Tian Dao Zhenyu transmigrated into the world of Demon Slayer by accident. The moment he opened his eyes, he found himself a low-ranking demon on Mount Fujikasane. His bloodthirsty instincts made his whole body twitch uncontrollably. Watching living creatures walk right before his eyes, he nearly lost control and pounced on them.
Damn it, if I can't hold back, then I won't! If I'm going to kill, I'll show you how it's done.
Just as a member of the Demon Slayer Corps was about to be killed by a demon, Zhenyu finally made up his mind. He charged forward and bit through the demon's throat. As the other's blood poured into him, he felt his body changing, and decided on the path he would follow from then on... using demons to kill demons, fighting darkness with darkness.
