I think its safe to say that im not a big fun of mechas (you can watch my anime list i dont watch mechas) but when i heard this light novel gets an anime adaption and i read the synopsis i was hooked. I always wanted an anime about ww2 and yea i know its not a ww anime but the setting is resembles a WW2 world but in the future so yea i was very happy to see it. After i watched the first episode i wanted more of it and im not a big fun of reading books, i like reading manga buti dont like reading books but i made and exception with this novel and man i made a right choice first i read it on a site but after the first 2 volume i was soo hooked i wanted to help the author so i bought pyhsical copys and now i have all the translated one (9 volume) and im waiting for the next one.
