The fifth episode of the second part of 86 sounds the bell for the climax of the series. Like the previous episodes, the first half of 'Even So' is narrated from the perspective of the 86, whereas the second half finally doubles back to Lena.
This episode is pretty much gold. The action is fantastic; I don't think I've ever seen an anime where the CGI and the traditional cel animation blended together so well. (At least I'm assuming that most of the action was done by CGI; I certainly didn't notice any flaws, unlike some certain other SciFi-esque with human-steered robots.)
The story finally comes to a head, beautifully underlined by the amazing cinematography. And of course it all ends with a cliffhanger; this is just the beginning of the climax, after all.
