Izuku goes missing after parents die. However he managed to find a plantation/lab underground with a singular Franxx within. This was the personal lab of the creator of the Franxx, Dr. Franxx himself.
around 5 years after he left, klaxosaurs appear across the globe. Safe havens were made for everyone, including UA being one. another 4 years later, and UA is about to be attacked. However, what everyone across the world sees, is a Franxx stopping the horde from attacking and gives hope to everyone.
Will Izuku be able to handle the pressure being the Symbol of Hope and pilot Humanity to victory? Or will he crumple under the weight and Humanity dies due to the Klaxosaurs?
And how will UA feel when they find out the pilot of the franxx took an experiment to gain powers and have half of his biology become that of what Humanity seeks to kill?
