Awesome / Hogyoku ex Machina

  • Ichigo defeating Aizen with nothing more than a simple sword strike, similar to the one that sent them back in time. Also doubles as a Crowning Moment of Heartwarming, as he used Muramasa to do it.
    Ichigo: "Do you know the difference between me and you, Aizen?"
    Aizen: "I am pleased to say that there are too many to count, Kurosaki Ichigo."
  • On a meta level, the story itself. In the author's own words, it stars "an obscenely overpowered time-traveler with a second zanpakuto" and "got away with it".
