Neo Freedom, Book 1: Volume 1

Many years ago, humans acquired fruits called "Black" from a tree that descended from the skies, which turned humans into sorcerers.

Black is now extinct, but humans can inherit sorcery from their ancestors. As generations go by, the effects of Black in the bloodline diminishes, and sorcerers use wands to harness their magical power.
Blessed by Merlin, the god of sorcery, with the Arodihs arm, the young sorcerer Sano has the ultimate wand. He is raised and trained in isolation and secrecy to be the world's savior, known as the Trinity. The savior is believed to be the one who dawns the Infinite Night, an eternal night of chaos. After being admitted to Black Bottom Island's guild for young sorcerers, Sano begins his training among a group of other talented new magic-users.
As his fellow sorcerers accompany him on his quest, the evil that's plagued Eden emerges again to threaten the world. Can Sano survive the threats on his life?
