Tropes pertaining to the cast of Manga/OyasumiPunpun.

-----
!!'''Punpun Punyama/Onodera'''
[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/thank_u_based_punpun_4734.jpg]]
The main character of Oyasumi Punpun. Initially depicted as a vague, childlike drawing of a bird, Punpun is very optimistic and serious as a child. He falls in love with a girl named Aiko, and his promise to her to go to Kagoshima becomes his drive for the remainder of the story.

* BrokenBird: [[StealthPun Literally.]]
%%* CantHoldHisLiquor
* DespairEventHorizon: Punpun reaches it after [[spoiler:killing Aiko's mom]].
* DidNotGetTheGirl: [[spoiler: Aiko ends up hanging herself]], and after the timeskip the state of his relationship with [[spoiler:Sachi]] is ambiguous.
* DrivenToSuicide: [[spoiler:Attempts this by stabbing himself in his injured eye in the final chapters]]. [[spoiler:Luckily, he doesn't succeed, as Sachi saves him at the last moment]].
* EyeScream: Aiko stabs him in the left eye with a fork after [[spoiler:fleeing the scene of her mother's murder]]. She stops herself, though.
* IMissMom: [[spoiler:Averted. Punpun never liked his mother, and even after she gets cancer, apologises to him for all that she did, and dies, he still can't bring himself to love her.]]
* {{Jerkass}}: While he starts off good-natured, he slowly becomes more antagonistic to others as time passes. This culminates during his young adult age, where he becomes an all-round abusive jerk.
* KingOfAllCosmos: The God Punpun summons whenever he is stressed and in need of advice. He's... [[{{Understatement}} kind of weird.]] [[spoiler:He reveals later on that he knows that this "God" is really just him speaking to himself.]]
* NonStandardCharacterDesign: Starts out as a bird, [[ArtShift and from there changes into several different forms]]. No one ever comments on his strange appearance, implying that the Punpun we see is actually a reflection of his feelings.
%%* TheQuietOne
* SilentProtagonist: PlayedWith -- Punpun communicates with others just fine, though his speech is depicted in black narrative boxes instead of the standard speech bubbles, which serves to add to his detachment from others. [[spoiler:He finally speaks with speech bubbles in chapter 144.]]
%%* TroubledChild

!!'''Aiko Tanaka'''
[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/aiko_tanaka_3967.jpg]]
The transfer student from Punpun's elementary school, and his crush. She takes a quick liking to him and they become good friends for their time in elementary school.

* BeautyIsNeverTarnished: Averted. In later chapters, she gets a bruised eye, a missing tooth, and several bloodstains on her face; she also has several bruises on her shoulders.
* BrokenBird: Just as bad, if not moreso, as Punpun. Her crippled mother abuses her physically, emotionally, and verbally, and forces her to take part in her cult.
* ContinuityNod: She bites [[spoiler:Punpun's]] finger so hard that her front tooth comes out, making her look like she did when they first met.
* DrivenToSuicide: [[spoiler:She is found to have hung herself in chapter 139.]]
* HairColorDissonance: Canonically has [[http://38.media.tumblr.com/c42e377e19432b2c00fc9dedc1eca1b0/tumblr_n9skgbL5B51s6w5tao1_1280.jpg brown hair]], but the majority of fans depict her with red hair instead.
* ManicPixieDreamGirl: Invoked by Punpun. Is horribly, horribly deconstructed in later chapters.
* PutOnABus: She becomes scarce after Punpun enters middle school, and by the time they're in high school, she's nowhere to be found. [[spoiler:She comes back a short while after Punpun leaves high school and moves into his own apartment]].
* StepfordSmiler: The depressed type of Stepford Smiler; although it's noted by several characters that she's bad at faking a smile.
%%* TroubledChild
* YouGottaHaveBlueHair: One of the [[http://img.batoto.net/comics/2012/12/25/o/read50d978e0c361c/img000023.jpg colour spreads]] in volume 11 gives her black-green hair, or at least black hair with green highlighting.

!!'''Sachi Nanjou'''
[[quoteright:225:http://static.tvtropes.org/pmwiki/pub/images/sachi_2079.jpg]]
An aspiring manga artist who Punpun eventually becomes involved with.

* AuthorAvatar: Seems to be one for InioAsano, to a degree. They're both mangaka, and many of the beliefs she espouses towards making manga seem to reflect Asano's own philosophy on writing manga. The manga she eventually makes also appears to be Solanin.
* CannotSpitItOut: She's a bit too proud to straight up tell Punpun how much he means to her.
* GoodGirlsAvoidAbortion: She gets pregnant by [[spoiler:her ex-husband]], and initially plans on getting an abortion, but decides to keep the child in the end.
* JerkWithAHeartOfGold: She's very abrasive, frequently delivering TheReasonYouSuckSpeech to Punpun, but she cares about him all the same and is a good person all around, just a bit rough around the edges.
* LastGirlWins: She's the last prominent female character Punpun meets, and is eventually the one he ends up with, though the specific status of their relationship is ambiguous.
* ManicPixieDreamGirl: Downplayed. She's fairly bright and optimistic and helps to bring out the best in Punpun after [[spoiler:the funk he's in brought by Azusa's TheReasonYouSuckSpeech]], encouraging him to work harder, and the two become romantically involved.
* VitriolicBestBuds: Is this with Miyuki.
