "tsun tsun" in question of seconds.
** For example in "Declaration of War! The Dangerous Beauty Burns with Envy!" when Risa points out that Mimi must be depressed because Otani saw her true self, we get this:

* UnrequitedLoveSwitcheroo : With Otani. Played with. Risa falls in love with Otani, but Otani rejected her because he can’t see her like “more than a friend” (maybe because she’s taller than him too). Finally Risa gives up with Otani and she have a fangirl crush on [[HotTeacher Maity-sensei]]… Otani gets unwittingly jealous of Maity and finally realizes about his feelings for Risa in a [[GreenEyedEpiphany Green-Eyed Epiphany]] (invoked for Maity-sama.)
