Yukio: I love you so much I want to destroy any man who lays eyes on you...
Though the comic primarily revolves around Junko's and Yukio's antics and general love life, other characters have been introduced during the course of the series, resulting in various episodes focusing more on a specific background character and their backstory and personality.
The comic is mostly Slice of Life, but since it's written from the perspective of two completely insane stalkers, expect a lot of Psychological Horror and Fridge Horror to show up. With the addition of new characters, the story now dips into light Body Horror as well.
Compare to I Made A Comic About Internet Explorer, another twitter series by this duo.
Stalker x Stalker contains examples of:
- Ax-Crazy: Goes for pretty much every major character so far.
- Ironically averted with Takeshi, who is a delinquent, but hasn't shown any violent tendencies as of yet.
- Battle Couple: Junko and Yukio in episode 24.
- Big, Screwed-Up Family: Junko and her younger sisters Aiko and Airi are all characterized as Yanderes. Subverted in that their mother at least seems to be normal.
- Cast Full of Crazy: There's both Junko and Yukio of course, but then the latest pages introduced Aiko and Airi, a pair of sibling Yanderes with a crush on delinquent Takeshi, Hana, a girl so enamored with her big brother she'd do literally anything for him, and Hana's ,as of now, nameless older brother. To say that none of these characters are mentally well would be an understatement.
- Crazy Jealous Guy /Clingy Jealous Girl: Played straight with Junko and Yukio respectively.
- Curb-Stomp Battle: The fate awaiting every boy bold enough to flirt with Junko. Yukio is a lot stronger than he looks.
- Cute But Psycho: Junko can be quite adorable with her sincere devotion to her boyfriend - when she's not threatening him with murder for presumably cheating on her, that is.
- Entitled to Have You: Both Yukio and Junko believe the other belongs exclusively to them and react very badly to members of the opposite sex trying to engage with their partner.
- The Twins pressure Takeshi into dating both of them with the reason that they've "been in love with [him] since [they] came to this school."
- Evil vs. Evil: Hana's Mad Doctor older brother, who collects "trophies" from young girls he's killed, is revealed to have an interest in Junko.
- Fatal Attractor: Played straight with both Junko and Yukio, as they both attract a lot of attention from boys and girls respectively but neither of them is interested in sharing their partner with anyone.
- Four Eyes, Zero Soul: Yukio wears glasses and can be just as dangerous as his girlfriend Junko.
- Hana wears them too and is a girl willing to lure innocent people to their deaths for her brother.
- If I Can't Have You...: Junko would have pulled this on Yukio, had he rejected her.
- Aiko tells Takeshi she and her sister would be "really upset" if he refused to date them, all while she and said sister brandish a bat and a taser respectively.
- In Love with Your Carnage: Neither Yukio nor Junko particularly mind the others violent outbursts and tendencies. Quite the opposite, actually.
- The Twins' main reason for falling in love with Takeshi is that he's a delinquent.
- Insane Equals Violent: Played straight with Junko and Yukio.
- The twins are no different.
- Japanese Delinquents: Takeshi is a standart example, bleach-blond hair included.
- Loners Are Freaks: Junko and Yukio aren't particularly interested in spending time with anyone but each other and they're both clearly not sane.
- Love Makes You Crazy: It's never shown what Junko or Yukio were like before meeting each other, but it's safe to say their relationship hasn't done either of their mental states any favors.
- Possibly Averted with the Twins, as they show signs of an ambiguous mental illness even before meeting Takeshi.
- Love Makes You Evil: Played horribly straight with the two leads. Both of them are willing to do just about anything to keep the other by their side.
- Platonic example with Hana and her brother. Hana purposely befriends girls he's shown interest in, so he can get more "trophies".
- Mad Doctor: Hana's older brother, who is introduced in episode 21
- Mad Love: Airi and Aiko really like Takeshi, but whether or not he reciprocates is another matter entirely.
- Madness Mantra: Junko repeatedly chants "I love him [Yukio]" in her mind, in the very first episode. Talk about a memorable first impression...
- Murder the Hypotenuse: Junko at least has been shown to be responsible for the death of one of Yukio's admirers. Though there's little doubt Yukio wouldn't do the same.
- Nightmare Fuel Station Attendant: Junko's and Yukio's "flirting" can be extremely off-putting to everyone around them.
- No Social Skills: Junko is shown to be not very skilled at communicating with other people, not even with Yukio or her own mother.
- Nothing Is Scarier: It's never shown what exactly Junko does to the girls who come to close to Yukio, but given her "valentines gift" to him, it's probably better this way.
- Red and Black and Evil All Over: See Red Eyes, Take Warning below. Additionally, most of the Yanderes wear black clothing with some red highlights or accessories.
- Red Eyes, Take Warning: Almost all Yanderes in the story have black hair and red eyes.
- Sadist: Junko seems disturbingly chipper whenever she gets the opportunity to torture/kill a rival. In her first meeting with Takeshi, she gleefully muses about how she'll murder Yukio, should he ever cheat on her.
- Hana's older brother seems to be one.
- Stalker with a Crush: Junko and Yukio regularly stalk each other even after they get together.
- Something About a Rose: Junko wears a red rose in her hair at all times.
- Too Dumb to Live: Junko and Yukio are anything but subtle about the fact that they're dating and that they're violently possessive of each other, yet every few episode you've got some hapless idiot ignoring the obvious red flags and making a move on one of them. Three guesses how that usually turns out...
- Uncanny Valley Girl: Junko is a prime example of this trope.
- Same for Hana.
- Villain Protagonist: Downplayed. Junko and Yukio are far from good people, but as long as no one threatens to take their partner away from them they're fairly harmless.
- Woman Scorned: The comic heavily implies Junko would have stabbed Yukio to death if he hadn't accepted her confession.
