If you liked the The Melancholy of Haruhi Suzumiya anime, the Anime-Planet community thinks you'd like:
Since long ago, the wolf goddess Holo has honored a contract to bless the rural village of Pasloe with fertile harvests; and in return she has been celebrated and worshipped by the villagers. But as mankind advances, the people have begun to take command of nature for themselves and have made their own god to worship. Holo finds that she is paid little more than lip service, if not outright mocked; and considering the contract annulled, she takes human form and enlists the aid of a passing merchant, Kraft Lawrence, to return to her home in the snowy forests to the north. As they journey together, Kraft finds that he has plenty to learn from this capricious god, and she from him as well.
These two series have a similar pair of protagonists: one is a weird, energetic girl with god-like powers and the other is a straight, no-nonsense guy who deems himself mature and experienced. The gradually developing bond between them is a major subplot of both series. The other is the exploration of their respective worlds, which tend to follow some really obscure laws.
Forty years ago the citizens of Paradigm lost all of their memories, and live their lives without any knowledge of their past, or any hope for the future. Roger Smith is a man who performs the much needed task of negotiator in Paradigm. He provides his services to the wealthy with the help of a peculiar android named Dorothy and his mechanically inclined butler Norman. When greater evil arises, he calls on his magnificent relic of Paradigm's past, the Megadeus Big O. With Big O at his side, Roger Smith may be Paradigm's only hope of surviving in this new world without memories.
Postmodern fiction is known for being a self-referential, non-linear hodgepodge. The Melancholy Haruhi Suzumiya and The Big O are good examples of this movement.
Haruhi Suzumiya and The Big O manage to combine disparate genres without missing a beat. The former is an absurdist high school comedy; the latter is a mecha neo-noir. Like Tarantino's Pulp Fiction, these shows make extensive use of homage and pastiche. The Big O is a tribute to the Japanese and Western cinema and television of the 1960s and 1970s, while Haruhi Suzumiya is layered with innumerable pop culture references, from Stoppard's Rosencrantz & Guildenstern Are Dead to Capcom's Ace Attorney series.
Keeping with the postmodern sensibilities, both have moments that play with the line between reality and fiction, like Roger's line ("I'd have to say you have the wrong guy. I'm not exactly a bounty hunter.") in Act:17, a reminder of the voice actor's turn as Spike Spiegel in Cowboy Bebop, and a poster of Aya Hirano ("Haruhi"), Minori Chihara ("Yuki") and Yuko Goto ("Mikuru") in "Mysterique Sign".
If you like your anime unconventional, look no further than these two.
At the end of World War II, Japan was split and a great tower was erected that reached the skies. For three friends, Hiroki, Takuya, and Sayuri, memories of their summer spent together would stay with them forever. During that precious time, the three promised to one day travel to the tower in the skies on the wings of a white plane -- to finally see its brilliance and the surrounding land of Ezo -- but when Sayuri suddenly disappeared from their lives, the promise that once was made was broken. Though time continues to pass, will the three ever meet again some day?
The Place Promised In Our Early Days has just as many psychological ideas and questions that Haruhi has. Either one is likely to give you an aneurysm from thinking too much. They are just my style. :]
Touma Kamijo's right hand has the ability to nullify any form of supernatural power, whether it be magical, psychic, or divine; he lives in a city populated by students with these powers. Yet unfortunately for Touma, his arm also seems to nullify good luck. Despite his bad luck, the boy tries to stay out of trouble and just live out his life, trying to be the "good guy" whenever he can; but trouble enters his life one day when he finds a young girl hanging on his balcony. She turns out to be a nun of the Church of England, bearing the Index-Librorum-Prohibitorum - a collection of 103,000 forbidden texts, and as a result has a number of people after her. How far will Touma go to protect his new companion from her pursuers?
Espers, magic, high school, and moe. Not to meantion GREAT animation. Althogh Melancholy is where the main character is trying to look for these Espers, the Espers are everyday people in Index. Not to meantion The Espers and Magicians of Index reside with each other, yet do not know. While in Melancholy, Aliens, Time Travelers, and Espers also reside in the world, but are not known to the humans. there are exceptions to this in both animes: The main guy character knows they all exist, and so does his otherwordly friends.
It’s a new year, and a new group of students is moving on to high school. Takaki Kono is a shy young man who has a variety of friends including the perverted Yuuji and overly-emotional childhood friend Konomi. Along with the usual responsibilities of attending classes and studying hard, Takaki finds himself involved in the lives of many young ladies as well. Whether it’s with class representative Komaki, wealthy and combative Yuma, Yuuji’s confident older sister Tamaki or yet another girl, Takaki finds himself always caught up with a new girl and a new challenging or playful experience!
Weird quirky characters surround both of these anime and a similar theme of alien catching or being obsessed with them. To Heart 2 is more just a guy spending time with all these different girls who like him and very light hearted. Where The Melancholy of Haruhi Suzumiya takes things in a spastic confusing way and isn't to tender loving. I suggest you check either of these out if you liked the other.
