You and the Imperial Flower Combat Revue fought with your mechas against the silver-haired kyoma (demon) Satan and his mech...and you won but...however you noticed your superior officer Ayame Fujieda staggering while resisting some kinda urge due to a demon seed that the kyomas implanted into her...and she holding an object in her hand. She looked pained and desperate while trying to break out of the brainwashing.

You then see the next moment Satan has Ayame and the Majinki hostage. The situation became quite dire. You had one way to save her but didn't know if you should shoot her since you didn't know the properties of the bullet. But approaching her and Satan was just as risky since she could get corrupted into a kyoma. This was bad.
