Episode 93

The Mysterious Lecherous Monk is the ninety-third episode of the InuYasha anime.

Synopsis

 * 1) As Inuyasha and the others continue their journey, they come upon a village whose inhabitants claim to have been scammed by Miroku a day before; his friends eventually realize that this is impossible, because Miroku had been with them the entire time, meaning someone must have been impersonating him.
 * 2) Miroku soon deduces who has been impersonating him, saying that it is someone who knows him well.
 * 3) Hachiemon proves to be the culprit, claiming that he only impersonated Miroku because he was dying of hunger; he promises to never do so again.

Summary
Miroku and his friends come across a village which seems to remember him, but that he doesn't remember. According to the villagers, Miroku came and went only days before. Miroku then realizes that someone is impersonating him, and is doing a fairly good job of it, so it must be someone he knows well.
