This amazing video got official english subs. Support it here!!! - You can guess the content by the title, I suspect.
Subs are hard coded btw, sorry. Nothing I can do about it, but if someone wants to make a transcript themselves and use the available raw and make your own softsubs, have at it. Too much work for me.
