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.

History
Shōga, unlike Myōga, is able to possess both demons 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.In her first and final appearance, Shōga possesses first Sango, then Miroku, intent on using them to catch Myōga. When Sango attacks Miroku, at first they believe she is sleepwalking, but then realize she was possessed. The group believe it is the influence of a monster centipede, who they slew earlier.

When Inuyasha is possessed, Shōga goes after Shippō, on whom Myōga hides. At first Inuyasha starts laughing maniacally, then he begins hopping like a flea, and then calls Myōga's name.

After catching him, Kagome sits Inuyasha, bringing him back to his senses. They hear Shōga out, and decide to punish Myōga for his silence by agreeing to force him to a traditional Shintō marriage ceremony. When the wedding comes around, however, they are all sorely disappointed. Leaving a common flea in his place, Myōga escapes. Hot on his trail, Shōga begins her hunt all over again.
