History Manga / IllBoyIllGirl

* TheBigSleep: [[spoiler:How the Boy's death is played out. When he finally dies in Intensive Care, his eyes are closed with a peaceful expression while he is told "Good Night" (the Japanese text reads it as such, but the phrase itself was written as the character for "death").]]

* KillTheOnesYouLove: [[spoiler:The whole hospital was gearing up for the Boy to kill the Girl. When the Boy actually tries to make good on his plan, he only goes it because he's fully fallen in love with her and wants her t die as happily as possible. This trope could be subverted though, as it's not made clear if he actually ''killed'' her as opposed to her just dying.]]

* TalkingInYourSleep: This is what causes the boy to stop his first attempt at murdering the girl: she cries out to mommy and daddy to stop.

* TroublingUnchildlikeBehavior: Both leading children are far removed from ordinary children's mindsets. The Boy has an inferioroty complex so bad that he wants to kill the Girl to have a surefire shot at being immortalized through naming his illness and even made set days to attempt his kills, while the Girl is so intelligent that she hardly comes off as a normal kid.

* LampshadeHanging: In the last volume, the cast call upon few of the main complications in the plot, such as how everyone is sure the disease can kill upon reaching twelve years or how they can say no one person is unique unlike the protagonists when the whole ''point'' of the disease is to scrub a person's individuality from the affected's minds.

* ExactWords: Discussed. The disease was said to kill a patient on their twelfth birthday--which means, with a leap in logic, the disease won't ''allow them to die'' until their natural death at twelve. The idea is teased when [[spoiler:the Boy is pushed off the escalator and left to die, but suddenly wakes up as if nothing happened]], although it's unclear whether or not that actually happened.

[[caption-width-right:330:Your typical BoyMeetsGirl story... Except for the fact that they have a peculiar terminal disease.]]

* CentralTheme: Individuality. The disease the Boy and Girl share make it so any trace of individuality in a person is obscured, and the Boy in particular is obsessed with having it and initially lords his special circumstances over everyone else, even antagonizing the Girl for having overwhelming individuality. By the end, however, the series seems to come to the conclusion that "individuality" is more of a social construct than an objective truth, and trying to make yourself stand out is a wasted effort.

* ParodySue: The Girl has so much individuality, she's overwhelming. Her parents are serial criminals, her artistic sense and intelligence are off the charts, and her personality is gravitational; no one in the hospital can atop talking about her and even the Boy, who hated how special she was, couldn't help but fall in love with her. [[spoiler:She was even the cause of her parents going criminal, given they practiced to be able to kill her. But even with all of that, she ends up as nothing more than a footnote in medical history with the Boy as the namesake for their disease.]]

* TroublingUnchildlikeBehavior: Both leading children are far removed from ordinary children's minsets. The Boy has an inferioroty complex so bad that he wants to kill the Girl to have a surefire shot at bejng immortalized through naming his illness and even made set days to attempt his kills, while the Girl is so intelligent that she hardly comes off as a normal kid

* DrivenToSuicide: [[spoiler:The Young Boy and Rich Girl are made to look like the hung themselves a little after they arrived. In reality, they were both experimented on because they both claimed to have the disease.]]

* YourDaysAreNumbered: Both the boy and girl have until their 12th birthdays before they die from their disease. [[spoiler:Neither of them love in the end, but the girl never makes it to her 12th birthday, being killed a little before it.]]

* PunnyName: A doctor appears in the fourth chapter and gives the boy a vial of poison. He says to call him Doc, which when spoken in Japanese is similar to ''doku'', which is poison in Japanese.

* YourDaysAreNumbered: Both the boy and girl have until their 12th birthday before they die from their disease.

* PunBasedTitle: Wouldn't be a Nisio series without a pun somewhere. The title's actually pronounced "Shounen Shoujo" in Japanese,[[note]]The "Shou" in the title is written with the kanji for illness (症) rather than the kanji for youth (少)[[/note]] referring to both the nameless protagonists (who've pretty much been referred to as "I" and "That Girl" courtesy of the Boy) and their ailments.

* BitchInSheepsClothing: The girl. While she’s very happy and energetic, she manages to have her AxeCrazy tendencies.

* HowWeGotHere: The story opens up with the boy stabbing the girl. The only thing preventing this from being a ForegoneConclusion is whether or not she was already dead by the time he got to stabbing.

* NamelessNarrative: Given the premise of the manga, none of the characters in this manga are named.
* NoNameGiven: As per the nature of the manga, the only two people whose names and faces aren’t scratched out are people have no actual names given to them. In fact, the lack of a name for the disease is a plot point.

* PunnyName: A doctor appears in the fourth chapter and gives the boy a vial of poison. She says to call her Doc, which when spoken in Japanese is similar to Doku, which is poison in Japanese.
