This song is the first time I have the idea that seiyuu are monsters. Don't think that you can sing a song by dubbing anime characters. The skills and breathing required by the song mobilize the whole body, which is difficult to some extent. In this song, seiyuu not only has superb singing skills, but also exerts the charm of the voice itself to the extreme.
There is also a song from the theme song "Xia Guang" of Guo Man's "Elf Century". I read this cartoon when I was very young. It tells the story of a group of penholders who defeated the Great Devil through difficulties and obstacles. The theme song "Xia Guang" is ethereal and graceful, without so many noisy elements as other anime songs.
There is also an unfinished song from the animation "Fox Demon Little Matchmaker", which appears in the second chapter of "Fox Demon Little Matchmaker". Wang Quanfu met Qing Tong in his previous life. Wang Quanfu broke through the resistance with Qing Tong and left the royal family. Then Wang Quanfu said, "Wanshui Qian Shan, would you like to watch it with me?" This sentence, the voice just fell, and the moment "Dream Back" sounded, people could not help but cry. It is clearly about love, but it is so magnificent.
