Katyusha Bosch

About
Katyusha Bosch is the current president of the DX Association; the largest criminal enterprise on The Continent. During the events of Rance X, Katyuscha was approached by Convert Tax, a man who had entered into league with the Monster Army to manipulate Rance by providing sexual slaves to serve him. Eventually she invited Rance to a meeting with the Dark Lord Lei, and tried to persuade him to betray humans and join the Monsters. She tried to trick Rance into signing a magical contract that would force the agreement upon the signatory. However, Rance had long spotted her trickery thanks to the help of Crane. He turned the trap on its head, and gravely wounded Lei with a surprise attack.

Bosch tried to escape, but was stopped by Kanami, Biscuitta, Freya and Caesar. She ended up tasting her own medicine by signing the magical contract to forever obey Rance's commands instead.

Later, it was revealed that she originally came from a rich family. She was cheated and became a sex slave of the DX Association. Using her body and her wits, she eventually got out of the predicament and became the head of the DX Association before the events of Rance X.
