As you look around at your two sisters and the three friends who had been invited over, you had a great idea. With six different girls here, it would definitely be a whole lot of fun to show your new powers to the entire group at once. As you, your friend Kyoko, your sisters Misuzu and Matsuri, and their respective friends Aoi and Kotori reach the living room, you decide to announce your plans to them.
"Okay girls, I have something big to show you all today. I've recently gained the power to control reality at will!"
The other five girls simply stare at you confused before starting to laugh. Then Kyoko steps forward and put her hand on your shoulder.
"Ah, that's a good one Nayuki... So, what's the real surprise?"
"That is the real surprise, Kyoko! Watch this!"
You then proceed to use your powers to grow. Kyoko takes several steps back (and ends up in line with the other four again) as they all simply stare in awe at your expanding form. You continue your growth until your head crashes through the ceiling, and you smile down at the girls from your new towering height of 100 feet tall! The five girls at your feet are still in awe of your new size, and simply stare up at you with their mouths agape.
"So girls, do you believe me now?"
They all simply nod at you, the look of shock still fresh on their faces. You giggle at them and reach down to scoop them up off the ground.
"Well then, how would you like to join me and become the six biggest girls to ever live?"
Misuzu practically jumps with excitement upon hearing this offer.
"Really sis? You mean that you'd make us as huge as you are?"
"Sure thing Misuzu! That's the whole reason why I decided to show you this in the first place!"
You then gently place the five tiny girls back down onto the ground and proceed to grow them to your height. Any sections of your house that weren't flattened in your growth session were nothing but unrecognizable ruins by now. With six giantesses bursting out of it, there obviously wouldn't be anything left of that puny house. Looking down at her feet and noticing this, Matsuri seemed worried.
"Holy crap sis! Mom and dad are going to be furious when they see this!"
You simply giggle.
"Oh Matsuri, have you forgotten already? I can control reality now!"
You then use your powers to lift the other five girls into the air and set them down outside the ruined area that was once your house. Stepping out of the ruins yourself, you then point your index finger at the destroyed house and cause it to return to the exact state that it was in before your initial growth spurt. You then smile over at your sister who, along with the other girls, was once again staring at you impressed.
"See sis? It's totally easy for me to fix things like this! Now, how about we go out and have some fun now!"
All five giantesses scream "Yeah!" in unison, and began jumping for joy. Their little display of excitement quickly leveled some of the nearby houses at their feet. You quickly use your powers to freeze them in midair and reverse the damage that they had done before setting them back down in a safe location. You look at them with a stern expression, and they all immediately apologize. With a sigh, you begin to lecture them.
"Look girls, just because I can fix your little messes doesn't mean that I want to! Please, at least try to be careful, okay? I don't like having to bring back any people that get killed just because you five are being careless! This power may be fun, but it doesn't mean that I'm gonna use it to be some evil ruler of the world or something... Just keep yourselves under control or I'll have to turn you all back to normal, okay?"
The five girls nodded in agreement, and you smiled back at them.
"Good! Now, how do you want to do this? Do you want to go have fun together, split into groups, or just have fun on your own?"
