''I"s'' is a RomCom manga series by ''Manga/VideoGirlAi'' creator Creator/MasakazuKatsura.

Ichitaka Seto is a normal Japanese high school student. His one hang-up is that due to a particularly nasty rejection by a girl when he was younger, he can't properly show his affection to anyone he's interested in. Naturally, he's crushing hard on Iori Yoshizuki, a classmate in the drama club that has found a sudden increase in popularity after posing in a swimsuit for a magazine spread.

Despite the seemingly impossible divide, Ichitaka lucks out when he and Iori are appointed to do a skit to welcome incoming students to their school. But his own nature, in addition to his friend Yasumasa Teratani's sometimes ill-advised help, inevitably trip him up. Matters aren't helped any when an old friend of his, Itsuki Akiba, shows up and starts crashing at his place.

The series' name has multiple meanings – it refers to the main characters' initials, but also to ''ai'', Japanese for both "love" and "sorrow". Also, the title is supposed to have two apostrophes (to represent the multiple "I" people), but it's usually written with a quote mark (in part for simplicity and in part because writing it correctly messes with the formatting of wikis like this one).

Running for fifteen volumes, it was adapted into two separate {{O|riginalVideoAnimation}}VA series, a PlayStation 2 game (which adapted the entirety of the manga) and made a surprise appearance in ''[[VideoGame/JumpSuperStars Jump Ultimate Stars]]''.

In September 2017 it was announced that ''I"s'' was being adapted into a live-action TV drama, with actor Amane Okayama in the leading role as Ichitaka Seto. The series will film in September - December of 2017, and it will air on the SKY PerfectTV! satellite network in 2018.

!This series has examples of:

* AbhorrentAdmirer: Iori has a legion of these. It goes from the ultra-jealous {{jerkass}} in her class (later ditched from the true companions because of it), to a multiple-attempted-rapist.
* AbortedDeclarationOfLove: Too many instances to count. They range from an unexpected event interrupting, or someone losing their nerve at the last minute.
* AbsenceMakesTheHeartGoYonder: Ichitaka does this post-high school after he believes Iori's given up on him for good and invoked this herself. [[spoiler:She didn't.]]
* AccidentalPervert: Ichitaka, though it's not ''always'' an accident (although getting caught isn't his plan).
* AirplaneOfLove: In the two-part OVA.
* AllJustADream: Played with, before being subverted. [[spoiler:Right at the climax, we suddenly go back to the beginning, and it looks pretty convincingly like the entirety of the story was this, aside from the very first chapter… until things go wonky and Ichitaka realizes his ChristmasMiracle (of getting a chance to redo his romance with Iori from the start) was the ''real'' dream.]]
* AllLoveIsUnrequited: Played maddeningly straight… [[spoiler:until near the end. Prior to the finale,]] nobody seems to be able to keep a healthy and stable relationship.
* AllMenArePerverts: Aside from [[StraightGay Jun]], all teenage males in this series who are around for at least three panels are probably going to make some sort of lewd comment about females. This includes our protagonist.
** And the worst ones are would-be rapists.
* AngstComa: [[spoiler:Happens to Ichitaka during the climax. He manages to defeat The Marionette King before Iori can be hurt, but suffers a blow to the head in the process and ends up in one. It takes Iori's voice to snap him out of it.]]
* ArtEvolution: Overlaps with the CharacterDevelopment. The appearance of the protagonists in [[http://manga.animea.net/i-s-chapter-140-page-19.html later chapters]] is quite different from [[http://manga.animea.net/i-s-chapter-1-page-43.html the beginning]].
** Basically, ''I"s'' is where Katsura's art style changed from ''Manga/VideoGirlAi'' to ''Manga/{{Zetman}}''.
* AttentionDeficitOohShiny: Ichitaka's imagination runs wild at many, many points in the story. It gets him in trouble more than once.
* AttractivenessIsolation: The ''only possible'' explanation for why Iori is not once seen to date anyone during high school.
** Well, that plus [[spoiler:she's had a crush on Ichitaka for as long as he's had one on her.]]
* AuthorAppeal: Katsura is a big ''Franchise/{{Batman}}'' fan, and the series is littered with references to it.
* AuthorAvatar: There are hints that the author is speaking through Itsuki in the final scene.
* BadassLongcoat: Would you believe that it's the openly gay ShrinkingViolet Jun?
* BeachEpisode: Twice in the manga. Once fairly early on, and then the entire 8th volume (the exact midpoint of the story) is one.
* BelligerentSexualTension: The Ichitaka/Itsuki pairing ''might'' have worked if they weren't so busy being complete jerks to each other.
* BetaCouple: Teratani and Yuka. Their relationship serves as a perfect mirror to Ichitaka and Iori – When I/I are feeling awkward at the beginning, Teratani and Yuka are already getting alone fine. During Christmas, when [[spoiler:Ichitaka and Iori ''finally'' become a couple, Teratani rejects Yuka.]] Only at the ending are both couples doing well.
* BettyAndVeronica: Iori is the Betty. Every other girl Ichitaka shows interest in (or shows interest in him) is a Veronica, most notably Izumi.
* BewareTheNiceOnes: Openly gay-or-bi, ShrinkingViolet Jun Koshinae. Do '''''not''''' [[BerserkButton seriously endanger his friends]]. If you do, cue CurbStompBattle.
* BigDamnHeroes: [[spoiler:Ichitaka valiantly tries to save Iori from being assaulted on three occasions. For the second rescue, Ichitaka owns the moment in the manga. In the anime, it is Teratani who saves the day.]]
** Given the intensity of the 2nd rescue scene, don't feel silly if you cheer a little [[spoiler:when Teratani shows up with the cavalry.]]
* BoyMeetsGirl: It's a RomCom, so this is pretty par for the course. [[spoiler:We learn later Iori considered it "Girl Meets Boy".]]
* BreakTheCutie: While none of these kids get broken to nearly the extent of [[Manga/VideoGirlAi some of Katsura's other characters]], they certainly suffer some damage. Here is a tally…
** Iori's rehearsal regime is designed to break her on the theory that it will make her a better actor.
** Itsuki when she realizes she'll never have Ichitaka's heart.
** Aiko when her boyfriend dumps her.
** Iori when [[spoiler:she is almost raped for the second time.]] It's amazing the girl doesn't seem to need therapy by the end. But then she IS an actress…
* CannotSpitItOut: Ichitaka has this problem due to being rejected ''once'' in sixth grade. In his defense, the girl ''was'' pretty cruel about it. [[spoiler:Iori has the same problem, but in her case, it's due to thinking that Ichitaka was in love with Itsuki.]]
** Jun Koshinae has this to Mr. Higemi, which is understandable considering the teacher-student dynamic ''and'' the same-sex issue. [[spoiler:By the end, we never learn if Jun spit it out or not.]]
** There are a ''lot'' of indications that Jun has this for Ichitaka in a bad way. Since he knows that Ichitaka is very much ''not'' gay, would never return his affection, and any confession would likely freak Ichitaka out to the point that Jun would lose the friendship he does have, he [[IWantMyBelovedToBeHappy instead does his best]] to be TheMatchmaker between Ichitaka and Iori.
* CasanovaWannabe: Teratani. It is ''heavily'' implied all his male relatives are like this too.
* CensorSteam: There was some during the bath scenes in the original Japanese release. There was even more in the English edition. The editing was evidently done with Katsura's permission, and may have been at his request to ensure an American release.
* CharacterDevelopment: Loads and loads and ''loads''. By the end of the series, everyone has ''noticeably'' grown up from their initial introductions not only physically, but also emotionally. Dramatic enough that when you get to the flashback event at the end of the series you will be absolutely shocked when you realize how far everyone has come and how naturally it progressed that you never noticed.
* CherryBlossoms: Very beautifully used.
* ChildhoodMarriagePromise: Ichitaka and Itsuki, at least according to Itsuki. [[spoiler:Subverted because nothing comes of it. However, Iori knew about it and assumed Ichitaka took it seriously.]]
* ChristmasMiracle: Deliberately invoked, and referred to by name several times thereafter, but it can't really be explained as well as an excerpt can demonstrate, so…
-->[[spoiler:'''Ichitaka''': "…In the end, I didn't get to confess my love either."\\
'''Iori''': "Confess your love to who?"\\
'''Ichitaka''': "Eh?"\\
'''Iori''': "Who were you planning… to confess to?"\\
'''Ichitaka''': "To you." [internally] ''I said it.''\\
''[another beat; Iori stares at him; the train stops, and she silently walks off]''\\
'''Ichitaka''': [internally] ''She just left without saying a word! Say something! Please! Give me some kind of reaction!'' [{{beat}}] ''So… that's it, then. So that's reality. That's how it ends; it was over so quick. And from now on, I probably can't even talk to her. What about college? Should I apply to the same one as her, or someplace else? I guess it doesn't matter.'' [*tearing up*] ''Nothing matters… not anymore.''\\
''[Ichitaka looks up; Iori has walked back onto the train; they look at each other for quite a long time]''\\
'''Iori''': "I thought… it was one-sided."]]
* CleaningUpRomanticLooseEnds: Zig-zagged. [[spoiler:During the epilogue, Itsuki sends a video from America revealing that she's fallen in love with someone. However, Izumi and Aiko are still single at the end.]]
* ClingyJealousGirl: Izumi for Ichitaka.
** [[spoiler:Iori acts this way from time to time after she and Ichitaka get together. Especially when she sees Aiko.]]
* ComingOfAgeStory: Duh.
* ConverseWithTheUnconscious: [[spoiler:Iori to Ichitaka in the finale.]]
* ConvenientComa: [[spoiler:Ichitaka. Given the circumstances of it and how long he was out, he would realistically have serious brain damage.]]
* CompressedAdaptation: ''I"s Pure'' takes dozens of chapters of manga and compresses them into 6 OVA episodes. In the process, a few characters get cut out completely (most notably Jun and Aiko), among other things. The video game is a full adaptation, however.
* DaydreamSurprise: A running gag for Ichitaka.
* DeclarationOfProtection: [[spoiler:'''"I will protect Iori for my entire life!"''']]
* DistressedDamsel: [[spoiler:Iori is almost raped. Twice.]]
** Itsuki in the 2 part OVA.
* DudeLooksLikeALady: Jun, with his long hair and soft, feminine features. Also extends to Jun in the live-action version, where he is played by actor and model Yuuki Ogoe.
* EveryoneCallsHimBarkeep: The Marionette King.
* FalseStart: for ''many'' 10 yard penalties.
* {{Fanservice}}: It's a Katsura comic; this is to be expected. PG-13 doesn't begin to cover it.
* FanserviceModel: Iori, who starts [[SwimsuitScene appearing in bikini only]] and then she becomes a gravure idol. Also Itsuki when she poses for art students.
* FirstGirlWins: Played with. Iori is the first girl we meet[[spoiler:, and she does indeed win]]. However, Itsuki is the first girl Ichitaka meets[[spoiler:, and she turns out to be the UnluckyChildhoodFriend]].
* FirstKiss: This is a romance, so several characters have it throughout the course of the story.
* FullyClothedNudity: Itsuki uses this while posing for some art students. Ichitaka freaks out because he thinks she ''is'' naked.
* GayBestFriend: Jun is one for all the characters, but it particularly shines with him being a RomanticWingman for Ichitaka.
* GenkiGirl: Itsuki, Izumi, and Nami sometimes come across this way.
* GirlNextDoor: Itsuki in the narrative sense (especially in flashback), Iori in personality (though not in looks), Aiko literally.
* TheGlomp: Itsuki & Izumi both do this to Ichitaka. [[http://manga.animea.net/i-s-chapter-98-page-16.html Iori is not above it, either.]]
* {{Gonk}}: The entire Teratani family.
* HardDrinkingPartyGirl: Nami is clearly this trope in-training.
* HighSchoolSweethearts: It's a romance comic. What do you expect?
* HotSpringsEpisode: Happens in the middle of the story, in the middle of the second BeachEpisode.
* IgnoreTheFanservice: Ichitaka with Izumi. She doesn't make it easy.
* ImagineSpot: Ichitaka regularly has daydreams about the women in his life, with a particular focus on Iori. It gets him in trouble more than once.
* INeverGotAnyLetters: Ichitaka agonizes that Iori may have forgotten about him while she is working on her theatre career because he never hears from her. [[spoiler:Her agent encouraged/convinced her to write letters instead of calling, and is tossing all her letters into storage instead of mailing them.]]
* InNameOnly: The first OVA, ''From I"s'', has almost nothing to do with the source material. The story is anime-original, it almost completely ignores Iori in favor of a childhood friend of Ichitaka and Itsuki's, changes the character designs to the point that they look like they're from a different series, and [[spoiler:features supernatural elements that are completely absent in the manga.]]
* IWantMyBelovedToBeHappy: Ichitaka often takes this stance towards Iori [[spoiler:One of his biggest issues is that he's very bad at telling what actually ''does'' make her happy.]]
** Also Itsuki, to the point that she [[PutOnABus goes to America]] to get her out of the way.
** There are a lot of indications that Jun also has a crush on Ichitaka. Since he knows his affection would never be returned, he does his best to get and keep Ichitaka and Iori together.
* IUhYouToo: [[spoiler:Iori's reaction to Ichitaka's confession.]]
* LastMinuteHookup: [[spoiler:Teratani and Yuka, though she's shown to like him much earlier in the story.]]
* LeaveTheTwoLovebirdsAlone: Duelling. Ichitaka, Iori, Teratani, and Yuka all go to a karaoke bar. Teratani is trying to get Ichitaka and Iori alone together, while Iori is trying to get Teratani and Yuka alone together. [[spoiler:The I"s have their LoveConfession, but Yuka is rejected.]]
* LethalChef: Itsuki is a slightly more mundane version – among other things, her scrambled eggs come out charcoal-like.
* LikeBrotherAndSister: {{Deconstructed|Trope}} with Ichitaka and Itsuki's relationship – he feels this way towards her while she nurses romantic feelings for him; when he finally starts to question if he does like her romantically, she realizes this trope is in effect and Ichi is just confused, and she gets over him.
* LoveAtFirstSight - Ichitaka when he first saw Iori. [[spoiler:Iori when she first saw him, apparently.]]
* LoveHurts: Does it ever.
* LoveMakesYouDumb: Ichitaka, You IDIOT!
* LoveMartyr: [[spoiler:Ichitaka breaks up with Iori because he doesn't want to be in the way of her dream to be an actress.]]
** [[spoiler:Iori breaks up with Ichitaka because she believes (not incorrectly) that her constant absence is making him miserable.]]
** Jun arguably is also this for Ichitaka.
* LoveTriangle: Ichitaka with Iori and pick-a-girl-whose-name-starts-with-an-"I" (or sounds like it in Aiko's case).
* LoveYouAndEverybody: Iori responds to Ichitaka this way on Christmas Eve in the karaoke bar.
* MagicSkirt: ''completely'' averted at every opportunity possible.
* MaleGaze: taken to a level that almost qualifies as an art form.
* MsFanservice: About the only girl who doesn't fill this role is Aiko. Mind you, much of the fanservice is via Ichitaka's ''active'' imagination.
** Nami serves as the in-universe example.
* ManipulativeBastard: Pretty much everyone who gets involved with Iori professionally, with her agent and her director most prominent.
* TheMatchmaker: Teratani is obsessed with this, to the extent that he completely ignores the one girl actually interested in him. Nami also does this for Iori.
** In the end, Nami ''literally'' shoves Yuuka's face against Teratini's [[BelligerentSexualTension so they will kiss already]].
* MistakenForCheating: [[spoiler:Iori at one point is worried that Ichitaka is cheating on her with Aiko.]]
* MomentKiller: Ichitaka is a magnet for these.
* MoodWhiplash: Whenever the Marionette King shows up, this romantic comedy jarringly becomes a suspense thriller [[spoiler:with the rather disturbing attempted rape scene(s) of 17 year old Iori.]]
** Then [[spoiler:again with The Marrionette King during the final chapters, when it takes a 5-page divergence from romantic dramedy to channelling the soul of ''Manga/HajimeNoIppo'' as Ichitaka breaks said King's kneecap and probably jaw in order to save Iori.]]
* NoGuyWantsToBeChased: Izumi ''aggressively'' pursues Ichitaka. Itsuki to a lesser extent.
* ObliviousToLove: Ichitaka to Itsuki's crush. Also, [[spoiler:Ichitaka and Iori to each others' crushes.]]
** Teratani to Yuka's crush.
** Likely Mr. Higemi to Jun's crush.
* OnlyKnownByTheirNickname: The Marionette King, who goes nameless in his first two appearances (despite the fact that he's in the same school as the characters, and they either know his name or could easily find out) and only gets known by his screen name in his final appearance.
* PantyShot: Way too many to count.
* PleasePutSomeClothesOn: Ichitaka to Izumi. She is reluctant to comply.
** Much earlier, Ichitaka says this nearly word-for-word to Itsuki after she shows up (jet-lagged) wearing only her underwear.
* PutOnABus: Itsuki short-circuits the love triangle early on when she leaves for America. [[spoiler:Aiko does not appear again after her arc concludes.]]
* RapeAsDrama: [[spoiler:Iori is nearly raped twice, both times by the same guy.]]
** In the 2 Part OVA, both Itsuki and Iori are targets of this.
* RescueRomance: Ichitaka's best moments generally involve him stepping in on Iori's behalf when she's having some sort of problem.
* RomanticFalseLead: It's revealed that [[spoiler:Iori sees Itsuki this way.]] Jun also very briefly functions as one, before it's revealed that [[StraightGay he's not into women at all]].
* RomanticWingman: Both Teratani and Jun regularly are there to assist Ichitaka with his fumbling romance with Iori. However, Teratani is significantly less helpful (and more lecherous) than Jun. While not shown nearly as often, Yuka is one for Iori.
* SceneryPorn: Aside from the lovely ladies we mean.
** The Three Gates Shrine
** The Christmas Tree
* SecondActBreakup: Happens at least twice.
* SecondLove: Ichitaka had a crush on a girl in the 6th grade before he met Iori.
* SecretRelationship: Iori's agency requires her to keep her "taken" status under wraps – [[TruthInTelevision This is actually standard operating procedure in Japanese entertainment circles.]]
* SheIsNotMyGirlfriend: Ichitaka regarding Itsuki.
* SlasherSmile: [[http://www.mangareader.net/1580-49082-14/is/chapter-48.html The]] [[http://www.mangareader.net/1580-49083-5/is/chapter-49.html Marionette]] [[http://www.mangareader.net/1580-49175-9/is/chapter-141.html King.]]
* SnowMeansLove: [[spoiler:Ichitaka confesses on Christmas Eve, as it starts snowing. It's also snowing during the climax a couple years later when Ichitaka keeps The Marionette King away from Iori.]]
* SoBeautifulItsACurse: Most of Iori's problems are inextricably linked to her being a first class super hottie.
* StalkerWithACrush: The Marionette King.
** Possibly Jun for Ichitaka in a very benign version. Ichitaka even {{Lampshades}} it a couple times, thinking how Jun often suddenly appears "like a ninja" when Ichitaka is upset, depressed, and/or wishing he had someone to talk to.
* StraightGay: Jun Koshinae - in fact, up until he comes out of the closet to Ichitaka, it appears like [[RomanticFalseLead he's interested in Iori]].
* StoodUp: Ichitaka, in one of his admittedly {{jerk|ass}}ier moves, insists Iori meet him in the park on their anniversary, despite her telling him she can't because she's busy rehearsing. He waits for awhile, but assumes this and leaves. [[spoiler:She shows up a few minutes later; he only realizes this after Aiko forces him to follow up.]]
* TechnicalPacifist: Jun.
* ThemeNaming: All of the romantic entanglements involve someone with the first initial "I"… with the exception of Aiko (and then, the first syllable of her name is pronounced like the letter in English).
* ThereIsOnlyOneBed: Iori and Ichitaka share a room, and bed, when staying at Teratani's relative's place. [[spoiler: They begin, but don't end up sleeping with each other.]]
* TookALevelInBadass: Both Ichitaka and Teratani whenever Iori is in trouble.
** By the end of the story, ''everyone'' has gone through badass level-grinding, as the flashback allows to compare.
* TrainStationGoodbye: Averted, thank goodness.
* TrueCompanions: Ichitaka, Iori, Teratani, Yuka, and Nami tend to hang and help each other out whenever they have free time.
** Jun soon joins as well.
* {{Tsundere}}: Itsuki, Izumi, and Nami.
* TwiceShy: The story is built on this trope.
* UnwantedHarem: Ichitaka starts acquiring one of a sort beginning halfway through the story, although he'd rather not. On the other hand, he's well aware of how attractive the unwanted girls are. At one point, he thinks that ''Yuka'' has the hots for him as well, which then leads to him realizing that Yuka is also quite attractive.
* {{Uke}} - Jun, in a milder sense.
* WillTheyOrWontThey: [[spoiler:TheyDo, two-thirds of the way in. From that point on the problem becomes ''staying'' together.]]
* WildTeenParty: Nami considers this a rite of passage, so she intentionally tries to make it happen. Several times.
* YamatoNadeshiko: Iori, especially early on. Despite her MsFanservice looks and her fame, she remains a kind and polite Japanese school girl. At one point she wore a very formal kimono, and looked pretty good in it.
* ZettaiRyouiki: Part of the school uniform.
