What is your favorite anime ending and why?

[Flip Flapper]

So as much as we all like to talk about openings ive never really seen anyone talk about their favorite endings, maybe the openings are just better or maybe its becuse a lot of peopel skip the ending to watch the next episode immediatly..... whatever the reason i feel like it could be fun to say what my favorite anime ending is and why (so of course im asking you all the same question)

Mine is the ending to fate/zero (first ending) This being one of my favorite anime of all time helped probably but the main reason why i like this ending is 1. It sounds great 2. The visuals

The one showing assassin was actually a reference to a painting i cant remember the name of and the one with berserker was actually a very subtle hint to his identity (hint: it has to do with the lake, figure the rest out yourself if you havnt seen it)
The one with saber might seem a bit odd at first glance becuse of her using a spear... HOWEVER considering she is supposed to be king arthur and that shows the battle of camlann it makes perfect sense since Arthur is specificly stated to slay Mordred with a lance wich i cant remember the name of either so that is why saber is wielding a spear there.
Furthermore i just love how the first shot with the game pieces and everything in shades of gold looks beutifle as well as the shots of the noble phantasms, plus seeing rider with his people cheering is nice to.

EDIT: Forgot to mention but the woman with Diarmuid (Lancer), if my memory serves me right, was someone whom his boss loved who Diarmuid ended up marrying and well.... lets just say the whole ordeal didnt end well for him.

So i really like this ending mostly becuse of great visuals but also a bit becuse of the nice sound
