On his way back, he spots Laura talking with Chifuyu, begging her to return to Germany and that the IS Academy doesn't deserve her, but the latter doesn't listen. It is revealed when Ichika was kidnapped during the 2nd Mondo Grosso IS championship, Chifuyu forfeit the finals in order to rescue him. Upon returning to his dorm, Ichika walks in on Charles in the shower to discover he is actually a girl. Charles reveals she is her father's illegitimate daughter who was taken in after her mother passed away and made an IS test pilot. But when the Dunoa corporation entered a financial crisis due to the demand for third generation ISs, Charles was ordered to act as a boy to give the company publicity and steal data from Ichika. Ichika empathizes with her as his parents abandoned him and Chifuyu, thus deciding to keep Charles' secret as she'll be safe at the IS Academy due to diplomatic immunity. Meanwhile, Laura, who blames Ichika for blemishing Chifuyu's record removes her eyepatch, revealing a golden left eye and swears revenge on him.
