You can use the trenchcoat to just bypass the Kur boss (though I am sure this is known). I haven't watched runs so I don't know how that fits in to the route. Interestingly you can't exit through the left though you can through the right.
There's a video. Hope its useful, its pretty obvious.
EDIT: I haven't beaten the game yet so I dunno if all bosses need to get killed or not. Just an observation.
