Obviously this art is NOT mine, all credit goes to their (talented) owner. I just wanted to share it because I think it's one of the best fan arts of our girl Shinoa. 💜
Oh yeah, sorry for never answering your question. i just randomly came across those images on the internet, can't exactly say their specific source. I'd say search "Owari no Seraph memes" on Tumblr, cuz i know at least one of those came from there.
