Rance is the eponymous character of the Rance series of games. His surname is unknown. On a note of sexual innuendo, the term "Lance" also translates into the identical Japanese word.
Rance is a skill level 2 swordsman. A kichiku warrior by nature, he is motivated by sexual instincts instead of love or justice. He lives in the a small town named Ice, of the Free Cities, and is member of the local Keith Guild, taking on various odd jobs when money runs out. He has a slave named Sill Plain, and owns a humanoid artificial lifeform named Athena 2.0.
His heroics have saved three out of the four major nations in the Continent from being conquered by Dark Lords, as well as helping quite a number of damsels in distress. On the other hand, his impulsive sex drive has, to put it extremely mildly, scarred quite a number of young women for life.
He is very uncomfortable in the face of romance from other girls that end up genuinely falling in love with him, especially evident when Uesugi Kenshin confesses to him during the events of Sengoku Rance.
In one of the non-canon endings of Sengoku Rance, Rance has rallied Leazas, Free Cities Alliance, Helman, Zeth and JAPAN against the demon army in The Demon Realm
