Inside the novel "Inmarok", the world is an endless battlefield between angels and demons.

In an era where the world's balance teeters on the edge, Yohan is reincarnated as a half-human, half-demon born to a mortal. Sometimes suppressing his surging demonic instincts, and sometimes weaponizing them, he must manipulate the characters of the novel to punish the wicked. Just like a true demon.

A demon's whisper is traditionally a signpost leading to ruin. If you lend an ear to their words, you will suddenly find yourself walking straight off a cliff.

However, Yohan's whispers are the only exception.
