Kidnap a Haikyuu!! Boy and Make Him My Brother-in-Law!

[A big crossover between the tennis and volleyball clubs, also known as “I Thought You Were My Friend, But You Want to Be My Brother-in-Law?!”] Atobe Kaguya [Kōtarō Bokuto]: Kaguya, a rich and haughty young lady, has no worries in life, until the puppy she’s been keeping since childhood runs off with someone else. Furious, she decides to raise the rarest creature in the universe. An owl that loves volleyball and goes “Hey! Hey! Hey!” sounds perfect. The girl holds out a no-limit black card: “Take it. I’ll cover your food, housing, and social insurance. Starting today, you’re my very own personal owl!” Kirihara Aiyo [Kozume Kenma]: Her idiot gamer brother’s online friend turns out to be a blonde beauty, and they’ve arranged to meet in person. But he’s too shy and afraid of being catfished to go alone. What a loser. As the best little sister in the world, she naturally has to vet the guy for her brother. When she sees that glorious face, Aiyo honestly says that even hesitating for a second would be an insult to her own taste, and immediately pulls out her phone to message her brother: “Catfish. Retreat. Delete him now!” I’ll take this gorgeous beauty off your hands for you. Sanada Aoi [Tōru Oikawa]: What do I do if this petite body that wants a boyfriend can’t survive one punch from my brother? Every day, I’m either hopelessly single or bouncing between becoming a beautiful widow. Niou Yusui and Niou Yuzuki [the Miya twins]: Everyone on the tennis team knows that Niou Masaharu’s twin younger sisters started dating at the same time. Yusui and Yuzuki agree to introduce their boyfriends to their brother together. They keep it secret from each other to make it a surprise. Then, on the day of the introductions, they stare at two photos that differ only in hair color, and all three of them freeze in place: “Your boyfriend and my boyfriend… are they the same guy?!” Akutsu Kuriko [Nishinoya Yū or Hinata Shōyō]: Fed up with her brother Akutsu Jin bullying her over her height and tired of her delinquent lifestyle, she decides to find a cute boyfriend to protect her: “Great, now he’s getting bullied by my brother too.” Echizen Nanasē [Kageyama or Hinata]: “After having a brother who likes me but loves tennis even more, I’ve got a boyfriend who likes me but loves volleyball most of all!” Thanks. I’m so lucky to have you both… Theme: I’m definitely going to fall in love!
