In this story I'm aging the people of a certain scientific railgun by 1 year. But touma, index, motoharu, and other characters in toumas class are the same age as before. For plot reasons. Ben 10 moves to academy city to establish a plumber base in the futuristic city. And to add on to his list of problems Azmuth drops off three 5 year old girls with the minds and body's of 12 year olds who are also bens little sisters/clones. Mikoto misaka is the third strongest esper in academy city. She meets Ben after being saved from aliens by him. Not long after she starts to feel something for the strange and heroic boy. Could it be love? I DO NOT OWN ANY PICTURES I USE IN THIS. I MAY MAKE A COLLOGUE OF PICTURES BUT I DO NOT OWN THEM. ANY PICTURE THAT I OWN AND I CREATED (with help from other pictures) I WILL INDICATE AND STATE THAT I MADE IT. I WILL ALSO STATE THE NAMES OF THE ARTIST WHO CREATED THE ORIGINAL VERSION BEFORE MY EDITS AND COMBINATION WITH THE OTHER PICTURES. MINOR EDITING FROM TIME TO TIME.
