Great Sage in Black

In the magical kingdom dominated by the Holy Light Church, Cross, who possesses dark magic, obtained the Black Lord of the Rings after undergoing dark rituals, met the Dark Magister Valentine, and entered a magic school to study magic. In the magical world of magic, dark magic has always been hidden in the dark. Cross originally planned to learn dark magic in secret until he became a magician, but when walking in the darkness, things in the darkness would inevitably peek. Cross was attacked from the darkness in his first year... Light has its reason for existence, and so does darkness. There is no right or wrong in power, and talent is the source of right and wrong.
