In present day Japan, the life of a school girl is never dull. The easily-bored Konata never finds time to study because of her otaku habits, which frustrates hard-working Kagami to no end. On the other hand, laid-back Tsukasa always manages to go with the flow, while Miyuki is concerned with keeping her status as resident know-it-all. Join these four girls as they muse and meander their way through everyday events such as eating chocolate cones, doing homework, gaming, and trips to the beach galore.
Negi Springfield is a typical ten year-old Welsh boy -- except that he's a mage, and an English teacher at an all girls school in Japan! In order to become a full mage he has to prove himself as a teacher and find suitable partners to aid him; but above all, he has to make sure that no one discovers his secret. Much to his dismay his secret is discovered on the first day by one of his students, Asuna. To prevent Negi from being punished, Asuna agrees to become his partner -- however she isn't the only one to find out. As time goes by more of his students find out his secret. How long can he keep his powers hidden when little by little all of his students are becoming his partners?
Both Negima!? and Lucky Star are fast-paced and stuffed full of in-jokes and quickfire verbal and visual references, demanding a lot of background knowledge from the viewer. While it is possible to enjoy either without the anime experience and cultural ballast, these are definitely a bonus to the viewers.
Though the setting is very different, these two anime share several traits. They are both chibi style anime that revolve around a group of weird friends (mostly girls) and the shows portray a slice of their everyday lives with comedy. The main character in both shows is also a laid-back gamer.
Yuuto Ayase is not interested in girls - if his two housemates are anything to go by, girls are loud, brazen slobs that are best left alone. However, when Yuuto accidentally discovers an important secret of his school’s most popular female, Haruka Nogizaka, the two become bound in a budding friendship. All too soon, Yuuto discovers that, despite her flawless appearance, Haruka is clumsy, naive, and a closet otaku... and he just might be falling for her.
Both Lucky Star and Nogizaka Haruka no Himitsu are centered around the idea of otaku culture (video games, anime, etc.). While Lucky Star is a slice-of-life centering around four main girls, Nogizaka Haruka no Himitsu is a romantic comedy involving a girl that no one suspects to be an otaku and the guy who found out about her.
Kyousuke Kosaka is a normal teenager with average grades and an average home life, but when he finds out that his overachieving younger sister Kirino has been hiding her vast anime and eroge collection from their unassuming parents, his world turns inside out! Now, having promised to help his formerly distant sibling navigate her two distinct lives, Kyousuke finds himself drawn into Kirino's world of magical girl anime and "little sister" fetish games while covering for his sibling to her parents and friends, not to mention trying to provide what guidance he can.
Both of these series star a very otaku girl in a comedy and slice of life-esque series. If you enjoyed all the anime, gaming, and other references in one series, you'll probably like the other. The biggest difference in the series is that Lucky star is almost completely episodic and random while Ore no Imouto has a plot it follows and a lot more character development.
Tragedy struck Kotaro Higuchi as a child in the form of his mother's death in a car accident. But fate has a funny way of doing things, and years after the fact an angel-in-training named Misha decides to pay him a visit. Joined by his fellow elementary school students, and later by the nicest demon you'll ever meet, Kotaro and Misha will embark on a journey of laughs and love.
If you liked Lucky Star, then I would highly recommend Pita Ten. Both have a relaxed plot, and both have adorable art with adorable characters. Plus a little bit of comedy is put into Pita Ten, just like in Lucky Star.
