Here's the translation my gf did of the one second appearance of Kazuya in the Tonegawa spin-off: Excuse me sir, I need to speak with you.. Huh? It's your private jet.. Your son Kazuya is taking one of his classmates on it now He's using it to go to Maldives A classmate? Yes, this is truly embarrassing I apologize Is that so? It's that sort of friend .. Apparently, Tonegawa has to deliver this sort of news often and Hyoudou is disappointed that Kazuya is doing this/being used by his friend (the word used there means more associate than friend really)
