The avatar and sig is a set that came from a panel of the last chapter of a Shoujo Manga, Sukimi Shiki like I mentioned on other few thread. It doesn't mean any harm to others as I see this in a ironic comedic way.
The last line of the Witches Epitaph and Riddle in Umineko said to reveal the location of the 20 Billion Yen worth of Gold.
Siggy image is Beatrice cause the "Witch" the Epitaph revolves around is her.Beatrice, The Golden Witch.
The line also is a code.Feel free to try and solve it
Mine is fan art of Sesshoumaru and Kagome from Inuyasha :3 I've shipped this pair for years and recently started reading (or re-reading) a lot of fanfics. I'll switch it when I get tired of this topic and move to something else~
