This is a Chinese C.G.I based anime probably produced by tencent. The girls look in sexy outfits willing to attack you.Bloody code as the name suggests the crimes occur on the base of this qrcode given.Subtitles are not correctly matched though some ways they are not periodic and overall if you like girls and the hero is a man who doesn't have any goal just wanders and wait for a sexy girl to thrive and attack him but any way he escapes good going anime for mediocre plot based fans.Just a watch an episode for its beautiful C.G.I.
