I have been reading a webnovel called supreme magus my version takes place in the future where lith learns to enjoy life takes our young hero (you choose name) who was orphaned and reincarnated from another world just like lith however because of the hatred he has the only element is the dark element a few of his move set are
hatred blast a blast entirely made of dark
magic
shadow warp allows him to turn into a shadow that can teleport
dark cacoon when having a severe panic attack darkness energy surrounds (you choose name) protecting him from the world making any one who dares enter loose life energy
death vision unlike lith's death vision (you choose name) can see places were living beings died and use it to power his skeleton
