• "Hentai" is a type of anime or manga with pornographic content. The original Japanese term describes an abnormal sexual desire or act, as an abbreviation of hentai seiyoku ("sexual perversion"). "I chose it because it's a sensuality, or a sexuality as well," the "Con Altura" hitmaker explained to El Pais regarding the song title. "Many times for me it is much more interesting what is not explicit and the hentai, just for the fact of being drawn. I think it is very sensual and very beautiful."
• Rosalia delivers the verses of the sexually explicit song in Spanish, but sing/speaks the ecstatic chorus in English.
  
  So, so, so, so, so, so good
  Good, good, so, so, so good
  So, so, so good, so, so, so good
  So good, hmm
• Rosalia released "Hentai" as the fourth single from Motomami on March 16, 2022. "In this new album, there's some humor. In my other projects, I didn't allow a sense of humor," Rosalia told i-D Vice. "'Hentai' is much more suggestive, much more erotic for me. Hentai is more interesting than conventional porn. And why not talk about something like that as an inspiration for a song? Having sex is part of life. It's all the same. I put everything on the same level."
• Rosalia recorded the song with The Neptunes pair of Pharrell Williams and Chad Hugo in Miami. The other collaborators were David Rodríguez, Sir Dylan, Noah Goldstein, Michael Uzowuru, Larry Gold, and Jacob Sherman. "I'm doing this for fun. I love the way he makes beats," Rosalia told Billboard of working with Williams. "I love the way he writes."
• Rosalia wanted to explore the erotic superiority of female energy but was surprised that making an erotic song became a topic of conversation. This showed her the strictures still imposed on women.
  
  "I've realized that there's something that happens to many women – so many times, people reduce a woman and her talent by limiting her to a prefabricated category," Rosalia told The Guardian. "Pure cliché – the crazy one, the girl boss, the witch, the messy one, the histrionic, the diva. I hope I can dissipate all those useless categories, and take a little bit from each of them, play with all of them in my projects."
