Shozen

Shozen was an opium addict who alongside with Tsukai manufactured opium which was later sold in the opium den of Mimura. They brewed a strong beverage they called Pennaggolan. The poison was made from the root of a local plant, tane, which they found in the Forest of Reflection. During the nightmarish illusion it provoked, the victim was open to suggestion, and could be convinced to do almost anything.
