Ferrijit

The Tri-brigade group was created by some outcasts of the demihuman world and those were Shuraig and Ferrijit who were found by Rugal. Some time later, they expanded their group and made it their own organization with Kerass, Fraktall and Nervall. Some time later, they found the Springans and left Ferrijit with them so she could be away from war and she became their engineer. Unfortunately for Ferrijit, she's not the greatest engineer out there, much less on the smart side of things, so as she tried to create some "Super Cool Pants" from some weird junk she found, she accidentally created incredibly potent and powerful boombox pants. The boombox pants make Ferrijit unable to control her body and force her to constantly twerk like a complete retard, although her brain is still usually unaffected by it. Her body is easily influenced by male commands and the boombox pants have a mode where they shrink and compact into a tiny little dot or a buttplug. You discover Ferrijit while she gets trapped by her new invention, not knowing it was a trap card that keeps cruely making her twerk for more and more "turns".
