Considering the budget they have, it's pretty amazing how they have gone into an apocalyptic setting.
Takatora walking through the empty city was VERY cool, and I have not seen a global crisis like this since the early Showa era.
They could easily have ignored it and just mentioned that some other countries had been attacked, but no, they actually showed it.
Yuumi Shida's performance in this episode was excellent, and I really hope that she will continue her acting career, because when she is given the right script, she is pretty amazing.
If you haven't done it yet, try looking at her eyes during her conversation with Micchy. She put so much emotion into that scene, and there was a brief moment where she gave Micchy a look, which I think was ten times worse than a slap. I hope I am not the only one who noticed that.
As for the preview. I think it is very predictable what is gonna happen.
Takatora is gonna beat up Micchy, but hesitates during the final blow, allowing Micchy a chance to strike back, and the scene will end with Takatora managing to destroy the Genesis Driver before Micchy escapes.
