Just think of it as a friendly warning. That's just the kind of place that this is.

[ ... Almost as friendly as "memento mori": Remember that you, too, could be turned into something distinctly not-human at any turn because reality doesn't really follow any rules around these parts. Mayuzumi can probably see the vague smirk that Akashi wears for a moment or two without even having to actually look at Akashi. He can't wait to see what kind of creature that fate decides to twist him into someday; Akashi feels like Mayuzumi can't escape it forever. Maybe part cat, Mayuzumi seems to have feelings about so-called "catgirls".

And then, abruptly, Akashi decides to change the topic to something that's probably not entirely comfortable given that his mouth is very, very close to the back of Mayuzumi's neck at the moment. ]

I think I've also become somewhat venomous — I haven't checked to be sure, but I do have fangs right now.

[ Another friendly warning... ]
