Hajimari (The beginning)

Izuku life changes that day when he turns four. It changes for the better at the age of seven. Put simply "Deku" has a quirk but it is one that cannot be seen. Excited at the prospect of a quirk he thinks back to how he is treated and sees that in this world a quirk matters more that the person themselves. Finally, neglected he turns toward the dream of being a vigilante named "Dekiru"
