[Crossover] Tsujaya Doesn't Want to Inherit the Family Business

You are a lazy fish. But you are strong. So, because of your incredible fighting ability, all sorts of organizations come calling with offers: "Join the Rats in the House of the Dead. Let's change this twisted world and set things right..." "Join the Twelve Kizuki. You have what it takes to become one of us!" "Young man, I can see you have extraordinary bones. Join the Demon Slayer Corps!" Morikawa Tsuji Aya: "..." Morikawa Tsuji Aya (a polite but awkward smile): "Thanks, but no. I'm not interested." #I am the brother-obsessed one you can never have. # Ice-cold to everyone, but showering her little brother with praise whenever he appears. "I'm telling you, my little brother is the cutest, most precious treasure in the whole world!" "And my little brother is the cutest of all! He's a little brother you'll never get. Why are you looking at me? Being jealous won't help! He's mine and mine alone!" The organizations: Heh... who wants your precious little brother?! #We only want you. Your little brother can go somewhere else. # The organizations keep trying to recruit you, while paying no attention to your adorable little brother. Until one day. Everyone watches in silence as the "frail" little brother flies through the sky and underground, blows up the Demon headquarters, and demolishes the Port Building: "...???" Little punctuation mark, do you have a lot of friends? Everyone: "...Heh, so this is your 'soft and cuddly' little brother who needs to be pampered?!" Wu Yu, who has just blown up the Demon headquarters and is about to demolish Yokohama's port, slowly types a question mark: "...?" When did I get a brother? #A brother out of thin air. # Morikawa Tsuji Aya (tears streaming as she reaches out): "No! How could you forget me, my dear little brother! I'm your reliable big sister!" Wu Yu (a polite but awkward smile): "Thanks, but I don't have a sister. Goodbye." Morikawa Tsuji Aya: Tears burst forth.jpg Theme: Diligence at work.
