Welcome to the Vice community Jenkato94!
Nice AMV Taka! I came across that one too when I was surfing YouTube.
That quote is a good one, it's a tear-jerker as well.
Yeah I'm pretty sure. I've been following the series and according to Funimation's sub, his name is Keido. Also, on MyAnimeList, they put up his name before the second episode was released, and that was when his name was introduced. On AnimenNewsNetwork, it says Keido too. :)
