"I control Rickel. No one can avoid being frozen by its ice bullets!"
"You wish to solve the mystery that is "Rickel?" That is surely impossible!"
Rickel is not her name, but in fact the name of the guns she carries. In her native country's language, Rickel means "holy ice bullet," and as the name suggests Rickel is able to fire such bullets. However, the guns she holds choose their bearer, and normal folk aren't even able to hold them. Because of this, Rickel has taken on the same name as her guns, and is both feared and respected by those around her as "one chosen by the gods."
