Right after the Heroic BSOD seen in Episode 10, the show continues with it’s cliffhangers in this episode. The animators are probably thinking: “Have your Christmas in suspense”.
Anyway, Shu finally figures out he has to do things his own way, and not mimicking others (like every other hero did in other animes). Finally more main character-ish, it was especially enjoyable towards the end, with numerous voids popping up. Oh, and Buggies>Mechs. XD
