One of my favorite characters is Tanjiro Kamado from Demon Slayer. He's such a sweet, caring older brother to Nezuko and he's determined to save her from Muzan's curse. I love his kind nature and how even he gets annoyed at Zenitsu's antics (I still love Zenitsu though lol).
I love his growth in the series and the friends he makes along the way. He endured so much and when fighting demons, he shows no resentment, but sorrow when they're defeated. Muzan is another story though. XP
