You do keep in mind when reading the two books Akyu published that they were written to help protect humans in the village, and so probably contain exaggerated reports of danger. You also keep in mind that as a were-hakutaku, you're somewhat more resilient than the average human. However, you do realize that it might not be a good idea to get anywhere near someone who can spread infectious diseases, especially if you plan on returning to the village.
Out the corner of your eye, you see... someone next to Kogasa hand her a small, clear crystal. You can't tell who, because you can only see the hand, but you think you caught a flash of blue clothing. Kogasa seems to be waiting only for you to turn away, now.
(Choice is up to you, but I won't recommend it. Just keep in mind the potential consequences, as Keine would.)
