When Mikoto and Kuroko had a female-female union, giving birth to the Level 6 "Super Electromagnetic" Misaka Miko and the Level 5 "Space Controller" Shirai Kurorei, Academy City inevitably met its end as an autonomous city.

I am Fang Han, the representative product of the Dragon Country's research into quantum technology and ability users (biologically male, but can be female). Yet in this self-governing city, I discovered that my "quantization" ability was strange beyond belief...
