Amano Sakogami is a girl who has an unnatural amount of bad luck. One day, she stumbles into the clubroom of the Better Fortune Research Organization, which consists of a boy and seven other girls who secretly use the power of the luck deities to fight against the Magatsugami, monsters who can affect a person's luck & well-being. Amano soon becomes the club's manager, and joins the club in their fight against the Magatsugami and their controller, Kukitomoe.
Happy Seven is your average magical-girl anime, with an above-average amount of magical girls.
Note: I don't know anything about the seven lucky gods, so I can't say anything about how well the legend is implemented.
Okay, quick run-through the basic points:
Mysterious power under the school,
a club made of seven magical girls, one magical guy and a couple of support girls, that goes around fighting monsters that possess people, and also help people be a bit happier in general,
a couple of evil characters scheming in the background,
and one girl the club helps that might just be special.
The show focuses on the special girl, Amano, as she stumbles
along after the club (More specifically, the guy), or into trouble on her own. And she just happens to look 90% like Usagi aka: Sailor Moon. She's also dim, a bit of a clutz, and quickly falls for the magical guy, also like Usagi. The only real difference from Usagi is that she can't transform. I guess that's something.
Meanwhile, the club goes around doing it's thing, but somehow, they feel like secondary characters. This is more noticable when everyone is together, and a conversation involves everyone saying a single line. They just try so hard to give all the magic girls equal screen time, that none of them really get enough to feel like major characters. The magic guy doesn't fare much better, wandering in and out as needed to smile or save the day. One thing I did like about the club, is that they actually go out and help people with things that don't require magic. They also have talents beside magic, though it does make me wonder if they all grew up in the circus.
The story is kind of nice, but it's pretty much just background up until the last couple of episodes. Unfortunately, how the club got it's powers is never explained. I guess you'd have to read the manga.
The combat is fine, and the special attacks look nice. Also, the transformation sequences don't take too long.
That leaves the humour, which is really the driving force behind whether you'll want to watch this series. The humour is mostly character-based, each of the girls having some odd trait or two to derive humour from, though they do repeat a bit. There's also the fact that almost a dozen girls love the same guy. It's difficult without giving samples, but I'd say the humour is decent, with a few particularly nice bits.
Overall, the series is decent, and there are some nice bits, but most of the time, I couldn't shake this feeling of flatness/blandness, which may come from having too many characters trying to share the spotlight. If you like the transforming-magical-girl genre, or characters cloned from Sailor Moon, then it wouldn't hurt to check this series out, but I can't say you'll be missing out if you skip it.
the anime Happy seven i really like it because the powers of the characters came from the the 7 Lucky gods and i really like the figthing style and the way they fight they are also good helping other people to have good luck one of my fav character is Kuriya Kuroda (Houko Kuwashima): She represents Daikokuten. She carries a hammer. i really like the combination of their weapon called the sky cannon or dual cannon.this power can only be used when she combine her hammer with one of the happy seven who uses a guitar as her weapon.this anime is really cool
