Clockwise from top: Sumomo, Anri, Haruhi, Koyuki. Not shown: Jun◊
Originally a Visual Novel, Happiness was adapted into an anime for the fall 2006 season.When she was a young girl, Kamisaka Haruhi was saved from some bullies by a young boy who used magic to chase them away. Even though she never learned the boy's name, she was inspired to learn magic herself, so that she could help others just like she had been helped.Flash forward to the present day, where Haruhi is now the top student in her grade at Mizuhosaka Academy, a school which teaches both magical and normal students, although the two groups use separate facilities and rarely interact. On Valentine's Day, Haruhi buys chocolate in hopes that she may encounter the boy who helped her out many years ago, but fails to find him, and thus decides to just give the chocolate to Kohinata Yuuma, a random student from the normal section of the academy. That night, there is a gas explosion in the facilities used by the mages, and so the mage students are transferred into the normal section of the school while repairs are being completed. Haruhi and her friend, Anri, find themselves in a class with Yuuma.Rounding out the cast are Jun, a boy who wears the girl's uniform to school, Hachisuke, who is Yuuma and Jun's friend, Sumomo, Yuuma's sister who Haruhi used to play with when the two of them were younger, Koyuki, the fortune-telling daughter of the school administrator, and mysterious transfer students Ibuki, Saya, and Shinya.Not to be confused with the Todd Solondz film of the same name. Or, you know, the emotion.
Action Bomb: When everybody attempts to create their own Tama-chan, Anri's attempts to blow everybody up. According to Koyuki, this is an ability that all Tamas have (thus she was able to realize what was going on in time to send it far away), but had never had one that actually tried to do it before. Later, the result of the failed attempt to recreate the Ancestor Sphere-tom does the same thing.
A-Cup Angst: During the beach episode, Sumomo mentions that she wishes she were as developed as Haruhi and Anri. When her mother assures her that she's still growing, Sumomo claims that hearing that from her mother (who is still wearing her School Swimsuit) managed to make her less confident.
Attractive Bent-Gender: Even Hachisuke and Yuuma sometimes forget that that Jun is a boy, resulting in the two of them imagining him in various fetish outfits until Jun tells them to cut it out. Lampshaded in the OVA, where the boys are drooling over the (now actually female) Jun, and Yuuma points out that he doesn't actually look any different.
Fortune Teller: Koyuki does this to get more of the school's female population to go to the Oasis cafe, by telling them that they have bad luck, but eating various menu items from Oasis will negate it.
Gainaxing: Most of the female characters during the beach episode.
Gender Bender: The plot of the OVA is that several people's spells accidentally combine and turn Jun into a real girl. The end reveals that Yuuma also got hit by the spell.
Genki Girl: Anri. Sumomo is also rather energetic.
Give Him a Normal Life: This was Miinagi's reasoning when she erased Yuuma's memories and sent him to live with Otoha, because she knew that she had to remain at school at all times to protect the Shikimori treasure and couldn't make enough time to properly raise him.
Gone Horribly Wrong: The attempt to create the ancestor Sphere Tom results in a "bad" tom, which almost destroys the city
Green Thumb: Attempted by Anri to help catch the "intruder". One of the few times her magic works as directed, although telling the plants to "catch the intruder" when she herself was trespassing at the time was not the best command.
Hadaka Apron: Suggested by Hachisuke when Anri gets a job as a waitress working at the school cafeteria. The others are not very appreciative of his idea.
It's All My Fault: Happens twice to Yuuma: once in his backstory, where he could have (but didn't) hurt the boys he used magic on to save Haruhi, and once towards the end of the series, where his magic almost kills Sumomo.
Magic Wand: Standard equipment for mages, implied that this is required for them to cast magic (although they are never seen without their wands, so this can't be confirmed). Despite being called "wands", they're really more like staves
Magic Misfire: Done for laughs several times with Anri. Used more seriously when Yuuma's inability to control his magic almost results in Sumomo's death.
Meido: Anri's (self-made) uniform while she works at Oasis.
Me's a Crowd: Anri's solution to there being do many customers at the cafe for her to handle. This being Anri, it doesn't really go as planned.
Mundane Utility: Anri attempts this, but usually screws up, such as trying to set up all of the chairs for the assembly, but accidentally putting them on the ceiling (at which point gravity kicks in), or turning the rain into sake rather than creating a barrier to stop it from falling on them.
Musical Assassin: Shikimori Natsune has a flute which channels her magic while she plays it. This flute is later given to Yuuma for the final battle, before he returns it to Ibuki. In addition, Saya and Haruhi's wands were musical instruments (a violin and trumpet, respectively), but seem to have no actual connection to music, aside from Saya's attacks having music-themed names.
New Transfer Student: Haruhi and Anri, due to the collapse of the facilities of the magic section of the school. Saya and Shinya also transfer in later.
One Degree of Separation: Only to a certain extent, but Anri accidentally hits Yuuma with a spell, who just happens to be the boy Haruhi met recently, the brother of Haruhi's childhood friend, and the son of one of the cafeteria workers. The truth is he's actually adopted, his real mother is a teacher at the school. Yuuma is also the boy who saved Haruhi when she was young and inspired her to be a mage. In addition, Yuuma's mother, Koyuki's mother, Ibuki's sister, and Saya and Shinya's father were all acquainted with each other.
Self-Fulfilling Prophecy: A fortune teller tells Haruhi as a child that she would someday give chocolates on Valentine's Day to the boy who inspired her to become a mage. She ends up buying chocolates every year, so she'll be prepared for that day. On Valentine's Day, she watches Yuuma try to protect a young girl against bullies, but is unsure he is the same boy because he didn't use magic. Still, as she as amassed so many chocolates over the years, which have gone to waste, she gives this years chocolates to Yuuma, unknowningly fulfilling the prophecy.
To Be a Master: Anri's goal is to become the best mage in Japan (and eventually, the entire world).
Transfer Student Uniforms: Shinya wears his old uniform, despite the fact that Saya apparently had her new uniform at least two days before transferring.
Those Two Guys: Role fulfilled by Jun and Hachisuke, although Jun is hardly what is usually encountered for this role.
Transsexual: Strongly suggested in Jun's case - overjoyed upon being accidentally turned into a girl, even after seeing the disastrous side effects, most of the episode is spent convincing her to turn back.
Unknown Rival: When they started high school, Anri attempted this to Haruhi (since Haruhi had the highest test scores out of the incoming class), but Haruhi simply acts friendly towards her, noting that everybody else so far had been rather polite and distant to her until that point.
Unsettling Gender-Reveal: Probably the biggest example this side of Bridget himself. Haruhi is rather shocked when her classmates inform her that Jun is really a boy.
What Measure Is a Non-Unique?: The 984th Tama becomes depressed because it thinks that all Tamas are the same, and that it can be easily replaced. This turns out to be not true; Every Tama has it's own unique personality, and Koyuki remembers the things that make each one unique, and can identify them on sight.
Wooden Katanas Are Even Better: Shinya uses a wooden katana, which draws raised eyebrows from the main character until Haruhi points out that it's also his wand, and thus the material that his sword is made out of is mostly irrelevent.
