Here are some of the characters that I find very comforting. I figured I'd put this here because... why not?

• Serizawa Katsuya- Mob Psycho 100 (He is a pretty big comfort character for me because I relate to him a lot. I think hes great ;o;)
  
  look at this man
• Shou Suzuki- Mob Psycho 100
• Aikuro Mikisugi- Kill la Kill (He's a pretty big one too.)

(I have many more comfort characters but I can't think of them at the moment...)
