Japan: The Home of the Daibijins The Daibijin: Demolition Girl chapter 4 by GiantessKaijuFan

Riho Futaba may be a colossal bikini-clad monster living up large in Japan as its Godzilla, but it turns out that she isn't the only one who became a kaiju. During the year she was adjusting to becoming a kaiju and a mega-celebrity, it turns out there is even more giantesses like her, and all have similar traits and powers like her. They too were reportedly bitten by an alien crab just like her, and they grew to 30 times their normal height. (side note, I did the math on Riho Futaba's 48 meter height, she was 1.6 meters, and she grew 30 times that height, and in feet she is 157.5 foot tall, so any new characters, times their original height by 30). Unlike Riho, some develop other powers like flame breath, and the such. Apparently the alien crab (or crabs) was busy making women like Riho gigantic.

Well, during the year, more giantesses like Riho appear with different powers, and even more funny enough, the people of Japan was so happy having their giant monster in Riho, that they didn't mind having more monsters like her now. Japan of course struggled to adjust to having more giantesses, but they made it work in alot of ways. They had to live on Monster Island, but was free to visit Japan to become its monsters for entertainment. Some went to join the JSDF to repel monster attacks and rogue giantesses, even embracing themselves as kaiju protectors, and some do various businesses like modeling and such on a colossal scale.

Eventually, this got the Japanese government an idea, they would take advantage of the new Daibijins as they dub it to promote Japan as a to be destination. Riho even was delighted to have some new friends who are gigantic like her, and even some rivals as well, as she can't be the only competition in being a giant monster, and might as well give the people of Japan and the world a show. Soon the city was adjusted to let the giantesses walk on the roads without the worry of crushing anything, while also giving them the feeling of being gigantic in the city as its monsters. The various Daibijins would be promoted like actual kaijus, some with their own monster names as well which they use for marketing. There is so much that can be say about Japan now, that they basically fallen in love with the Daibijins, and now they are embracing the giant women as their monsters, with Riho being the spear head in it. They even have a stadium where the women compete in events, including kaiju rampages as well (with monster battles as well)

During the year, Riho has helped them adjust to being gigantic and using their powers as well, and they are similarly aged idols like her (gonna have a variety of giantesses here to embrace the silliness of it all) Riho was willing to help them live a life of being a colossal titan, and she loves every minute of it.

So what should we do with this new story element here? Focus on Riho, perhaps a different Daibijin in their own storyline, maybe a new character who lives among the Daibijins (who are dubbed as kaijus), the possibilities are endless.
