Owari no Seraph Opening Impression

So the opening is by far one of the best ones I've ever seen. The song was well chosen and it was not too boring. It was very action packed and not cheesy...

There were a few things that I interpreted from the opening...

First of all the first few seconds show an older Mika, which means that he did not die (which I assumed from the first episode). It also shows a few shots of Lord Ferid (I think that's his name?) so I'm assuming that Yu did not kill him. I have a reasoning for why he isn't dead but I'll put that later. 

It was also shown that someone opened their mouth and there were fangs. It was not shown who it was but you could see blonde bangs. So we can assume that Mika has become a vampire. We can also assume this due to his clothing change and how it's nicer (I mean there's a gold chain and a golden emblem??). 

I don't think Mika became a vampire out of his free will, more like he was forced to become one...I'm honestly really excited because I want to see a battle between Mika and Yu. 

-REASON WHY LORD FERID ISNT DEAD-

So after watching episode 2 I have made a reason (which may not be right) to why Lord Ferid isn't dead. 

So at the end of the 2nd episode Yu stabs the vampire with his sword. But he is unable to kill it. Guren then comes in and kills her. He tells Yu that he couldn't kill her because there was no spell on his sword. 

In the first episode Lord Ferid was shot in the head. However, the opening suggests that he's not dead. I'm guessing that he's not dead because Yu shot him with a gun that had no anti-vampire spell.
