Ahhhh yay! That means I at least sorta know about Alvis! XD
I think detailed parts of all personalities will have some differences XD But as soon as I started thinking, I was like "I KNOW WHO HE REMINDS ME OF"
Yesss, he is a great character in a great anime. If you're not into sports anime, you may not be a fan, but it's hilarious and inspiring and emotional and the music is great too ahhhhhh
