This card's name is derived from the Derringer, the smallest usable handgun of a given caliber. They were frequently used by women, because they are easily concealable in a purse or as a stocking gun. This card's flavor text references this fact as this monster being the only female "Igknight" monster.
Ironically, this card has the highest ATK of all non-effect Igknight monsters despite the Derringer being a very small gun.
This monster is modeled after a kunoichi, a female ninja. Her armor is vaguely shaped like stereotypical ninja garb and her weapons are shaped like kunai, a typical ninja weapon. Also her romanized japanese name, Igunaito Derinjā, is a portmanteau of Derringer and Ninja.
