Natsu no Arashi

Hajime Yasaka goes to stay with his grandfather over the summer in a small town. While he's there, he meets a girl, Sayoko Arashiyama. "Arashi" for short. When the two join hands, Arashi reveals that she "connects" with Hajime, and that she is also a ghost. When they connect, Arashi and Hajime can jump through time, which Arashi uses to show Hajime the past and, with his help, to correct it. In the present, she gets to know the modern era and work with the colorful cast of people at the cafe Hako-bune ("Ark", e.g. Noah's).

Based on the manga by Jin Kobayashi, creator of School Rumble, and adapted into an anime in the spring of 2009 by Studio Shaft, with a second season, ''Natsu no Arashi! Akinaichuu'', airing in the fall of that year.

Tropes in Natsu no Arashi! include:

 * Actor Allusion -- In episode 8 of the second season, Yayoi is wearing an Indiana Jones type of outfit. The same is often true for Ichijou from Pani Poni Dash, another Studio Shaft series. Both characters are voiced by Ai Nonaka.
 * Arbitrary Skepticism -- Hajime was incredibly suspicious of Arashi at first, being a science nerd. But an E.T. like moon leap was all it took for him to accept her. Sort of.
 * Author Appeal -- Belly buttons. Usually Arashi's.
 * Mostly in the anime version, it seems. The manga has more of this sort of navel observation and less of that sort.
 * Beautiful All Along -- Kanako can be quite attractive (at least in the eyes of the cast), especially when she wears glasses. Regrettably, she hates the idea.
 * Beach Episode -- Wasting no time to get on with it, the first episode of the second season.
 * Bifauxnen -- Jun, who makes a pretty convincing male, at least to Hajime. Though Jun's a pretty convincing girl, too.
 * Bishounen -- Yamashiro. Hajime cannot tolerate him for that reason.
 * Boisterous Bruiser -- Hajime and Arashi, who develops into this partly due to his influence.
 * Bottle Fairy -- A beer is Master's fuel for life.
 * Butt Monkey -- poor Hideo.
 * Cameo -- Pay close attention to the customers at the start of episode nine. You'll notice, in order Kiyosumi's mahjong club, the Hidamari Sketch girls, the K-On! girls and God and Father Kanae. Mesousa can be spotted in the same scene.
 * Charm Point -- Hajime states that Arashi's silliness is a part of her charm.
 * Christmas Cake -- "Master's expiration date".
 * Clingy Jealous Girl -- Kanako towards Yayoi at times. When it's revealed that Yayoi can connect with the Master as well, she wonders if Yayoi was corrupted by connecting with her.
 * Cool Big Sis -- Master, to a degree, Shades even calls her "nee-san" from time to time. Makes one wonder, how old is she...
 * Cool Shades -- Hideo, the man with the sunglasses hunting for Arashi.
 * Couch Gag -- Another part of a story about a mangaka, his girlfriend, and some aliens is shown in every episode's opening; the colors used for the nude Master and Yayoi, Kanako, Kaja, and Arashi silhouettes is also different every opening.
 * Cute Ghost Girl -- Arashi, Kaja and, though they don't display many "ghostly" signs. A slightly less cute one, , displays some more.
 * Date Peepers -- Time traveling date peepers. It's entirely possible.
 * Deadpan Snarker -- Jun sometimes gets tired from his friends' quirks...
 * Ear Worm -- The first season opening. Kake-kake-kake-kake-kakete!
 * Everyone Calls Her Barkeep: Or Master, rather, the Japanese equivalent. (Her names' Sayaka.)
 * Fish Out of Temporal Water -- All the ghost girls, but Kanako and Kaja have the toughest time adjusting to the present.
 * Five Man Band -- The primary squad of the Hako-bune:
 * The Hero - Hajime.
 * The Lancer - Jun.
 * The Big Guy - Master.
 * The Smart Guy - Kaja, altough sometimes Hajime himself takes that role.
 * The Chick - Arashi.
 * Sixth Ranger - Shades.
 * Fan Service With a Smile -- The Hako-bune isn't normally a Maid Cafe, but it comes pretty close to being one.
 * Played straight during the most part of episode 5, after Master makes everyone, including herself and Hajime, wear color-coded maid dresses.
 * For Want of a Nail -- Sankichi, a young man that Arashi saves in the past, goes on to become the father of Hideo, the man with the shades tracking her down in the present. See Timey Wimey Ball below for more on how Hajime and the rest dissect this issue.
 * Freaky Friday Flip -- Jun and Hajime swap bodies, which Jun finds troublesome. Mostly because of the gender issue.
 * Gender Vocabulary Slip -- Rather rare in public with Jun, but she goes ahead and slips right back into "watashi" when people aren't around. Rather softens the blow of the "reveal".
 * Glamour Failure -- All video with Arashi recorded on screen has noise running through it. Hints, hints.
 * Here We Go Again -- The last episode is a mirror of the first episode in many ways, right down to the titles. Which are, curiously, out of order. "Playback Part 2" was the first episode and "Playback Part 1" is the last.
 * Hey Its That Voice -- Arashi is Ryoko Shiraishi known for the role as Hayate.
 * Hajime and Kaja sounds like Renton and Eureka.
 * The guy who keeps asking for salt sounds like Kyon.
 * Scratch that, almost EVERYBODY not related to the main plot sounds just like him.
 * Yayoi is Fuuko and Kanako is Minorin.
 * And Jun is Maka.
 * Honest Johns Dealership -- The Master of the Hako-bune is a scheming con artist.
 * Hot Springs Episode -- Episode two of the second season. Mahjong playing included.
 * Ho Yay (and Les Yay) -- Both kinds of Yays, along with romantic tension in general, is in the air when Arashi has to do a kiss scene for a visiting mangaka in need of inspiration.
 * Idiosyncratic Episode Naming -- All the episode titles are the names of old J-Pop songs, mostly from the late 70s/early 80s.
 * Ignore the Fanservice -- Master's increasingly desperate attempts to net herself a guy at the beach fail by Kanako and Yayoi being nearby and being themselves.
 * Ill Girl -- Yayoi is.
 * Instant Awesome Just Add Mecha -- The Hako-bune, for no explained reason (and more Medium Blending) can turn into a giant robot. There's a remote for it.
 * Specifically it turns into the Daimos.
 * Instant Cosplay Surprise -- Jun really needs to watch what clothes are laid out...
 * Jerk With a Heart of Gold -- Shades. The Master of the Hako-bune can also show some good heart, when the money isn't involved.
 * Knife Nut --.
 * Latex Perfection -- An old man can disguise himself as a young girl with ease.
 * Likes Older Women -- Hajime proudly declares his preference of older, more developed girls. His fellow middle-schooler Jun is not amused.
 * Manic Pixie Dream Girl -- Arashi.
 * Mayfly December Romance -- take a guess.
 * Medium Blending -- A gag that gets used a few times is a cutaway to a shot of the Hako-bune getting wrecked as a live-action model.
 * Meganekko -- Everyone in episode 5 of the second season, when Master announces "Meganekko Day" for all of her workers. Speciffically, to make Kanako wear glasses, which gets her transformed into a Mahou Shoujo, to her great horror.
 * Moe -- Yayoi, full stop. And Jun, both versions.
 * Morality Pet -- Yayoi to Kanako, kind of.
 * Mundane Utility -- Time travel powers are abused to speed up fermenting time and to make doing things around the Hako-bune easier. Jun wonders if that's such a good idea.
 * Narm -- Hajime's extreme freak-out when he witnesses a firebombing in WWII Japan is way too long and just not scary enough.
 * Never the Selves Shall Meet -- The rules of time travel work as such: If you meet yourself, you vanish. Time doesn't want there being two of the same person in the same area. Maintaining a safe distance is necessary. This also makes it easy to whether you're, say, hiding around the corner, however; the closer you get to yourself, the more you fade out.
 * Once an Episode -- There's almost always the man in the back of the Hako-bune, asking for salt. He even goes so far as to interrupt Hajime's timeline graph to ask. At this point, the cast is probably not aware he exists.
 * Throw the Dog A Bone -- After 26 episodes spread across two seasons, with his existence being largely ignored, Arashi finally hands him some salt in the last episode of Akinaichuu.
 * Oddly Named Sequel - The second season is called "Akinai-chuu" meaning "Open for Business". Ignoring the fact that the main characters already spent 12 episodes working for the Hako-bune in the first season.
 * Actually... "Akinai Chuu" isn't written the way you'd normally write it. In Natsu no Arashi!, the word "akinai" meaning "business" is written with kanji "spring", "summer" and "winter". Missing the "autumn", eh? Japanese for "autumn" is "aki". No autumn = aki nai. Remember? Should the autumn come, Arashi and the crew will disappear, so the title holds special significance in that sense.
 * Onee Sama -- Kaja gives sort of that atmosphere to Jun.
 * Only Known By Their Nickname -- Shades. Real name.
 * Opening Shout Out -- The final episode has the cast doing their poses from the opening, with neither them nor anybody else acknowledging they're actually doing so.
 * Overnight Age Up -- Jun, in episode 11 of Akinaichuu, ages up and becomes a lot more feminine. Only Arashi knows it's really her. Everyone else thinks that Jun's her own older sister, Ryoko.
 * Private Eye Monologue -- Hideo, on a mission in the mountains. A beetle is crawling over him the whole time.
 * Romantic Two Girl Friendship -- Yayoi and Kanako show as much affection towards each other as an average pair of lovers.
 * Running Gag -- The guy asking for salt.
 * Scenery Censor -- Leaves fall very conveniently to obscure Jun's gender.
 * Second Hand Storytelling -- Episode seven of Akinaichuu is a time-travel heavy episode that takes place completely in the present day, with the audience only hearing of what happened three days ago.
 * Selective Obliviousness -- Hajime is unable to realize that Jun is a girl... despite groping her breasts couple of times, seeing her half naked and swapping bodies with her at one point. In the Hot Springs Episode, he sees her completely naked and still doesn't catch on.
 * Sensitive Guy and Manly Man -- or so it seems.
 * Set Right What Once Went Wrong -- Arashi and Hajime's time jumps are usually for this purpose. This is in contrast to Kaja, who believes that time is something not meant to be messed with.
 * Ship Tease -- Arashi and Hajime, Hajime and Jun, Shades and Kanako, Kanako and Yayoi, then Yayoi and Yamashiro-san
 * Shout Out -- It's a Shaft series, this is expected. Customers that look like Tenma and Harima can be seen seated in the Hako-bune in one episode, Yayoi and Kanako have a regular segment that alludes to other anime series, and the opening is a barrage of references to old CD covers.
 * Look at this.
 * The show subverts its own running gag when, in episode eleven, Master is able to correctly guess the anime (Glass Mask) before Kaja even gets the first sentence out.
 * Reimu's head is seen in the first episode.
 * Two customers look similarly to Amuro and Char on ep 5, with Tomokazu Sugita does his best Tohru Furuya and Shuichi Ikeda impression.
 * Also in ep 5 was the Hiten Mitsurugi Ryu.
 * PEGASUS RYUUSEI KEN!!!!!
 * In episode 1 of the second season two main characters of Yaranaika are shown trying to pick up Yayoi and Kanako.
 * There's a number of Eureka 7 shoutouts because of Hey Its That Voice. In second season Hajime is playing a fighting game as Renton.
 * At the end of episode 2, Conan, from the future, comes in as a customer.
 * In the middle of episode 3, during the Arcade Center sequence, two kids can be seen among the crowd doing the classic Fusion Dance Pose from Dragonball Z.
 * Who could imagine that an EarthBound reference could be so disturbing?
 * Signature Style -- You'll notice many of director Shin Ohnuma's idiosyncrasies (mainly those angular frames), a good deal of which were carried over from his Ef A Tale Of The Two adaptations.
 * Spoiler Opening -- The opening spoils Kanako's Heel Face Turn and Yayoi gaining the ability to walk (not that the first episode didn't).
 * Stable Time Loop -- There are quite a few, with the first episode having an increasingly complicated time loop. Everything from the events of the first/last episodes of the first season all the way up to how Arashi and Hajime met.
 * The Straight Man -- Jun and, to a lesser extent, Kaja, yes, a crossdressing girl and a ghost.
 * Surreal Theme Tune -- Second season opening theme makes less than no sense and has no relevance to the series itself.
 * Sweet Tooth -- Kaja, who's easily coerced into doing things for cake and takes her pudding very seriously.
 * Test of Courage -- One of these takes place at the hot springs. Yayoi is terrified of ghosts despite being one herself.
 * Thirteen Episode Anime -- Twice.
 * Title Drop -- In the penultimate episode of Akinaichuu, in the middle of an impassioned speech about helping those who come into the Hako-bune, Arashi works the series' name in.
 * In several episodes in the first season, the series' name is written across many places here and there. A particularly prominent time is during  during episode 10.
 * Timey Wimey Ball -- A good part of episode nine is dedicated to Hajime and crew trying to untangle the timey-wimey ball that makes up their universe. Mostly in the matter of "What happens to the timeline that was when we change it?"
 * This isn't made any easier by the fact that Master has zero understanding of how time travel works. She thinks that leaping back ten years would make her into a sexy teenager again, when it would really just set the current her in a different time.
 * Transformation Sequence -- Arashi and Kaja change into their schoolgirl uniforms just before they time leap. The sequences are usually short, but always flashy.
 * Tsundere -- Jun is a B type. Anyone at her place would run out of patience around Hajime.
 * Visual Innuendo -- while Kanako appears anything but heterosexual, interestingly, she has a thing for cucumbers of all of things.
 * What an Idiot -- While spending time in Jun's body, Hajime realizes his balls are gone and his chest is bigger. Surely the balls fell off somewhere.
 * White Haired Pretty Girl -- Kaja.
 * Wonder Twin Powers -- Two are needed to time travel.
 * Yamato Nadeshiko -- Lampshaded by the Master in reference to all four girls. In fact only Kaja, the German, fits perfectly, Arashi not so much, Yayoi is more of a Kawaiiko, and Kanako can be called the opposite of it.
