What are some anime with exceptional endings that left you in AWE?

I recently finished my 2nd watch of Shingeki no Kyojin and I am still blown away by that ending! The world building, character development, themes, the beautiful animation and last but not least, the arc that Eren has gone through is nothing short of exceptional. <br><br>I honestly cried like a baby when I also finished **Attack on Titan**, **A Silent Voice** and **Your Lie in April**. These endings left me speechless, especially that of **Attack on Titan**.
