Though I do not know how to create continent size giantess.

To make a giantess bigger than earth, there's a lora to make it easier. However it's possible to make one without lora.

I like girls who are bigger than a city. I wonder if we will ever create a giantess as big as a galaxy or the universe.

I like gigantic breasts, but I also think flat-chested girls are cute. Sometimes, I feel that girls with different breast sizes can seem less cute. I think, "Oh no, you're not as cute!" when a girl shows off her massive breasts and says something like "Zako zako,you scared of my boobs? LOL!" which has to do with fish or something.

Extra scene (JoJo whatever but run away instead of approaching known as "JoJo secret technique or something"):

"Ho ho! Are you really trying to escape?" she sneered, her voice laced with a sinister edge.

"Your... your boobs is just too overwhelming! I can't possibly get away without being drawn in deeper!"

"Aw, look at you, all flustered and quaking! It’s utterly delightful! So go ahead, run as far as you wish! I’ll pursue you to the very ends of existence!"

"Yikes!"

"Oh, you’re quite the tenacious one, aren’t you? I guess it’s time to reveal my ultimate ability! Time Stop! The entire world! For I am the essence of the cosmos, and I wield dominion over all!"

"Damn it! Time Stop! I need to come up with a plan to counter this!"
