When thirteen-year-old Hajime goes to stay with his grandfather he gets lost and wanders into the Ark Cafe. There he meets Arashi, a sixteen-year-old girl with a big secret, and is immediately drawn to her. When a large private detective clad in camouflaged trousers and dark sunglasses walks into the cafe looking for Arashi, Hajime manages to help make him back off - for now. In thanks, Arashi goes to shake his hand but as she does so the pair connects and Arashi takes Hajime back in time to show him how the town used to look... while she was still alive! Now, after being ‘won' in a bet by the con artist currently managing the cafe, Hajime is working alongside the ‘ghostly' Arashi and fellow middle-schooler Jun who also suffered the same losing fate. As his life takes this unexpected turn, Hajime's stormy summer filled with student movies, moped races, and plenty of time travelling is only just beginning.
Kanako Miyamae hates boys so much that she breaks out into hives after any physical contact with them. So when she is able to transfer to the Ame no Kisaki Girl's school, Kanako is overjoyed that she can now search for her fated yuri partner. When she arrives, Kanako meets Shidou Mariya, a beautiful young girl who is exactly her type... except that Mariya is really a sarcastic and sadistic young boy who is masquerading as a girl! With no intention of being expelled from school, Mariya threatens Kanako into keeping his secret, and decides to guard her twenty-four hours a day to ensure that she does. Now Kanako must share a room with Mariya who is gleefully making her life a misery while using his ‘feminine' charms to stop her protesting. Throw into the mix Ryuuken, the most popular girl in school who has vowed to protect her; and Kiri - who claims they are dating to prevent her from being bullied - and it seems as if Kanako's dream of all-girl school life will be nothing like she imagined!
I cannot see the similarity in any other way between Natsu no Arashi! And Maria Holic other than the type of random comedy these two series deliver. Although that humor plays a big role in each of the series, making them in my mind extremely similar.
Teiichi Niiya is a first year middle-school student at Seikyou Private Academy, an institution known for mysterious occurrences. The boy quickly finds these rumors to be true when he meets Yuuko Kanoe, a beautiful, mischievous girl who quickly takes a liking to him... and happens to be a ghost who seemingly no one else can see! Unable to remember anything about her past, Yuuko enlists Teiichi’s help to discover the truth, and together they join the school's Paranormal Investigation Club. With fellow memebers Momoe and Kirie, the pair will investigate the many strange happenings around campus, including the shadowy circumstances surrounding Yuuko’s death.
A boy meets a ghost girl and falls in love with her. The two of them (along with some other friends) spend their time solving mysteries, out of which the most important one is: why did the girl become a ghost in the first place?
What does all that have to do with Natsu no Arashi! and Tasogare Otome x Amnesia? Thats the basic plot of those two series. In other words, if you thought one of those series was interesting, you'll probably find the other one interesting too.
