The main girl may have plot armor so heavy that the space shuttle couldn't carry it. Or so someone in these very comments mentioned very early in this story. IDK if I believe it since it would take an act of God (aka the author) to prevent her from being ... violated in this situation.
Also, I'm very sure that Gamou saw that drone. He's not that dumb. Even if he didn't know what it was he would at least know it wasn't natural. He could have set this up to draw out the idiot that was shouting at the festival about saving Aoi. Come on stupid ... show your face so I can rip it off.
Also, also We all know this MC is dumber than a case of bricks (I don't mean to slander bricks), a bunch of mackerel, and some corned beef (who both locked themselves in a can and put the key on the outside). I've lost count of the number of times someone had to literally stop him from getting them all killed ... or even worse violated.
