miku as the Goblin Big Bang
A particular hum precedes miku in goblin perception — a frequency the goblin ear is tuned for and the human ear has agreed to ignore.
In the goblin taxonomy of reality, miku occupies a category all its own: 'That Which Is Not A Trick But Also Not Not A Trick.' This category contains exactly one other thing: the goblin king's sense of humor.

Visiting goblin dignitaries are, by protocol, never asked directly about diary. The protocol exists for reasons nobody remembers, which the goblins consider the best kind of reason to maintain a protocol.
