To my son that I have never met,
This is your biological father writing. If you have received this letter, it means that I did not make it. I have instructed your mother that if anything happens to me, she has to deliver this letter to you on your 15th birthday. At the time I’m writing this, you, my son, have not been born yet. But in 15 years, I imagine you grown up to be a strong handsome son, both in body and spirit. And now it is time for you to know who I am, your father, and about my past.
I am a soldier in the Storm Squadron of the Earth Defense Force infantry. I have no name, I’m only referred as Storm 1. I have no special abilities, no special talent, no special power. I can carry only two weapons at a time with unlimited ammunition, and I do most missions on foot. I’m also qualified to pilot these following four vehicles, but I hardly use them: the combat tank E551 Gigantus, the SDL2 Airbike, the combat helicopter EF24 Bazelato, and the battle mech Vegalta.
