Giant Ojou-Sama

i can't believe my ojou-sama is so huge! fujido oriko is the buxom young head of the fujido zaibatsu, a group that has a monopoly on japan's vending machine industry. and serving at her side is her personal butler, the eccentric dr. sebastion. when a monster suddenly attacks the city, dr. sebastion slips his ojou-sama an experimental energy drink his team in r&d has been developing. as a result, she quickly finds herself growing into a giantess, matching the attacking kaiju in size! will she be able to stop his rampage, or at the very least, keep her dignity intact?
