Clingy Jealous Girls in Visual Novels.
- Rizu in A Profile as a result of trauma was extremely clingy with Masayuki in the backstory. Though she's better now, she's largely responsible for screwing up a large amount of his relationships... and she knows it too.
- Elis in Canvas 2 gets very jealous whenever Hiroki shows interest in anyone apart from her. Except for one case where she feels completely outclassed by her 'opponent.'
- In CLANNAD, after drinking one cup of sake, Nagisa becomes this in regard to her own mother. Sanae gets drunk and fuels the whole thing further as well. Needless to say, Hilarity Ensues.
- Averted with Amanda early on in Daughter for Dessert. Even though she’s smitten with the protagonist, and has been since she was a small girl, she doesn’t even seem to be affected when she walks in on him having sex with someone else (Heidi or Veronica, depending on player choice). It’s played straighter later on, when Amanda gives the newly hired Lily trouble in her job. This change is justified, as by this point, the two of them are more or less official as a couple.
- Doki Doki Literature Club!: Monika is typically peppy and outgoing, as President of the eponymous Literature Club, but behind the scenes she earns her reputation as one, after she is implied to have subtly gaslit Sayori and Yuri into committing suicide so she could claim the MC for her own. She even goes as far as to UnPerson Yuri and Natsuki by hacking their character files as an in-universe way of enforcing Deletion as Punishment on the other girls competing for your heart. She will have you, and only you. If she has her way, you will have just Monika.
- Johanna and Tamara from Double Homework both have shades of this. Due to their personality differences, it shows up in different ways, with Johanna retreating for a long period of time, and then unconvincingly saying that she’s not upset, whenever the protagonist shows interest in someone else, and Tamara actively sabotaging his relationships with other girls, and dating Dennis just to get back at him. They eventually put aside their differences and decide to share him among themselves.
- Even after kicking her fiancé out, Bethany from Melody turns out to be this eventually. She tracks down her ex at his new home, and resorts to threatening to sabotage Melody’s career in order to coerce him to come back to her.
- Pearl Fey from the second and third Phoenix Wright: Ace Attorney games fits this trope. She's jealous not for her own sake, but for her cousin Maya, whom she's convinced is romantically involved with Phoenix. She will not hesitate to slap Phoenix up and down if he fails to be sufficiently romantic (which is often).
- Touko in Suika, to a rather disturbing extent.
- Akiha Tohno of Tsukihime tends to not trust any woman Shiki associates with, but that's normal jealousy, not clinging...except during Kohaku's storyline, where she deals with Shiki's rejection rather violently. She was, admittedly, not herself at the time.
- Outside of the original Visual Novel, however, Akiha more firmly falls into this trope. Shiki's awareness of this seems on-and-off, but it's illustrated rather poignantly in Kagetsu Tohya, when a minor (female) character is reduced to near-incoherent terror at the thought of being seen with Shiki by Akiha. Poor, poor Seo...
- In Ciel's route in the VN both Arcueid Brunestud AND Ciel become this, just to give an idea about how bad Arcueid gets. In this route you learn why Arcueid is so infamous when she sits back and lets Shiki's mind get raped for a while so she can use it as leverage to make him her servant so that he'll have to be by her side for the rest of his life. Plus all the evil glares, or what happens if she is rejected (True End).
- Sakura Matou in Fate/stay night exhibits some of these tendencies, particularly in her own route, and especially when the potential rival is Rin Tohsaka. She does, at least, have a pretty good explanation: her lack of self-worth leads her to not really understand that Shirou likes her for who she is, and she's constantly scared that he'll fall for some other, "better" girl and leave her alone. Due to her personality, all she really does is go rather cold and quiet whenever Shirou's being friendly with another girl.
- Mizuhara in Kara no Shoujo has a borderline yandere fixation on Toko, meaning that while Reiji is one of the few people or things she claims not to hatenote she is always very hostile towards him. Ends up getting Toko hit by a truck.
- As mentioned above, both Sekai and Kotonoha are this in School Days. Also Otome: she already bullied Kotonoha alongside her Girl Posse, but the bullying increased thousandfold when Kotonoha became one of Makoto's love interests.
- Hanako Ikezawa shows some slight tendencies of this in Katawa Shoujo. She's too sweet and shy to fit the trope completely, but she is shown to become anxious whenever Hisao looks at or spends time with other girls or women. Her anxiety is somewhat understandable because despite his feelings for her and them growing close, Hisao doesn't actually show any signs of attraction towards Hanako until the very end — ironically, out of fear of scaring her off. Her anxiety over losing Hisao to someone else- her best friend Lilly, whom she feels is more attractive, and even the route-less Yuuko- ultimately causes her to initiate sex with him, despite neither of them being emotionally ready for it yet.
- Kindred Spirits on the Roof:
- Megumi Nagatani is one of the two "kindred spirits," and has been in a relationship with Sachi Enoki since Megumi died 30 years before the start of the game. She sometimes shows hostility towards Yuna Toomi, the protagonist, since Yuna is the first person they know of who can see the kindred spirits and thus the first potential competition Sachi has had in 30 years. The fact that Sachi often spends time alone with Yuna, in places Megumi can't go, doesn't help matters.
- Downplayed with Miyu Inamoto, vice-captain of the team and Matsuri Amishima's girlfriend. She never shows hostility toward her rivals in love, but Matsuri's popularity with other girls makes her feel a bit insecure.
- A minor case with Sasa Futano, a member of the broadcasting trio who's Umi Ichiki's girlfriend. She gets rather annoyed when Youka Koba addresses Umi by her first name without an honorific, something only Sasa and Nena Miyama(Umi and Sasa's mutual friend) do, although Youka is practicing to do the same for the girl she likes.
- Yukino in My Girlfriend Is the President. The only thing that can make her really angry is somebody taking Junichiro away from her. At one point she bans exports of Junichiro to prevent Putina from taking him to Russia.
- In My Harem Heaven is Yandere Hell, Yuuya has three yandere girls, only this time, all of them are childhood friends. Their descent into darkness is a result of them getting jealous of Kayoko kissing Yuuya.
- In Mystic Messenger, the female Player Character can act like one towards Zen and/or accuse Jaehee of being one on Zen's route; several possible choices on his route have her say that she spent all day thinking about him, want to own him, think Jaehee's just a jealous bitch for being against her getting romantically involved with Zen, and even act like she nearly died from not being able to chat with him for a few hours. However, doing this will harm Zen's opinion of the main girl and very likely put her on track for getting a bad ending with him.
- Mari in the Parascientific Escape series is this to her boss, Kyosuke. She firmly believes she's his future wife, and nothing will dissuade her from this. In the Good Ending, she's right.
- Drakan from Sable's Grimoire is a half-dragon and on her own route ends up applying the same mindset that results in Dragon Hoards to her budding relationship with the protagonist Sable.
- Shinrai: Broken Beyond Despair has Momoko "Momo" Mori, act this way toward her boyfriend Hiro Shiratake. She becomes very hostile toward Runa Hikari, who loves Hiro, when she sees Runa trying to talk to Hiro, and also suspects that her best friend, Kamen Eiga, wants Hiro to herself(Kamen is actually a lesbian who loves Momo and hates Hiro), threatening to break off their friendship if Kamen persists. When she discovers texts from Hiro on Kamen's phones, she plots to murder Hiro and frame Kamen for the crime. Hiro ends up getting sick of her attitude, and passive-aggressively mocks it with a horror story about a similar girl, whose clingy, controlling attitude and refusal to let her boyfriend be with anyone else resulted in her killing him with a knife before hanging herself. The argument was staged as part of their plan for a prank (which Momo used to kill him), but it was based on an actual argument. The trope ends up being deconstructed, since this aspect of Momo's character is shown to be the product of her trust issues, since she was often taken advantage of in the past.
- Many of the supporting girls in Shiny Days are truly awful with their jealousy, particularly Sekai, Karen and Otome. They lie, abuse others, manipulate Makoto, steal and betray their friends with no hesitation and without consequence. Their level of entitlement is truly scary.
- Yoshio Saotome's younger sister Yumi, from Tokimeki Memorial. Not only she's one of the girls who'll fall faster for the main guy (as well as the youngest, meaning she's more immature than the rest), she also can "bomb" him very easily out of envy (meaning, their relationship will go sour and all the other girls will lose interest in him) and has a special event triggered by seeing the local Supreme Chef, Saki, sharing her food with the boy.
- Also Minori Akiho... towards Saki.
- And in Tokimeki Memorial 2, Hikari, and when she's in love with the protagonist, Mei (leading to an Event - appropriately named "You are my 'only' slave" - where she delivers the quote on the main page).
- Also, Miyako from Tokimeki Memorial 4. Who even goes the Yandere route.
- Mikae Morikawa from True Love Junai Monogatari. She doesn't go after the girls for catty revenge, thankfully, but she takes her jealousy on the MC. A lot. And please, please don't make her think that you're leading her on. PLEASE.
- In Yandere, Subaru is surrounded by three Yandere girls: his Childhood Friend, his Hot Teacher, and a Shrinking Violet underclassman. Towards the end of the visual novel, all three love interests start acting creepy and possessive. What happens to him and who he gets will depend on his choices.
