The elusive Gunsenrosen is a huntress of the streets, sneaking from dark corner to dark corner in search of prey, slaying the Johnkaterpillars and other vicious beasts of Tick-Tock Town without mercy. She is a master of the art of surprise, and is rarely seen by those not looking for her. Anyone who desires to find Gunsenrosen has to be as sly and cunning as her, and serve as her equal in combat. But those few who earn Gunsenrosen’s respect make themselves a powerful ally in the city. She has been known to go so far as to take those lucky few under her wing, training them to fight the monsters that prowl the streets. The lucky few who become her protégés are rarely if ever seen again, but are assumed to have either died or taken the streets as their personal hunting ground as their mentor does.
