"What exactly am I? A human? Or a monster?"
This was the powerful demon slayer named Niyaji's current dilemma. He had never imagined that, as a human who expelled Demon Beasts, he would one day turn into the very monster he most loathed.
When he first discovered that he had become a monster, the dignity of being human and the glory of being an Exorcist had led him to choose suicide immediately, preserving the last of the dignity of Niyaji the demon slayer.
However, he discovered an extremely despairing matter: with his current means, he simply couldn't carry out this act of suicide. His vitality, or rather, his state of life, had completely departed from the realm that a human could possess.
"Niyaji, are you thinking about how to kill yourself again? What's the matter? A great Exorcist consumed all day by such a mundane issue of life form!"
