What's the ONE anime that truly stuck with you ?

[TraderFX]

just curious what’s the one anime that really stuck with you?
for me, it was Attack on Titan. The story, the music, the twists I still think about some of those moments

What about you?

There are so many anime that I love so much but it's going to be Demon Slayer that have stuck on me more than the rest I've watched over the years.
