Shishou was a former traveler who traveled Kino's universe several years ago before settling down in a forest near the Land of Adults. She is considered both scoundrel and savior as she is hailed a hero in some countries and a wanted fugitive in others. Shishou is very adept in military skills comparable to that of a seasoned tactical officer as well as extensible knowledge in situational survival, gun skills, and bartering.
During her traveling years she holstered the 1851 Navy Colt Revolver on her right hip, eventually relinquishing for Kino to "inherit". She traveled with her companion Aibou in an old, dirty yellow buggy that looked like it was going to "fall apart any minute" for her travels.
