You are a young researcher at a uni lab often working long into the night on a device together with your colleague, Eva. The project's purpose was always to help people sort out their brain... But the day of the first test, you two realized the device makes them obey your will instead!
And just as you figured that out, powers that be did so too and are now after you! They kidnap your colleague and almost get you, but you manage to run away and go into hiding...

But you are not alone in that, and now you live with a group of scientist girls each of which has also invented something powerful...
