What's one thousand minus seven?
But I'm getting ahead of myself. This brilliant Japanese-language rock song explores the descent into madness, and is known for being the opening theme of the animated series Tokyo Ghoul.
Turn on the subtitles, but it's kind of optional here. It's nice to know what he's saying, but his voice really tells the story.
I would recommend the first season of Tokyo Ghoul to anyone with a strong stomach (as it's about cannibalism and makes most Western shows look like Saturday morning shows for kids), but after that, it got weird. The book series wasn't done, so the anime wrote its own ending. Years later, the book series finished, the author wrote another book series which comes after, and they adapted that into two seasons, but rushed it (they had enough content for at least three or four seasons). Imagine you really want to watch the newest Marvel movie, but you literally haven't seen any others. So you find a YouTube video that sums them ALL up in five minutes. That's what Tokyo Ghoul :re was like. As a book reader, my wife was annoyed. As an anime-only watcher, my wife had to explain everything to me.
The first season is the only one worth watching, though the music was consistently good throughout. Also, TK comes back in the last season with his song Katharsis which was also, similarly, about madness.
But the first season's opening was a work of art beyond just the music. The colours. The flowers (or whatever they were). The reflections showing the person's true form.

Then they did an acoustic version for the second season. There is an official acoustic recording, but I prefer the one from THE FIRST TAKE. TFT is a YouTube channel that works primarily with Japanese artists, but they have worked with western artists as well (I've seen Avril Lavigne up there, and she's Canadian). Basically they film a singer or band perform a song in a single take, no do-overs. You also get to see the performers up close playing the music.

So there's a few versions. The full version/official video, the short anime version, and the acoustic version.
As for the anime... I said it's about cannibalism, but that doesn't quite do it justice... or explain it. It's about a nerdy guy who notices a pretty girl at the café, and she asks him out. As they're walking, she sprouts four parasitic tentacles from her lower back called kagune which function like claws. She's a ghoul, a supernatural humanoid entity with rules similar to a zombie in that they can only survive on human flesh (and, for some reason, coffee). Defending himself, a freak accident disfigures both of them. While trying to save them, the doctors are only able to save him, but he inherits the power of the ghoul, and finds himself unable to eat real food. He's taken in by a ghoul community and seeks to hold onto his humanity, while he's hunted by other ghouls who want to consume him, partly because he's only half ghoul, and partly because of who "made" him. This anime pulls no punches. They made a movie version of it — three, in fact, to cover the full story the first season covers — and at least the first one was rated NC-17 in the US for violence alone. Tokyo Ghoul may be animated, but it is not for kids. Here's a trailer for it — in English, no less (most anime trailers, even those translated to English, are in Japanese): https://www.youtube.com/watch?v=vGuQeQsoRgU
