Well I've been looking forward to this Anime since Xebec is making it and they have had no memorable release since their first anime back in 1995 and so far it's alright.
Despite for Anilist's low rating of 68.9 it's pretty good. I've liked all the blood so far in it and hopefully it will continue to have this serious side to it.
However I couldn't think of anything else except daft punk when they were raiding that parliament building due to the ridiculous masks they had.
The animation is also really well done so far and I will continue to see high expectations for this in the future.
