When the magazine Champion Red Ichigo folded, it took more then a few good manga down with it. Unfortunately, Rescue Me! was one of the ones cancelled as it never moved to another magazine. It only got to run for four volumes, but it probably could have ran for a few more. A kind person got around to finally uploading the final two volumes a few days ago.
It got an OVA a few years back, and Wizard made a fanservice compilation worth checking out.
For those who haven’t read any of the translated chapters, this manga is much better when understanding the context that the pettako blonde twin-tail is actually the MC’s aunt.
It was written by Makita Yoshiharu, but he doesn’t seem to have written any other ecchi manga after this had ended, though he does have a couple hentai.
