Overall I would say two characters: 1. Rengoku 2. Tanjiro I choose Rengoku because he is basically a legend and an amazing person whose death shall not be in vain when Infinity Castle comes out! I also choose Tanjiro because he never gives up no matter how injured he is. He's selfless, putting others needs before his own and he always tries his best to keep that happy smile and those kindness and fiercely warm eyes of his. He kinda reminds me of Izuku Midoriya from MHA but like in a whole different dimension.
