[Demon Slayer: Kimetsu No Yaiba] Don't Blame Me for Being Ruthless

I have the highest IQ, the strongest ability to act, and the deepest tricks, but I have come to a world of cannibalism - on the physical level. This story has to start with time traveling to another world. I, Toru Watanabe, a sixteen-year-old male high school student, had no choice but to silently pick up a knife in the chaos, and let the demons of Demon Slayer World look like they have seen me since then.
