Some of my favourites have already been mentioned - Nichijou is just unbelievably good, always - but there’s plenty more!
This is pretty much the sound of my childhood. I couldn’t imagine watching an episode of The Next Generation without listening to Patrick Stewart’s, ‘Space, the final frontier…’ at the start–it’s genuinely like sinking into a warm, soft blanket for me. I’ll always have a lot to thank TNG for - for all its problems, it played a huge role in teaching me what it was to be a good person as a kid, and I think I’ll always look up to Captain Picard in a way that I just can’t imagine doing with any other fictional character - and, every time I watch this intro, all those feelings just come flooding back.
Anyway, to move away from nostalgia for a second, here’s a relatively recent entry! A Place Further Than The Universe was my favourite anime of last year, and this intro does an amazing job of getting you ready for the show! It’s a story of adventure, of overcoming stagnation and the pressure to just fit in, and of finding true friendship–and the intro manages to express all of that. At the start of the show, it prepares you to go on a journey with these characters–and, by the last episode, you’ll be tearing up watching at, at the thought of having to say goodbye.
(Also, just as an aside: if there were ever to be a Star Trek anime, I can think of far, far worse things for it to be patterned after than A Place Further Than The Universe. I think they’re supposed to be making a couple of animated series right now, so… Hint hint, CBS?)
Next up is actually an outro, rather than an intro - so, uh, feel free to disqualify! - but still: I absolutely adored Yuru Camp’s ED, and never skipped it. It captures the vibe of the show perfectly, and the music that accompanies it might well be my favourite song from any anime last year. It’s pretty much what would happen if you extracted the essence of peace, relaxation and spending time with good friends, and poured it all into a one minute thirty second piece of animation.
I’m probably gonna come back and add more later, but that’s all for now!
