I hate how not getting enough sleep is seen as a sign of excellence. That's wrong. It's a sign of incompetence. He's too incompetent to delegate responsibility or find suitable underlings. By being the only one doing the work, the instant he's out of commission (death, sickness, or otherwise) the entire administration (and country) collapses. He isn't doing a good job. He's making a ticking time bomb on a national scale. If it wasn't for anime logic i'd think that the reason the documents take so long in the first place is because he doesn't get enough sleep to do them properly with a fully active mind.
At least our MC isn't in mortal peril for once, but we all know that won't last.
