So, for all the times Miroku has managed to suck poison into his kazaana (you know juuust enough so that he gets sick but doesn't actually die from it), wouldn't you think maybe he could start building up a resistance to it?
...Well, okay, probably not. I really don't know much about that whole subject except that it is possible to do for at least some kinds of poison.
Aw, no more takers for this thing? Do you need hints? I guess I can do hints.
