But then He realizes that one of His angels had given Him the wrong name
of the victim (Kun-chan isn't under His responsibility anymore, so He doesn't
watch her) and returns Stargazer to life with profuse thanks for his service
to mankind. :P

...and then the Devil goes and takes Stargazer back because he was so good
at buggering off from Hell the first time that Satan wanted another round!

buggering?...
Anyway:
But then Kun-chan, without meaning to, provides a distraction for Stargazer.
While she and the devil are, err busy, things get even hotter and more
steamy, causing a pressure build-up that bursts a temporary opening that
allows Stargazer to 'port out, with the opening sealing behind him. 

Pity Kun-chan is dead and not in Hell and the Devil is busy with Stargazer
up against the wall, so the above doesn't happen.
