If Code Geass and Gundam Seed ever has a kid together Valvrave is likely to be the outcome, truly a mixed bag from the beginning until the end. I have marathoned the series from 2 weeks ago until the last episode of the second season that i watched today. I have expected the Valvrave to be disappointing as Sunrise doesn't make any good mecha anime anymore but i am rather sad the good mecha designs are wasted in some worst possible way. Valvrave just shows how High school hijinks and mecha does not mix really well and while the main character is Beta guy, he still got some redeemable factors with him whereas the main heroine represents every worst thing in the anime. Valvrave could have been a decent mecha series but unfortunately most of the aspects in the anime are ended prematurely thus the anime does not have any lasting impression that it could give and i feel the story direction is rather indecisive.
Nevertheless Valvrave still got some redeeming values which is why i said at the beginning it is a mixed bag, L-elf is rather well written character which unfortunately paired with Beta protagonist and the fist fight between them on 22nd episode is some of the best scene in the series. The Valvraves itself is rather good looking mecha and kinda remind me of Aquarion for some reason though i really feel the true power of each Valvraves are not shown in the anime. With how the 2nd season wrapped up it seems there is a possibility for continuity of the series but i am not too optimistic about that either. Nevertheless if Sunrise ever make another mecha series better they abandon the high school BS or else it will not be a good mecha title ever.
