Queen

Queen of all KiseiChu and also mother of Princess and Chacha. She is also the main antagonist of the series. Though her intentions aren't entirely bad due to the fact that the KiseiChu have to feed off H energy to survive. She is also the archenemy of the Hxeros and has the power to control both KiseiChu and those she gives her blood to. (Source: Dokyuu Hentai HxEros Wiki)
