Wild Arms Flower Thieves

Thousands of years after a war between humans and demons turned the world into a scorched wasteland, humanity clings to survival in the overcrowded city of Upper Hose. Flowers and other flora are rare and valuable in this dystopian future. When a plant-eating monster known as a Flower-Thief attacks a mysterious girl named Jechika, a young boy named Maxi uses a forbidden ARM weapon to save her. As a result, he is expelled from the city for using illegal technology.

Forced to leave everything behind, Maxi sets off into the wilderness with Jechika and a florist named Gi. Together, they embark on a quest to restore the balance of nature throughout the world and make the earth habitable again.
