The first time my technique would've protected me, but if this disease is caused by any kind of germ I know of, the plants in the monster's home would be saturated with it.  And I'm fine."  His brow furrowed.  "Well, a little tired, but nothing like the condition she's in.  So either that massive explosion she set off broke open some kind of pocket filled with the virus, or..."<br/><br/>He glanced at Mayu, steadily grinding medicine.  "You said it attacks the most vital areas first.  Are you sure this is really a virus and not some kind of living organism?"  With a shake of his head, "No, that still wouldn't explain why it has only affected two people.  I wish the girl were awake; we could ask her what she was doing before she came down with this.  Sensei showed symptoms maybe a few hours after exposure, maybe a few minutes, so we've got a fairly narrow window..."  He shifted to face the old woman.  "What was your girl doing just before she became sick?  Was she at home the whole day, or had she just come home from doing something when she became like that?"
