Some years later, when the two of us were out playing—

Suddenly, we were outside a building in a place I didn't recognize.

He said he was the eldest child of the Togakushi line from the Jingo-keiun era... that is, 200 years earlier.

He'd studied taboo magic by himself, running off while he still had the heart of a child... living in the capital and on Mt. Shigi for a while.

Eventually he'd grown tired of the inactivity, started to wander the earth, and ended up back home. He told me all this.

That was the first time I knew.
