In the opening and several in-episode scenes, there is a MISSING poster for "Sala Powell". These posters are in so many places, I wondered if she is somebody important. Is she?
After a devoted search all around the interwebz, I have come to a sad conclusion that I could not find anything specific about Sala Powell at all.
What I did find during my searching is some potential connections that might help others search, and some speculation.
- This might be a reference to Nate Powell (not very likely). As seen on the linked page, Nate used to be a cartoonist/writer, and also brought out a CD with W A I T called "All The Days Are Numbered So"; this could be a far-fetched connection.
This might be a reference to Chella Powell. After some research, I found out that "Sala" in some languages can be pronounced as "Chella". For Chella Powell, I found the following information quite interesting, but shamefully ended in a dead end.
Advances in Intelligent Systems and Computing #196 by Antonio Chella: The challenge of creating a real-life computational equivalent of the human mind ...
This may be far-fetched as well.
After asking quite some HotD addicts about their opinions, and looking around online myself, I found:
- Sala Powell might be the cause of the zombie apocalypse
- Sala Powell probably has some sort of connection to the apocalypse
- The writer doesent even know
- This is a plot point to be revealed
Points 1 and 2 speak for themselves. She might have been a scientist on some sort of military project. In one of the first episodes, the self defense force of Japan flies over the school, seemingly ignoring all the people flying to a specific point, picking up Sala Powell? Does she have the answer to the apocalypse? Does she have a cure? These points just give more questions than real answers and can't be really proven 'til more of the manga is released.
The 3rd point: Daisuke Satō doesn't even know himself. Satō is a writer known to go on hiatus for a long time due to having no inspiration or just writing himself into a corner not knowing how to get out of it.
And my 4th point, which seems to be most likely for now, is that this is a plot point yet to be revealed. We don't really know much about the apocalypse: not how it started, not what caused it. This might be revealed at a later point in the story. So, until Daisuke Satō makes more manga chapters to harvest information from, I don't think we can have a definite answer.
