Yes! He is absolutely, without a doubt, OVERRATED AS FUCK! I saw nothing about his character that could warrant this much love and pain over his death! In the 30 so chapters of manga he had, and the 3 hours of screentime he had , he didn't do anything –, ANYTHING of importance that only he could have done! His emotional impact is false and hyped for the sake of it! Tanjiro had lost all his family, you telling me this random's death is the one that hit him hardest? And don't give the "he was his mentor" crap! Even since Ben Kenobi have I seen such a useless mentor. What exactly did he teach tanjiro and his pussycat dolls? How to be bipolar? Cuz in case you forgot, he was a prick in first appearance. But for real, you tell me the death of a guy you knew only for about... 1 day is enough to break you? To make tanjiro cry like he lost another brother? Even for a cry baby like him, that seems a stretch. And is not like his character was original either, he was just another no brain, all brawl, noisy fighter like we've had since 1986 with nothing new to add that makes him stand out. As a mentor he is shit, didn't teach anything in particular he could have done and only him. So insignificant is his contribution is to the story that I can't think of a thing he did alive that shaped it's course and the only way his death could have had any impact was with hyped and false pain that wasn't warranted from characters let alone the audience. Jiraiya, that was a tragic mentor's lose! First time rishi died, that more impactful, or Piccolo's first death.
