Of course, this is just speculation.
Besides the theory that a believer killed the Saintess and escaped, there's another guess that no one was actually killed and that a Saintess escaped, with the temple unilaterally announcing the death to erase her identity.
As for the person being pursued to Satellite City, it's not difficult to screen them, it just takes some time.
Outer Zone players can't easily access government agencies to get passenger lists, so they use a more straightforward approach, which is publicly offering help to "oppressed" believers.
Outer Zone players can't say they're helping those who killed the Saintess, and believers aren't keen to trust their words, so they keep things simple by just offering help to believers.
No matter if the person escaping to Satellite City is the Saintess or a believer, they're now seen as enemies of the temple and can't be protected by ordinary people; seeking help from Outer Zone players is their best option.
