Then, between one rice bowl and the next, your otouto grows 15 centimeters. You are no longer the dekai one. The new version of your brother has overwritten your physical identity.
You open your laptop after a weekend away and see a 5GB system update.

Let’s linger on dekain. In standard Japanese, you’d say dekai (大きい – casual) or dekakatta (でかかった – was huge). Dekain doesn’t exist in textbooks.
However, in casual speech, young people sometimes attach the explanatory -n (ん) to adjectives to add a tone of realization or mild surprise. Example: “Ame, yamunda” (雨、やむんた – “Oh, the rain stopped.”)
But dekain goes further—it nominalizes the adjective. It turns “huge” into a thing: the hugeness itself. So when the sister says “maji de dekain,” she’s saying “Seriously, [this situation of] hugeness,” leaving the listener hanging.
That dangling feeling is the joke. And then she adds “new” —an English word that grammatically modifies nothing. Is the hugeness new? Is the brother new? Is “new” his name?
