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

And thus begins '''Ill Boy, Ill Girl''', a manga written by Creator/NisioIsin and illustrated by Akira Akatsuki, the pair's second team-up since ''Manga/MedakaBox''. The manga began in January of 2016 and underwent a monthly serialization in ''[[Magazine/ShonenJump Jump SQ]]''. It officially ended in April 2017, with its fourth collected volume printed in May.

!! This manga provides examples of:
* AbusiveParents: Implied to be the case for the girl, given how they’re known serial criminals.
* AmbiguousSituation: Because of how twisted the boy is, it’s unknown whether he was putting his plan into action and stabbing the girl to death or if she died of the disease and he’s just angrily stabbing her corpse.

* GivenNameReveal: The Boy and Girl's names, at the very end, are revealed to be [[spoiler:Shou Yamai in their obituary, [[OneSteveLimit having the same name]].

* GivenNameReveal: The Boy and Girl, at the very end, are revealed to be named [[spoiler: Shou Yamai in their obituary]].

* TheOnlyOneAllowedToKillYou: The boy pretty much has this feeling towards the girl. He’s not even going to let the disease kill her.

* LoveEpiphany: Just about the only concrete thing we got from the last volume's bonus chapter is this--the Boy and Girl are able to see each other because they are, on some level, the same dye to bith having the disease. When they start falling in love with each other and noticing each other as members of the opposite sex, this is represented by the other's words and face being covered up by their disease like everyone else. The Boy has this epiphany late in the story, but the Girl is revealed to have fallen for him after he threw the suprise party[[note]]And if you're wondering how she could recognize him and what he's saying, [[HandWave she's a genius]].[[/note]].

* MenAreTheExpendableGender: Discussed in the first chapter when the boy theorizes that if the girl dies before him, he’d become a footnote at best while everyone focuses on her death. we later learn that this won't be the case--[[spoiler:as the daughter of two convicted criminals in addition to a popular target for assassination due to her extreme intelligence, everyone working at the hospital is confident that the Girl won't be missed or sought after by the outside world. True to form, when she finally dies, it becomes the talk of the evening news but nothing more than that.]]

** [[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 to 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.]]

* DangerousSixteenthBirthday: According to hypothesis, the expected death date of the kids should be their twelfth birthday--the exact date. [[spoiler:While the Girl doesn't get to prove this hypothesis since she was killed a few days before hers, the Boy dies on his birthday.]]

* MenAreTheExpendableGender: Discussed in the first chapter when the boy theorizes that if the girl dies before him, he’d become a footnote at best while everyone focuses on her death. This ends up not being the case, as we later learn--[[spoiler:as the daughter of two convicted criminals in addition to a popular target for a hit due to her extreme intelligence, everyone working at the hospital is confident that she won't be missed or sought after by the outside world. True to form, when she finally dies, it becomes the talk of the evening news but nothing more than that.]]

* 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. However, the story does have certain characters who are very unique that are treated the same by the Boy's disease, showing that the "individuality" that the Boy craves is much more than physical appearance. By the end, 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; and she's so advanced for her age and so forward for her time that people were planning on killing her before she had a chance to really change the world. 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.]]

* CondescendingCompassion: Chapter 3 has the Boy play a game of Shogi with the Girl and win, only to find out indirectly that the Girl is a child genius and very likely [[ILetYouWin win the match]] to make him feel better about himself. Pissed and hurt by the idea, he makes her own up to that and asks her to come at him with her full prowess-- and while he gets stomped immediately, he does feel a little better.

* {{Expy}}: It's easy to see the Boy and Girl as a child sized and terminally ill [[Manga/MedakaBox Zenkichi and Medaka]], especially since both writer and artist worked on ''Medaka Box'' bot long before this manga.

* {{Foil}}: The boy and the girl have contrasting personalities. The boy is a jaded cynic and tries to use the disease as his own advantage for fame. The girl is more cheerful and upbeat despite having the same disease and her own background.

* GenkiGirl: The girl, despite being afflicted with a disease and having a very short life, is very chipper and peppy.

* MenAreTheExpendableGender: Discussed in the first chapter when the boy theorizes that if the girl dies before him, he’d become a footnote at best while everyone focuses on her death.

* SoapOperaDisease: Dangerous and makes you terminslly ill? Weakens your muscles? Makes it so you don't have long to live as a youth? This disease is all that and more.

* {{Expy}}: It's easy to see the Boy and Girl as a child sized and terminally ill [[Manga/MedakaBox Zenkichi and Medaka]], especially since bith writer and artist worked on ''Medaka Box'' bot long before this manga.
