>>8468034In a fight, Mori can handle herself. Even if she got her ass handed to her, there's nothing we've heard which can kill a Shinigami. So time and stamina are on her side. It's how she always gets the Phoenix, even though Kiara is a more experienced warrior.
The ability to portal to another area could likely bring Mori to other planets but she never really had use for it since her job is to take care of humans. Kiara is the exception to that and their history obviously goes far back.
As far as reaping actual souls goes, I think she can either be there at the time of death and quickly collect them but maybe there's also a window where the soul remains in the vessel and isn't harmed. So she (or another Reaper) can get there and do what needs to be done.
