Demon Slayer: I Can Customize My Abilities

"Who are you?" The veins on Kibutsuji Muzan's face popped out and he asked angrily. Even though the night had not faded, he could see the strange boy's pale skin, blood-red pupils, and two deadly and small fangs on his lips. This is an inhuman existence like himself, but he is not an evil ghost controlled by it. "You are the stepping stone for me to become a perfect creature, so feel very honored for this!" When everything finally settled, the boy dropped the ghost in his hands, which had turned into a mummy and gradually disintegrated into ashes. Looking at the dying members of the Demon Slayer Squad below and the vampire army crawling in the darkness, they turned their backs to the sun and laughed wildly. At the moment, he is bathed in the sun. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
