Any predictions about what the MC is? There's been a host of very very old vampires warning him to not get bit by any vampire (well, Suzu is an exception due to their union) that doesn't have red eyes, though those same vamps aren't exactly willing to say "WHY" he needs to wait.
Personally, I'm thinking...... [redacted due to changed mind and more thought on the subject].
Okay, when I originally typed this, I thought "male vampire", but then started thinking more about the other characters he interacts with, and the whole 'god' aspect of things...
What do you want to bet he becomes something akin to a Chimera? In that he has powers and abilities from every...single...myth type character? So, a male vampire, werewolf abilities, Siren abilities, cat abilities... etc?
It will be interesting to see if the author takes that route with things, further expanding on his godlike powers, and let's face it... Seeking someone like Aki (or Lilith, though we've never seen her in person), react to a Male vampire, which they claim simply can't exist? Would be fucking hilarious.
Granted, Aki would likely jump your bones the first chance she got... but I digress.
And yes, I do love the dark aspect of Aki's story, and how she's written. She actually rather accurately recreates the behavior of someone who went through the kind of treatment her story tells.
