This time there were no robes, no hoods, no masks. Students were expected to become friends, and allies. And everyone knew why you were in the classroom. It would have been pointless to pretend you weren't in the Conspiracy.

Their sensei was Jeffreyssai, who might have been the best of his era, in his era. His students were either the most promising learners, or those whom the beisutsukai saw political advantage in molding.

Jeffreyssai's expression was kindly. "Hiriwa, it wasn't religion, and it wasn't lead in the drinking water, and they didn't all have Alzheimers, and they weren't sitting around all day reading webcomics. Forget the catalogue of horrors out of ancient times. Just think in t...
