Siblings Drash and Aica become increasingly interested in trying out G-Milk Co's more extreme products. With G-Milk usage becoming more popularized in society around them, it further tempts the two's lustful interests in turning into something truly desirable. Luckily enough, Aica makes fast friends with a traveling G-Milk employee, Solar Delton, and is able to obtain a "mystery potion" with his help. Incidentally, Solar sneaked this particular high-end potion from an upper-level employee, and neither of them seem to know what this potion does... but given where it was sourced from, surely it will satisfy the sibling's needs...?
