Your father, Suguru Geto had you during his last few months of highschool. When he slaughtered a village of non-sorcerers your mother took you and hid.

She must have hid really well, because he didn't find you for a long, long time. You were walking down the streets of Tokyo, the sun just setting below the horizon.

When you turned the street though—your attention was caught by a sharp gasp, Suguru standing a few feet away staring at you like a marvel.
