I want to find out why the hero is so fast and strong, despite not using any coils. Hope there´s more to it than "it´s anime, duh".

The robot girl seemed way sexier in this episode. Before I had perceived her as a loli character, but she was super busty and, well, standing next to actual children helped. If I was the hero, I´d have her every night ;>

The overarching story seems obvious imo: The entire economy depending on coils will backfire, when we find out more about those "deep coils" aka numbers. The W-dimensions is bound to be more than just a source of infinite energy. While the hero seeks the guys that killed his parents or whatever, he finds more information about numbers, and thus gets closer to the dark secret behind New Tesla Energy. Which, if we´re in for a happy end, ends with the whole world going back from NTE to good old oil and gas (lol).
