Heroes Aren't The Only Ones Who Can Get Stronger

SynopsisHave you ever played a game, read a book, watched a movie or anime, or anything at all similar to that where you see a monster or beast stay still and wait for you in the same location, never getting stronger or improving but simply letting you grind it for materials, rewards or experience?So you have thought about that, huh?Well have you ever thought how the monster or beast felt about being abused in such a manner? Being killed over and over again, so the 'Hero' can get the materials it needs to make a shiny new sword, some epic light or medium armour.Well guess what? Come on, guess. You don't want to guess... fine then, let me tell you.Those monsters and beasts feel eternal and infinite anger. They are created, spawned so that asshole can come kill him, then go and break into someone elses house afterwards and break their pots and pilfer their houses, all because they are heroes.But no more.For this little monster has gotten sick of such a life and has decided to break the chains placed on him. He will no longer wait for the heroes to kill him while he guards the lands of the Demon Lord for the Demon Lord to simply kill the heroes and then wait for the entire process to rinse and repeat.He will fight against fate and claim his freedom. He will rise above all monsters and beasts to become the strongest... or at least go from being a shitty minion to a late-game boss.
