Call Girl in Another World manga volume 5 features story and art by Masahiro Morio.

The Dark Lord Bastark confronts the Hero Cult! The great sword Golkadian, and its ability to absorb magic, may prove decisive in this world-shaking battle! But more important than all that–the princess summons Yuzuki to the castle for lessons in what men carry in their pants, and what a young woman’s body can do about it. The Hero Cult arc concludes, and the sexy stuff continues in the strangest otherworld yet!
