Shōga

is the old female flea betrothed to Myōga by their parents. Apparently, Shōga chases her unwilling fiance across Japan, determined to put an end to his womanizing ways and force the marriage herself.

Shōga, unlike Myōga, is able to possess both yōkai and humans, forcing them to act in any way she sees fit. Myōga himself can control birds and other small animal, but only to an extent.

History
In her only appearance, Shōga possessed first Sango, then Miroku, intent on using them to catch Myōga. When Sango attacked Miroku, at first they believed she was sleepwalking, but then realized she was possessed. The group believe it is the influence of a monster centipede, who they slew earlier.

When Inuyasha was possessed, Shōga went after Shippō, on whom Myōga hid. At first Inuyasha started laughing maniacally, then he began hopping like a flea, and then called Myōga's name.

After catching him, Kagome "sat" Inuyasha, bringing him back to his senses. They heard Shōga out, and decide to punish Myōga for his silence by agreeing to force him to a traditional Shintō marriage ceremony.

When the wedding came around, however, they were all sorely disappointed. Leaving a common flea in his place, Myōga escaped. Hot on his trail, Shōga began her hunt all over again.
