A list of characters of ''LightNovel/DenpaOnnaToSeishunOtoko''.

!Makoto Niwa

->'''Voiced by:''' Creator/MiyuIrino
The protagonist and a 16-year-old high school boy who has transferred to Meme and Erio's home city a year prior to the start of the story, due to his parents' work.
* AgentScully
* CloudcuckoolandersMinder: to Erio and a lesser extent to Meme
* DeadpanSnarker: Does this often, mostly in response to one of the girls being weird.
* FirstPersonSmartass
* GenreSavvy
* InSeriesNickname: He is still known as "Tenkousei" (NewTransferStudent) a full year after his arrival.
* InnerMonologue: In compliance to a long-standing Creator/StudioShaft tradition, he engages in this a lot.
* LikesOlderWomen: ZigZagged in several different directions. On one hand, Makoto seems to be attracted to both girls his own age as well as Meme, who is 23 years his senior. On the other hand, he tends to ping-pong between attraction and repulsion towards Meme.
* NewTransferStudent: At least one year ago.
* NiceGuy: For the most part. He has no hidden agendas while trying to help Erio open up despite what Yashiro may try to tell him.
* NotSoAboveItAll: In episode 3, after Meme leaves his room, the first thing he does is look outside the hallway to make sure no one's there. Then he jumps on his bed and sniffs his pillow where she was laying moments before. She then opens his door and tells him she probably doesn't have much of a scent because she wasn't wearing makeup.
* OnlySaneMan: Although he has his fair share of FirstPersonSmartass monologues.
* SecondYearProtagonist

!Erio Touwa

->'''Voiced by:''' Asuka Oogame
Makoto's hitherto unknown cousin and Meme's daughter, who happens to be a very strange girl with a fascination for [=UFOs=].
* AgentMulder
* BrokenBird: She claims to have lost half a year's worth of memory, broke her leg trying to fly while on a bike, talks about aliens and eventually earns a reputation to the point that she eventually becomes a recluse.
* ButNotTooForeign: She is half-Scottish
* {{Cloudcuckoolander}}
* CreepyMonotone: Noticeably loses it when Makoto forces her to admit she's a human being.
* CurtainsMatchTheWindow
* TheCutie: Just [[http://img4.sankakustatic.com/wp-content/gallery/safe-ix/denpa-onna-to-seishun-otoko-first-episode-image-gallery-002.jpg look]] [[http://fabien.li/tvtropes/Denpa%20Onna%20to%20Seishun%20Otoko%20-%2005%2011.57.jpg at]] [[http://fabien.li/tvtropes/Denpa%20Onna%20to%20Seishun%20Otoko%20-%2005%2013.52.jpg her!]]
* DoesNotLikeShoes: She not only looks and behaves like she came from another world, she actually ''thinks'' she's an [[HumanAliens alien]]. Therefore, it's safe to assume that she doesn't will to try such an invention of the humanity as shoes, not even after some of the illusions of her being an alien were broken.
* DoItYourselfThemeTune: Her voice actress performs the opening theme, ''Os Alien'', with Shinsei Kamattechan.
* HairAntennae
* {{Hikikomori}}: As much as it's PlayedForLaughs, Erio is a textbook case, reacting to severe trauma by withdrawing from the world. The fact that Makoto looks confused and sasses her instead of [[BystanderSyndrome pointedly ignoring her]] like ''everyone else in her life does -- her mother included --'' is getting her to open up to him, slowly.
* MagicSkirt: Considering how often the camera follows a low angle MaleGaze around her, Erio is lucky for this. There was a pretty unavoidable PantyShot in the first episode, but it was censored with a flying saucer.
* MulticoloredHair: Erio has very light blue hair but at times gains crystal-like glitter (that can flow off her without ending). Other characters notice this, mainly Makoto, but never mention it out loud.
* NoSocialSkills
* TheOphelia
* RapunzelHair
* ReiAyanamiExpy: Sparkling blue hair, pale skin, shy and very weird.
* SecurityBlanket: She finds it difficult to interact with people without having herself wrapped securely in a futon. Even after getting over the worst of this she finds it soothing.
* ShrinkingViolet: Social interaction-wise, after Makoto finally breaks her shell.
* ShyBlueHairedGirl
* TheoryTunnelVision: Erio was in a tragic accident wherein she went missing for three months and then turned up on a beach without any memory of the intervening time. Her reaction was so bad that she invented a story that she had been abducted by aliens and convinced herself that was the only explanation. After a few months, she tried to test her theory... only be injured ''again''. But again, because she was far too fragile to face reality, she only drew even further into her fantasy world, to the point of becoming a {{Hikikomori}}. Later, her cousin forcibly proves to her that she isn't an alien, but after an initial highly negative reaction, she seems oddly okay and is even willing to regain society again.
* TokenMiniMoe
* WomanInWhite: Erio often wears a lacy white, sleeveless dress (when she isn't wrapped in a futon, that is). This is to represent her unearthly beauty and pure, childish personality.
* TheXenophile
* YouGottaHaveBlueHair: That sparkles.

!Meme Touwa

->'''Voiced by:''' Creator/AiNonaka
Makoto's 39-year-old aunt and Erio's mother.
* AbusiveMom: PlayedForLaughs with her relationship to Erio. Thankfully it doesn't last very long.
* ChristmasCake: Played with, already being a 39-year-old single mother who still hits on her nephew.
* {{Cloudcuckoolander}}: Like mother, like daughter indeed.
* HairAntennae
* LargeHam: She tends to do this from time to time, such as when she decides to be the coach for the baseball team Makoto plays in.
* MumLooksLikeASister: She bore Erio at the marriageable age of 25, but still, would you believe that she's [[OlderThanTheyLook pushing forty]]?
* MrsRobinson: It's part of her complex about getting older and acting childish; she's constantly shamelessly flirting with Makoto (and everyone else).
* MsFanservice: Due to all the teasing she does to Makoto, and the sometimes revealing outfits she wears.
* OlderThanSheLooks: Seriously, Meme ''is'' thirty-nine (later forty) years old with [[AbsurdlyYouthfulMother that hot body of hers]]?
* OneOfTheKids: Thinks and acts very much like her daughter's age.
* ParentsAsPeople: Meme ''does'' love her little girl, and the only time she's ever been shown to be serious was when she's thinking about her, but that doesn't stop her from showing she has absolutely '''no''' idea on how to be a parent.
* RapunzelHair
* TheTease: Loves to utilize this on Makoto, much to his chagrin.
* YouGottaHaveBlueHair: Darker in tone than Erio's.

!Ryuuko "Ryuushi" Mifune

->'''Voiced by:''' Creator/EmiriKatou
Makoto's highly energetic classmate and a member of their school's girls' basketball team.
* ClingyJealousGirl: Shows no reservations on expressing jealousy whenever Makoto hangs around with another girl in her presence. She will also invite Makoto to events, only to suddenly change plans whenever she sees or learns that Erio is tagging along.
* CovertPervert
* CuteButCacophonic: Don't let Ryuuko cheer for you unless she's standing a good 20 or so feet away. Her "cheering" of Makoto involves her screaming into his ear at the top of her lungs.
* CuteLittleFangs
* GenkiGirl
* RedEyesTakeWarning: Subverted, in that she's a genuinely bubbly kid.
* SweetTooth: Fruits to be exact, having confessed of being a vegetarian.
* {{Tsundere}}: Pretty far to the deredere side, but it does emerge when she becomes a ClingyJealousGirl


->'''Voiced by:''' MaiFuchigami
Another classmate of Makoto who is unusually tall for her age.
* CosplayOtakuGirl
* HugeSchoolgirl[=/=]StatuesqueStunner: She tells Makoto that at 179.9cm, she is a magnet for school clubs, but due to her poor physical health (probably just being out of shape), they quickly lose interest in her.
* ShesGotLegs: Due to being so tall. Its most pronounced when she's wearing her various cosplay outfits.
* TheTease: While not as much as Meme, she does occasionally invoke this trope, particularly when Ryuuko is around.
* ThirdOptionLoveInterest: After Ryuuko and Erio.

!Tamura aka "Granny"

->'''Voiced by:''' Hiroku Maruyama
The old woman who owns the local sweet shop and employs Erio. A strong believer in aliens, who is convinced that she is being subjected to "cattle mutilation," causing her various illnesses. [[spoiler: She is also Meme's grandmother.]]
* CloudCuckoolander
* CoolOldLady
* IncurableCoughOfDeath: she's apparently been ill at least since Meme's childhood.
* MiniatureSeniorCitizens

!Yashiro Hoshimiya

->'''Voiced by:''' Creator/YukaIguchi
A mysterious girl who is frequently seen on a spacesuit.
* [[spoiler:ButNowIMustGo]]
* HairDecorations: A sun-shaped hairclip.
* MysticalWhiteHair
* MysteriousWaif: While Makoto treats her like a runaway brat, enough strange things occur when she's around to fit this trope, such as wearing a spacesuit in the middle of summer, along with some [[MaybeMagicMaybeMundane other strange coincidences]].
* OracularUrchin: Argues for the existence of the supernatural long after Makoto punctures Erio's fantasies. At points, she almost comes just short of convincing Makoto himself that perhaps life isn't as ordinary as it appears.


->'''Voiced by:''' Creator/YasunoriMatsumoto
Meme's childhood friend, who has returned to his hometown and now spends most of his time launching bottle rockets from an old baseball field.
* AccidentalMisnaming: Meme persists in calling him "Yamamoto," even after he tells her that isn't his name
* UnluckyChildhoodFriend: [[spoiler: When he returns to town after a few years, he immediately asks Meme to marry him. She immediately rejects him.]]


->'''Voiced by:''' Creator/TakahiroMizushima
A blonde boy Makoto meets while playing baseball.
* LoveConfession: Did one to Ryuuko before the start of the series, only to be turned down. This causes some awkward moments when she sees him playing on the town's baseball team, and he in turn shows up at her basketball game -- even as he is already dating Hanazawa.


->'''Voiced by:''' Creator/KanaHanazawa
Captain of the local softball team.
* TheAce: The shopping district team, and Makoto especially, are terrified of her pitching skills
* TheDanza: Only Creator/StudioShaft would name a character after [[Creator/KanaHanazawa her voice actress]].
* {{Determinator}}: While she was winning the preseason games between the city and shopping district baseball teams, she mentions to Makoto that they're constantly losing in the high school games. However, she mentions that she doesn't want to give up, unless their team just loses hope altogether and then possibly get disbanded due to lack of interest from students joining due to their poor track record.
* FriendlyEnemy: She is the ace pitcher of the opposing team to the RagtagBunchOfMisfits that make up the shopping district team, yet is never portrayed as anything other than nice and polite to Makoto, Maekawa, or anyone else from the other team who interacts with her.
