Line #32 Characters/MysteriousGirlfriendX


1	!Akira Tsubaki
2	->'''Voiced by:''' Creator/MiyuIrino (Japanese), Creator/JoshGrelle (English)
3
4	The main male protagonist. Since he tasted Urabe's drool, the two have entered into a strange love relationship.
5
6	* AccidentalPervert: Rare for a manga/anime romance protagonist, he only gets a couple of these incidents on his record. Akira also outright averts this when he trips and is about to fall onto Urabe in her apartment, where he deliberately causes himself to fall into her bedpost instead.
7	* ChivalrousPervert: In spite of his teenage libido rearing its head when Urabe is around, Akira never lets it override his morals or cause him to hurt his girlfriend. His resolve does waver when especially erotic situations arise, but that's to be expected at his age.
8	* MyGodWhatHaveIDone: Has a brief moment of this when he comes on a little to strongly towards Urabe which causes her to tear up, really just her own AggressiveSubmissive behavior rearing it's head. Thinking he pushed past her comfort zone, he actually retreats from their relationship until Urabe clears the air.
9	* NiceGuy: Akira is a genuinely nice guy who, while sometimes confused about Urabe's mysterious ways, does his level best to treat her right.
10	* RidiculouslyAverageGuy: He doesn't excel at anything in particular, being a pretty average Japanese teenager in all regards.
11
12	!Mikoto Urabe
13	->'''Voiced by:''' Ayako Yoshitani (Japanese), Genevieve Simmons (English)
14
15	The main female protagonist. A ''really'' weird girl who enjoys cutting things up with her "panty scissors".
16
17	* AdjectiveNounFred: Urabe's the eponymous Mysterious Girlfriend X for which the series is named after.
18	* AggressiveSubmissive: While she prefers to maintain control of how Akira can touch her, the one time she gets caught off guard sees her become suddenly submissive, which only stopped because he got ahold of himself.
19	* AmbiguouslyHuman: For the most part she seems like a typical (if unusual) teenage girl, but between her odd thought patterns, various saliva-based powers, and unexplored background it's not out of the question that there's something more to her. There may also be something to the fact that she is frequently surrounded by alien imagery.
20	* BeautifulAllAlong: She really starts turning heads in school just by getting a different haircut that lets her face be visible, getting this reaction from the boys in class. Akira gets rather jealous when boys start talking about how beautiful she is.
21	* ClingyJealousGirl: Urabe, in turn, gets rather jealous when Akira becomes a fan of the idol Momoka Imai and shows her the fanbook he bought. She calmly asks him what is his favorite picture is, waits for him to show it to her, then Urabe slices the entire book to pieces... even though Akira only likes the idol since she reminds him of Urabe.
22	* CloudCuckooLander: Unsurprisingly, Urabe is a rather bizarre girl, albeit a more focused example than most. She clearly thinks in a far different way than most around her, and habitually keeps a pair of scissors hidden on her underwear as a weapon. Putting aside the whole "psychic powers via saliva" thing, she gets this reputation on the first day of school by having a laughing fit in the middle of class.
23	* CovertPervert: She has a lot of self control, but she admits that she's just as perverted as Akira. Part of this is helped along by how she refuses to let Akira notice when she gets affected by his saliva or when he shows up in her dreams.
24	* DefrostingIceQueen: At the beginning, Urabe is cold and aloof to the boy that she ''knows'' she'll lose her virginity to, but she warms up to him as they establish a bond of love and trust.
25	* DoubleStandardAbuseFemaleOnMale
26	* EyesOutOfSight[=/=]HidingBehindYourBangs: Urabe's signature hairstyle covers both or later one of her eyes most of the time, conveying her oddball mysterious nature, with both eyes only being visible when she's making a point or being serious.
27	* HatesBeingTouched: A major BerserkButton for Urabe is Akira attempting to hug her without Urabe's prior permission, at which point something of his will be getting sliced to ribbons.
28	* HeterosexualLifePartners: With Oka, in spite of Oka also being addicted to Urabe's saliva.
29	** PowerOfTrust: They even have no problems giving their boyfriends erotic picture with both of them in bikinis. Although Urabe was hesitant at first.
30	* HiddenBuxom: Although less evident through her clothes, Urabe has pretty big breasts for her age.
31	* MsFanservice: Together with Oka, they are the biggest suppliers of fanservice in the series.
32	* PolarOppositeTwins: Unrelated example with Momoka, seeing as they look like each other. Momoka is well-known for being outgoing and smiling frequently, whereas Urabe is reserved and stoic.

34	* ShearMenace: With a pair of hand scissors that she habitually carries, that she can BladeSpam with high precision.
35	* TheStoic: In comparison to Akira's excitable nature, Urabe is pretty unflappable and calm most of the time...
36	** NotSoStoic: Except when her boyfriend says something that really affects her or when his saliva has powerful emotions in it, in which case her facade cracks and shows that she's just as prone to embarrassment as he is... or when Oka tries to look up her skirt, or that time when Oka revealed she took a photo of Urabe when she was naked.
37	* SugarAndIcePersonality: Mostly ice in public and early on in her relationship with Akira, with the sugar coming up when Akira shows his love for her.
38	* {{Tsundere}}
39	* TsurimeEyes
40	* WhenSheSmiles: Her smiles are few and far between, but she usually blows Akira away whenever she does.
