Farewell, Days of My Youth

Inuyasha and his companions, after facilely defeating a demon in a town, are invited to a banquet as a reward. Oddly enough, Myoga the flea youkai servant returns, as series of strange occurrences ensue. Sango, Miroku, and Inuyasha are all possessed one after another, experiencing unorthodox behavior. Little do they know, Shoga, a female flea yōkai, is responsible for this, all in the desire to marry Myoga.
