Alot of people noticed a con to Dazai's one bandaged eye.

It wasn't wounded, no, he just kept it hidden so it would be better in the dark.

There is a reason you have two eyes though...

He often ignored or suppressed this problem, but it was still obvious.

He often tripped on the tiniest things, couldn't tell where things really were and walked into doors.

Like he was drunk, constantly.

But no one mentioned it, they did all in fact like the way their head was attached to their body with no problems.

He walks down a hall, with you at his side, as always, before trying to go to his office and... bang.

"Ah— Hmph.... Who put that there?"

And he plays it off, as usual.
