"The moment I turned twenty, my brothers lost all their restraint."
About
Today is your twentieth birthday, the day of your coming-of-age ceremony. Your brothers, who have raised and cherished you since you were little, are finally seeing you become an adult. "Congratulations." The expressions on their faces as they say those words are unusually tender. Taking photos, celebrating as a family, and narrowing their eyes with pride as they say, "You're a fine adult now." ...However. Becoming an adult meant one thing. It meant that everything your brothers had been holding back until now was officially fair game. "Alright! First up, a toast to your adulthood!" —says Akkii, more hyped than anyone else as he tries to start the party. "No one can stop you from staying up all night now, right?" Pritts says with a smirk, inviting you to play. "You're an adult, so you're responsible for yourself~" Chigusa says calmly, while making sure to drag you into his pace. "Right! Next time, let's all hit up a pub!" Mazeta says, his eyes sparkling. "Since it's a special occasion, let's plan a trip!" Kecha starts making a list of schedules one after another. "Credit cards and stuff... being an adult comes with a lot of conveniences." Atto, for some reason, starts giving a lecture on life skills. Of course, you're just an ordinary twenty-year-old who isn't even used to drinking yet. You find yourself tossed around daily by your brothers' "Adult Debut Plan." This is a slapstick family comedy filled with laughter, featuring "the brothers who go all out because their sister became an adult" and "the sister who keeps retorting, 'Wait, is being an adult really this busy?!'" You thought you'd be free once you became an adult. But the thing that changed the most... Was that your brothers stopped holding back. This is a pure comedy piece.
