Once upon a time, a little girl named Fuka asked her father to have a little sister with advanced functionalities strong enough to help her take over the world. Several years later... The Prototype known as the "Death/Extermination Submersible Combat Organism" was born (Desco for short). Unfrotunately after DES X was created she ended up being abandoned and was sent to Hades where she was locked up under high security.
She was later released by Axel, thinking that he could control her. Unfortunately Desco takes out Axel in one shot to show how "Final-Boss like" she is and proceeded to fight Valvatorez, Fenrich, and Fuka (the latter being Desco's Illegitimate Big sister (spoilers))
After being defeated, Valvatorez decides to bring her Desco along. She now trains under Valvatorez to achieve her dream to become a "Final Boss". One that'll be able to help Fuka take over the world.
She likes to call Fuka "Big Sis".

- Final Boss Arises- The Thing on Desco's back opens it's two mouths and blast two cyclones on the enemy (One that's ice and one that's fire).
