Summary
Spamton thought it was the end of the world when he saw a beacon of light pierce through the summit of Mount Ebott and soar into the sky, not knowing that he had born witness to the shattering of the ancient barrier that trapped monsterkind beneath the mountain.
Magic had begun to flow back into the world, and creatures he had believed only existed in fairy-tales suddenly began to settle down and live in Elysium city.
At first, he thought he could ignore it, but after his workplace adopts a monster integration program, and he is forced to look after his new coworker, he finds that his life is suddenly full of questions from an obnoxiously curious ant.

Summary
He swallowed hard, trembling but unable to tear his gaze away from the being before him. Fear still rooted him in place, but curiosity—foolish, human curiosity—kept his eyes fixed on the way the moonlight caught the monster’s fur, the faint curl of his antennae, the glint of sharp teeth in the dark.
It should have been pure terror. And yet… it wasn’t.
And that fact almost scared him more than the monster did.
