Plot twist they're the original generation of soukoku
The concept of Natsume being younger than Fyodor just doesn't make sense to me.
Natsume just feels like someone who's existed for centuries, watching from the shadows.
If anyone is going to have been around for as long as Fyodor other than Bram, I'd say it should be Natsume.
I can't fathom the idea of him being some regular middle aged guy.
They are literally the cat and the rat.
