It's not that their eyes are closed, they see in widescreen!
Heeey, i never thought of it that way. XD
They're all Asian, they can sense their surroundings, they don't need to see. It's the way of the NINJA!
And North Italy/Veneziano from Hetalia!
But, can they still see why kids love Cinnamon Toast Crunch?
FULL METAL ALCHEMIST
Yay! Finally got it!
Where is bottom middle from?
That's Lau from black butler.
Hmm. I've never seen that anime...
It's pretty good, funimation's youtube channel has all the episodes if you want to check it out :)
Because that's how their characters are designed and more often than not the main characters are designed to be more outlandish and noticeable than background characters to keep them memorable. Closed-eyes can be used to represent a knowledgeable character, or a sly character. Other times it's used to show that a character has poor vision and constantly squints to see, but that's rarer (surprisingly).
Also, considering Japan's still a country with humans, there are also small-eyed people as opposed to large-eyed people. I'm guessing closed-eyes are used to represent a character with "squintier" eyes.
Ichimaru Gin :D
Lol, "stereotypically Asian character." We love them. :3
Who does he voice?
I'm not positive about this, but I believe that is a anime stereotypes.
