The author is lazy: Legend has it that three hundred years ago, the ancestors of the Miyamoto family offended the gods and were cursed by the gods, so that their descendants would show fox tails and ears whenever they got emotional. As for why they offended the gods, the ancestors who knew about it were all because the villagers saw the exposed tails or ears, so He was burned to death before he could even keep the notes. From then on, no one knew or asked why he was cursed. In contrast, the first family motto of the Miyamoto family became "Hide well and don't reveal it." So what will happen to the four Miyamoto brothers and sisters who carry such a curse?
