I said, didn't I? Most familiars have ethereal humanoid forms around their Cores. If Linfel wanted to pass by as a Familiar, he had to use his Magic Energy to create a similar thing. So, yes, he does have a face, a body, etc... It's just that it is very small, around 30cm more or less, like the other Familiars. That's how I picture it. Think about it as a small semi-transparent yellow body around his core. It will change color once he levels up.

Usually, you would have such questions indeed. And I did think about adding something related to it to the story. But in the end, it seemed like something too boring for the readers, so I simply let him speak normally and used the normal concept of time, etc...
