The exchange student

Giants were thought to be myths, in a way they were until Portals started opening every where and giant humanoid creatures emerged, over 150 feet tall in height, they seek get rid of the planet original inhabitants so the humans fought bravely but lost due to massive size gap, and more advanced technology, but when It seems it was over for the humans, the creatures vanished. months later they reappeared and came to an agreement with the human leaders, once a year a celdens ( name of the creatures ) is sent as an exchange student to the human school and a human is sent the giantess school, this is to somewhat learn more about each other but things didn't go well first try, the humans never come back alive, most of the human student in the school that the giantesses sent to never survived, they kinda went with it that way, it was either that or they wiped out from the face of the plant. summer pine high was chosen this year.
