Yuu was that vampire's servant/sponsor/adoptee in his past life.

If they go back to being humans, they'll lose their gained powers. I don't think the author will change them back.

...I don't think he was normal even before. Who wakes up to massacre an entire troupe 'for the greater good'?? And blatantly lies to the rest of the troupes that Yuu's group is the 'traitor'?
Frankly, I wouldn't see that 'change' if the new monster settles inside him.

They are all mad. Which makes sense in a broken supernatural world.

Yeah, it doesn't make sense for Mika to be so weak. He got turned by the queen so he should be at least 10th rank or 9. Second, he got experimented too. Either he's a failed experiment or he's a late bloomer.

Partner? H*l yeah. I was worried there for a bit that it might be the girl team leader being referred to.

I feel pitiful for the loyal pet girl. Seeing the type of guy she has a crush on, and the devotion she has for him, sadly kinda hits home.

So much has happened in one chapter.

Ferid is too eccentric.

Why isn't Mika powerful then? He couldn't even defeat the 10th progenitor on his own.

If Yoichi's weapon demon would have been shown in the anime, fans would have gone feral for this dude.

I thought he had noticed him in the anime...

*Sign* I feel sorry for the kids being toyed like this.

This guy has been with Mikael for a couple of years and never brought up that he has his family's head till now of all times?

Friendship this, friendship that...too much.
It feels so forceful and manipulative.
