Accidental

Five: Waiting

Shippo went back to the fuedal era.

He had fogotten to leave the Jewel Shard in Kagome's time, so the Jewel was made whole.

It was used to banish all the demons except for Shippo. Don't ask how it made the distinction, it just did. . .

Sango boare Miroku's child, a boy, and Shippo guarded him after Sango's death.

Somehow, Shippo always stayed with the family of this friends.

Over time, Miroku and Sango's decendents became the Higurashi Family.

Shippo was there for the building of the Shrine.

He was there even after they'd forgotten him. Secretly, watching, in a multitude of forms. He'd perfected his transform power long ago.

Sometimes, he made himself human, and enfolled in a school.

But most of the time he simply watched through windows.

And for five hundred years, Shippo waited.
