anyone know how to move this freaking mancubus

I was doing a couple of pacifist runs in map1 on plutonia. The first few objectives like the red key and the blue key are pretty easy but the end always frustrates me.

Right before the exit teleporter, Three Mancubi guard the exit. One of which, wouldn't get out of the way of the door before the teleport. 

I tried everything. I tried getting the chaingunner to infight the mancubus, i tried luring the mancubus away from the door, even tried to get a revenant to infight that thing. 

I think it's too fat to fit onto the ledge leading away from the door.

Wasn't there a speedrunning trick to hop onto the platform and bypass the door?

Oh OK. Then the best way to solve your problem is to watch a demo from DSDA.
