The first one: Uchihiro Shoko Asahara Uchihiro Shoko Asahara is the second person besides Ootutuki Hagoromo who can manipulate Kyubi no Youko and fight with its strength. Kyubi no Youko followed him and competed with King Senju Hashirama in Terminal Valley. Unfortunately, he met Uzumaki Mito and became the exclusive bijuu of Konoha Village.
Second: Kyubi no Youko and Namikaze Minato are always complacent, and he is very dismissive of other ninjas. When masked men opened Uzumaki Kushina's seal and released Kyubi no Youko, Kyubi no Youko hurt Ninja Village angrily. As the fourth generation of Naruto, Namikaze Minato not only defeated Masked Man, but also divided Kyubi no Youko into two parts, sealed in Naruto and his own body. Kyubi no Youko mentioned this in his conversation with Naruto, and he was very interested in Feng Boshui.
Third: Naruto was a crane tail in his early days. Although Kyubi no Youko was sealed in the body, he couldn't use Kyubi no Youko's power, and Kyubi no Youko unexpectedly had Naruto's consciousness, looking forward to "returning to the Jianghu". In the middle and late period, Naruto used his mouth to avoid influencing Kyubi no Youko and became the ultimate power. Today, Naruto is Kyubi no Youko's friend and family. How can he disrespect people?
Fourth: Uzumaki Mito Uzumaki Mito is the first pillar of Kyubi no Youko. At the end of World War I and World War II, Mito married the first generation of Huo Ying and ensured the success of Kyubi no Youko. Mito became a pillar force until the death of the deceased, and Kyubi no Youko never stepped on it rudely. This is not only the power of the first generation of Huo Ying, but also the seal power of the vortex clan to a great extent. In other words, Kyubi no Youko can't indulge in the days with beautiful pictures. To Kyubi no Youko, Mito is a respectable person. At least Mito's seal power can make Kyubi no Youko cry and make him behave.
Fifth, Ootutuki Hagoromo Ootutuki Hagoromo, who founded the enduring sect and started the ninja era, separated ten tails and turned them into nine bijuu, and taught them carefully. Kyubi no Youko was just born at that time, and Ootutuki Hagoromo taught them to recognize Ootutuki Hagoromo as their father, so Kyubi no Youko respected him very much. That's my answer.
