Ok not quite right but I am looking for a manga. The world is filled with animal human hybrids. Basically a disease hits to have mankind use animal DNA to stop from dying. MC is a wimp to have it come out that he is one of the last PURE humans. Oh and to boot he can't have a life without one of his three guards there and no happy time. I can't remember the name but was wondering on the name and if it was still active

Should be this one: Okasu Bekarazu!! Junketsu Tokku!

It's five volumes in all and is completely translated.
