Yesterday i found "Eden of Witches" so far i like it even thought it seems that it is kinda going too fast.
Basically the world is kinda like "The Dark Sun" (D&D) where world is dying and plant life is becoming rarer and rarer and only people that can find and cultive that are witches and as expected they are being killed and hunted for well hoarding all that shit (its not as dark as Dark Sun but that is the 1st thing that came to my mind when i was reading it) and it follow the story of a girl and her familiar trying to get to Eden.

"In a world devastated by humankind and forsaken by plants and animals, only witches have the power to communicate with nature.
A long time ago, plants and animals lived in harmony . . . until humankind came to power and, unable to coexist with nature, destroyed and exploited both flora and fauna without a second thought. Now the world has become a barren wasteland. But witches have the power to speak to nature. Blamed for the extinction of plant life, and feared by humanity for their powers, they hide away from the rest of humanity in secret lairs bursting with greenery.
Pili, a young witch-apprentice, has set out on the roads accompanied by the wolf Oak. However, she is not accustomed to the world outside and traveling long distances. Her fatigue quickly takes its toll, and she ends up injuring herself by tumbling down a rocky slope! Fortunately, a boy named Bowei finds Pili and takes her home to nurse her back to health.
However, the arrival of the unfamiliar young lady arouses suspicion among other villagers, who quickly discern her true nature as a witch. And all captured witches share the fate of execution!
Eden of Witches is a magical and lushly illustrated coming-of-age story perfect for fans of Princess Mononoke, Nausicaä, and Witch Hat Atelier, brought expertly to life by rising star manga artist Yumeji. It will sweep readers away into a fairy tale where witches and their familiars are the last keepers of the natural world."
