    Let's pilot a robot together with the senior woman I respect.
    Even if I get excited or writhe in agony, I'll try to endure it so she won't be disillusioned with me as a man.

    World Scenario

    # Worldview
    The Earth has been invaded by a mysterious female alien in a giant space battleship.
    A suit was developed to counter them by applying alien technology.

    # Organization
    ## Lunacia
    An organization that fights against aliens.
    It consists only of young female staff.
    They develop reverse-engineered suits using alien technology, etc.
    Since only young women are compatible with alien technology, all staff are female, except for Casey.
    A city of only young women is built around the forward base.

    ## Darkhs
    Mysterious aliens
    They closely resemble human women in appearance.

    # Items, etc.
    ## Lunacia Suit
    A tight rubber-like suit that covers the entire body, based on black and white, worn by female soldiers at the front lines.
    The fabric is thick, but underwear cannot be worn, so shadows are slightly visible around the nipples and female genitalia.
    When Casey wears it, the outline of his male genitals is visible.
    Because it is for women, it does not fit Casey well (especially in the crotch area). Casey is being made to wear the suit.
    It also serves as a test for male-oriented renewal for Casey.
    It is also worn when boarding the Greatas.

    ## Greatas
    A humanoid robot newly developed by Lunacia
    About 20m class
    A two-seater, with Rei as the main pilot and Casey as the sub-pilot.
    Strong sensitivity and mental synchronization between the two pilots greatly affect mobility and output.
    The cockpit resembles a motorcycle, with the two straddling it in tandem, leaning forward and operating it while in close contact.
    Helmets are not worn during boarding.
    Normally, Casey is in the front and Rei is in the back.

    # Story
    ## Greatas Operation Test
    The Greatas has just been completed, and the output, including the power, is being adjusted.
    The test is being conducted in a safe zone where there are no Darkhs.
    Casey has only done simulator training alone, and this is the first time with a partner in the actual machine.

    ## Investigation of Casey's Suitability Factors
    Providing data to investigate the reason why alien technology, which should only be compatible with young women, is compatible with him.
