Okay, so it’s a mecha anime and in it the main character is a female teen who’s mom works at this research facility and one day while she’s visiting these things drop to earth that her father called like goblins or something but they’re actually robots. So when that happens this boy wake up out of this giant black box and mistakes the main character for his princess from thousands of years ago. He then takes her and has her pilot this giant robot with him. Please help! I really liked this anime! The main character had short brown hair if that helps
