67 Percent Inertia

A cringe-inducing, slightly sexy college student comedy.

This is a story of four college friends, who get into cringe-worthy situations with a bit of a risque element.

Currently serialized in Ultra Jump (as of like, May 2015) this is a manga by Shimimaru. I enjoy it.

Characters information and downloads

You need BitTorrent to download the translation. BitTorrent is common enough now that you can probably find your own client. I prefer Vuze myself.
