Konomi ja Nai kedo: Mukatsuku Ane to Aishou Batsugun Ecchi

Running a household on bickering is Ryouta and his older sister Rina's specialty — constant, petty, exhausting arguments that neither of them seems willing to drop, and they can barely stand each other. Pretty standard sibling stuff, until it isn't. Somewhere underneath all that friction, something else has been building, and when they finally acknowledge it, their whole dynamic shifts in ways neither of them expected. That tension between hating someone and being drawn to them is where this 2-episode OVA from New Generation lives, and it leans into that uncomfortable push-pull with a mix of comedy and genuine dramatic weight. The character work is grounded enough that the conflict feels real rather than just a premise to get through. If you've watched Kiss x Sis or Yosuga no Sora and you're looking for something in that same space, this covers similar territory with a focus on the slow unraveling of a relationship that was supposed to be simple. It's adapted from a manga, so the characters come in with some established history and personality rather than feeling like blank slates. At two episodes, it doesn't overstay its welcome. It's a short, character-driven piece that earns its moments through the dynamic between Ryouta and Rina rather than just the setup alone. If the incest genre is something you already engage with, this is a solid entry that takes the sibling rivalry angle seriously before moving forward.
