My favorite anime character is Kei Kurono from the anime Gantz :)
He is my favorite anime character because he made me feel like someone like me could be worthy of a hero and the main character. Usually people like Kei are side characters who die. A lot of gantz is from the pov of kei in his mind voice so you get his true thoughts, he's a pervert. He's selfish, and he's a coward, he's unabashedly human. But out of his cowardice, due to his fight or flight reactions he survives. He outlives his friend Kato who you'd think is the main character or hero because he's so pure and selfless, and that's what brings kato's demise. I did both your contest posts with same answer because i'm not sure its for same contest or not :)
