LH-11

For years humans lived sure with their reality and everyday lives.
Nobody was aware of the terrifying truth lying far beneath the ground.
The terrifying truth of loudhailers. Indeed, they were and had never been just inanimated things. 
They were living beings, so shy that they never showed themselves to humanity. From the moment they were discovered, so was their potentiality, and evil men exploited them for filthy money, selling them as mere objects.
Now, our hero, LH-11, had just broke free, and he had only one purpose. Tell the world, yell the world, about their slavery.
