Into Extinction

80 years ago, a war ended in disaster that shook the world. Monsters from other worlds were brought in randomly, wrecking ecosystems and challenging humans for land. Now, humans have already lost control of the oceans, and what settlements that remained were patrolled by hunting guilds, maintaining the balance in territory. However, some hunters have their sights set on something big, to reclaim the lost land and sea. Risha and her sister Ziyan are hunters with such beliefs, will they succeed in driving the monsters into extinction, or will their actions spark a retaliation that'll drive humans into extinction?
