This 4-koma about the adventures of a flatchested demon princess has a bit of a history. It was translated by Mtzy way back in 2010, sat on someone's hard drive for two years, and was finally finished by HyouRetsuzan as his first edit. Congratulations to Hyou, and best wishes Mtzy, wherever you are!
