Sekiro is such a great game, the GOTY awards are well deserved.
I’ve tried my best to summarize the story as best as I can in 5 minutes. There is still so much I couldn’t include without breaking the compactness of the video. This is as spoilerful, as you can possibly get in 5 minutes.
I have finished it multiple times, I have seen most of the possible endings, some are highly different from others, choices do matter a lot. This one is called immortal severance (for obvious reasons), and this is the one I had on my first playthrough. Might be the most common one.
At the end of the video, Lord Kuro says “I wish there was another way“. There may be. :)
