Ruri loves a construction sign to not be heartbroken
Ruri's misfortune of tragic love means she's destined to fall in love and be heartbroken. This may have already happened in the past. An episode in the anime shows a flashback that has a young boy, seemingly causing Ruri unhappiness. Additional flashbacks of her past, reveal Ruri takes criticism and rejection very hard. Falling in love with an inanimate object, means it can't emotionally hurt you directly. Ruri's actions are like someone withdrawing into psychological denial to hide from pain and suffering. Her childhood memories of the construction sign, might be delusional substitutions of a real boy she had feelings for, but got rejected by.- Because the girls seem to inherit misfortunes from their mothers, the marital status of Ruri's parents might be divorced.
Kodaira-sensei used to be a student in Class Seven
Her "misfortune" appears to be gluttony and having a bipolar personality.Anne (Hanako)'s four-leaf-clover hairpin is actually a good luck charm
It has been noted so far that Anne has terrible luck, but that it somehow tends to warp around into having good luck. Her bad luck almost never has any significant consequences for her, nor causes any lasting harm. However, the two times so far (written as of episode 7) when she has lost her hairpin, this rule no longer seemed to apply. Her bad luck became notably worse, without any good luck to balance it out. The first time she fell into a stream, was swept away, hit by falling rocks, attacked by fish, mocked by monkeys, and finally dragged herself out and collapsed unconscious out of sight some distance away from any help, before finally being attacked by a bear. The second time... well, it's mostly unintelligible, but it seems to involve animal attacks, a thunderstorm, a stolen umbrella, falling in a stream, getting herself and her belongings (including her towel) completely soaked, having the ceiling in the classroom collapse in on her and let a miniature waterfall smash down on her in her seat just after she'd been dried off, and getting a fever that lasted several days. Not even to mention the extremely unsettling aura of doom that was surrounding her house when Ruri and Botan went to visit.Although the first case is harder to judge due to the way things turned out, the second one we can certainly say that most of those problems went away as soon as Anne's hairpin was fixed and she put it back on. So, conclusion: Anne's hairpin is actually a good luck charm either created, or at least used, to counter the worst of her own absolutely terrible luck. In fact, it may well be the only reason her misfortune hasn't gotten her killed yet.
- This guess is weakened, but not completely jossed, in the manga; as the anime adapted the manga out-of-order. In the manga, Anne's sickness is a direct result of falling into the stream during the hike, and lasts only one day. Although, Anne did say that hairpin is a family good-luck charm (of which Ruri doubts its effectiveness).
Class 7's purpose is not about "luck"; it's a group therapy
Some viewers have noticed Kodaira-sensei's use of the word "unfortunate" is patronizing or at least paternalistic. Well it is, but it seems she has no better word to use. If you look at the cast, they don't really have "misfortune" in the usual sense of the word (Anne excepted), but they do have relative mild issues that have the potential to cause serious issues—the more obvious are Hibiki's Small Name, Big Ego and Hibiki's Plucky Girl tendencies she mentioned in episode 9, but Ren's apathy and Botan's lack of self-esteem is also above what can be seen as normal, despite the cast looks fine right now. That's why Class 7 has long been called the "Happiness Class," its main purpose is to prevent at-risk teens (literal meaning of the word) to become actually "at-risk" (in teacher-ese, i.e. really messed up) by trying to handle their problems.All students in Class 7 have high latent skills or talents
Seeing as Tennomifune Academy is a school, and a prodigious one at that, there is no reason for them to accept such average and arguably burdensome students such as the ones in class 7 into their school. Saginomiya-sensei from episode 9 and volumes 2-3 initially openly expresses her disapproval of class 7, thinking that the students only play around all day. In the manga (volume 3) however, she elaborates on the flashback that was shown in the anime, where a student breaks down over how some student from class 7 "pulled one over on all of us" in grades. The student even says that "they were totally average until the fall of our second year. They weren't even competition!" From this it can be theorized that the students of class 7 all are indeed very gifted but are weighed down by their bad luck/karma.- Hanako is terribly unlucky but is skilled in arts and crafts.
- Botan is frail but her parents are doctors, and she too knows a lot about medicine and chemicals.
- Hibari is emotionally reserved but has extensive knowledge on plants.
- Hibiki has no sense of direction but seems relatively athletic (formerly the ace of the track and field team) and is also artistically talented.
- Ren is a sleepyhead with girl issues but proves to be very reliable and likely athletic.
The particular method the school seems to have chosen to fix their student's problems is "the power of friendship". Although not as apparent in the manga, the anime pushes this point much more, having the main cast help each other and resulting in some heartwarming moments. The point might not even be to cure their issues wholly, but to have them learn to cope with their situations and have their friends aid them too, such as how Hibiki and Ren deal with the other's problem for them.
- Confirmed as of Volume 6.
