Disguised Magical Girl in Relotos

My name is Dusk, and I have traveled through time. Good news: I have become younger, my face has become more beautiful, and I am often complimented on my beauty when walking on the street. Bad news: pretty as a girl. More bad news: I really am a guy. In order to survive, I was forced to enter an all-female mecha academy, put on a skirt, tied up my hair, and became a special admissions girl. Do you think the next one is Long Aotian's script? No, what comes next is hell
