Machine Girl: School Belle? I Directly Control the Beautiful Principal

[Mecha + system + machine girl + funny + passionate + single female protagonist + weak introduction] Ye Yifan accidentally traveled to a different world. In order to fight against the monsters of all races, the human race started the mecha era... 18-Year-old boys awaken as pilots, and girls awaken as mecha masters. At the awakening ceremony, Ye Yifan's talent was only F-level. He was broken up by his school beauty girlfriend and expelled from the family. Being struck by lightning, he awakened the most powerful mecha system. In order to complete the task, I just confessed my love to a passerby. She is actually my principal? "What's the point of talking about school beauties? All I'm talking about is the principal!" "Can you please be gentle when you come in? I'm your principal!" "I don't want the school beauty anymore! I will directly control the SSS-level beautiful principal!"
