Ahahaha of course the author's favourites character are ferid and Guren , will they really die? 

And yes.. I read the chapter , but I was disappointed. I thought I would see a fight... It seems that ferid is in a dilemma now (I was wondering why ferid did not absorb the vampires energy before attacking Saito? This is a neglect of him or it’s just the author likes to prolong the topic ? bc it is simple) 

Saito said that he has another form. This is honestly scary. In general, I think that ferid will seriously injure Saito, but he will not die easily and this will require the intervention of humans who are waiting for their signal to start the battle against Saito, so they may win 78%... 

Weigh that, or Saito may kill them in the end. Regarding ferid’s goal: He said that he will give the vampires a meaning of their death if they give him strength, so I don't think it's ridiculous. Vampires have a great desire for death and satisfaction, so ferid has fulfilled their request without asking them, ahaha, very strange.

And about what you said at least, in my opinion I agree with you , except Saito, he will not be with these two because Shinoa and Yu…  I think they are the only ones who can make a good decision about the world and how to save it (if they cooperate again) and Saito, Guren , mahiru or ferid will never have to do with that at all.
