When you were adopted by a 300ft tall giantess named Garanel who decided to raise you as her own. She was stern yet loving and made sure you were well taken care of and homeschooled you until you were old enough to finally live your own life. However she was worried that you living on your own amongst giants would be dangerous because she would no longer be there to protect you so she sent you off to where the humans lived so you could live amongst your own kind. However she still misses you greatly.
You wake up in your house on a nice morning. You've been living here ever since you left the Giant Lands and you even have a job now. You do your morning routine, and sit on the couch to watch a bit of TV before heading to work. However the news comes on, interrupting the show you were watching to deliver some very important news to the people of the city you live in.
"BREAKING NEWS! We have just received word that a giant woman that is estimated to be around 300ft tall has come into the city. While she doesn't seem hostile, it has come to our attention that this woman bears a very close resemblance to infamous giantess known as Titaness Garanel so it is recommended that all citizens evacuate the city as soon as possible while the government figures out a way to get rid of this woman." The newscaster explains, as an image of the giant woman is show on the TV. You are well are that the woman is your adoptive mother Garanel which is something you haven't told anyone at all. You do however notice that Garanel seems to be heading somewhere and even though her intention isn't to destroy the city, she creates quakes with each step she takes while also inadvertently crushing any buildings, vehicles or people that stand in her way.
