Harvest March

From [MangaHelpers](https://www.mangaupdates.com/groups.html?id=1011): In a small village by a forbidden forest, the siblings Noie and Kubante live together peacefully. Noie is more of a mother than an older sister to Kubante, and she is loved by the village for her industriousness and bright personality. She loves Kubante very dearly, but he's little and weak. He's unable to do as much work as many of the other boys, and he is mocked for it by the villagers. One day, an older boy named Shido invites him and some other children to come into the forest, with the promise that they will be changed. The change is much more brutal than any of the children could have foreseen. The powerful monster that Kubante becomes in the depths of that forest is no longer human, though he remembers his love for his sister. The other children lose their humanity completely, and use their deadly new power in an attempt to murder all humans for the monstrous 'mother' that gave them rebirth. Kubante's loyalty will always be to his beloved sister, so he must stand against the others who want to see her, and all humans, dead. [tethysdust]
