Ho Yay / Bakemonogatari

  • Bakemonogatari has Psycho Lesbian Suruga who is dangerously in love with Hitagi. So much so that she starts stalking Koyomi after he hooks up with Hitagi and tries to beat him to death twice. And then her later actions towards him are basically Straight Yay.
  • Tsubasa's descriptions of Hitagi during "Suruga Monkey", where she seems to trail off into deep thought as she says how beautiful Hitagi is.
  • There's a scene in episode 8 of the first series where Oshino walks up to Koyomi and leans in so close to him that their faces are a mere few inches apart. He's also pretty fond of Koyomi in general.
  • Karen and Tsukihi have this going on. Koyomi even calls them "the yuri sisters!"
  • When the Meddlesome Cat (a male apparition, in a girl's body) grabs Koyomi from behind, he licks his neck in a very sensual way. Though the Cat's tongue is also sharp enough to let out a jet of blood.
  • Karen fangirls over Suruga moreso than just normal athletic admiration, going so far as to constantly pester her older brother to introduce her to Suruga with suggestive outfits and the like. Koyomi refuses because he figures if he does so, it won't just be subtext anymore. Suruga's actually not that happy to see Karen, but she reacts to Karen as if she is a Stalker with a Crush.
  • Nekomonogatari (White) makes self-aware pokes at the trope, as Senjougahara starts making suggestive comments to Hanekawa out of nowhere while denying that they are in any way suggestive. They end up showering together (complete with Skinship Grope) and sharing a futon for the night.
  • In Otorimonogatari, Tsukihi lectures Nadeko on her unrequited crush towards Koyomi. Clearly it's meant to mean "try harder at it, or move on from him" but it comes across more as "quit thinking about my brother because I want you to go out with me". Being in matching kimono and getting dangerously close twice during this scene doesn't help.
    • The two actually have a load of subtext reaching back to their elementary school days; Tsukihi was Nadeko's Only Friend and has apparently remained so.
  • In Hanamonogatari, Numachi Rouka explicitly states that she is also a lesbian and asks Kanbaru if she wants to kiss, climbing over her and kissing her cheek instead. Later, something similar happens where Numachi ends up under Kanbaru after trying to defend against a slam dunk. They stay like that for about a minute while laughing together. Kanbaru thinks to herself "Oh wow. She's really cute. I probably should have kissed her."
