So, why CAN Ichika pilot an IS?
Tabane wants him to get hooked up with shittiest girl
Because Tabane used Chifuyu's genes when making the first IS and then used them for every IS after resulting in only women and Ichika being able to pilot.
Now think how much better IS would be if Ichika was Ichiko.
Houki best girl
Thread needs more Houkis
That because He is a little girl at heart.
