Emerald Mempo

The Emerald Mempo was crafted at the same time as the more famous Emerald Armor, but has been worn very rarely because the Emerald Armor and Champion's blade were sufficient badges of the office. It would usually only be used when the Emerald Champion would take the field of battle. The Mempo is a powerful nemuranai.

Shosuro Jimen
The Emerald Champion of 1169, Shosuro Jimen, became the first to wear the Mempo rather than the Armor. Even wearing the Champion's blade is subject to occasion, as Jimen relied more upon his yojimbo Bayushi Hisoka. The mask allows Jimen to remind anyone he meets that he is not only the Emerald Champion, but a Scorpion also. In addition he could remove the mask and no-one would know who he really was; a freedom his predecessors never had.
