So dude just barged in despite the police? Could made the hijackers freak out and shot them both! The kidnappers spent a lot of money organizing the hijacking?! For what? They drove her to some warehouse nearby!
With the author starting to include more "serious" situations (although stupid and nonsensical) the original appeal of this manga got lost, imo! From an almost parody of the genre we are slowly getting a usual cliche isekai! Such a shame
