Fate / Stay Night: Unlimited Blade Works season 1

So Noshi and me have finally started the whole Fate / Stay franchise, though it might not be chronologically on how we watch them...

Because Netflix has only a few entries of the series so far, and we started with this one.

The Holy Grail War is a battle royale among seven magi who serve as Masters. Masters, through the use of the command seals they are given when they enter the war, command Heroic Spirits known as Servants to fight for them in battle. In the Fifth Holy Grail War, Rin Toosaka is among the magi entering the competition. With her Servant, Archer, she hopes to obtain the ultimate prize—the Holy Grail, a magical artifact capable of granting its wielder any wish.

One of Rin's classmates, Emiya Shirou, accidentally enters the competition and ends up commanding a Servant of his own known as Saber. As they find themselves facing mutual enemies, Rin and Shirou decide to form a temporary alliance as they challenge their opponents in the Holy Grail War. 

It's a lovely series, and I really like the Archer character and his strange looking motives, even though I have a theory... let's see in season 2 if it is the correct one then!

But I guess he is there to protect Saber, Emiya's servant...
