Unaired episodes of the Morita-san wa Mukuchi TV series bundled with the 5th manga volume.

Far in the future, where interstellar travel is considered commonplace, high school student Marika Katou balances her duties in the space yacht club and her job as a restaurant waitress. Following a chance encounter with a peculiar pair of customers, Marika meets them again and learns that her absent father has passed away. During his life, he was known as the legendary pirate Gonzaemon. He has left behind his infamous ship Bentenmaru and its crew exclusively for Marika to inherit. With one of the few remaining Letters of Marque that permit legal piracy, Marika must choose whether to stay as a regular student or take up a second life as a high-octane space pirate. As Marika ponders her decision, the delicate situation attracts the eyes of various government agencies and the mysterious transfer student Chiaki Kurihara, all eager to see if the upcoming captain lives up to her father's reputation. If the crew of the Bentenmaru want to maintain their status, they will need to set sail into the vast expanse of space and once again become a name to be feared.

In the second season the story continues exactly where it left off previously. Professor Itsuki's Fermentation Cellar and laboratory is ready for operation and with Sawaki Tadayasu's unique gift to see and communicate with microbes to help, Itsuki's motley group of students begin to process different fermented products like soy sauce and sake.

In 1973, following the ruthless six-year-long Lunar War, the hostile alien species known as the BETA—Beings of Extra Terrestrial origin which are Adversary of the human race—invaded Earth, killing billions and decimating Eurasia. While BETA can be destroyed with conventional weapons, their laser-class is able to wipe out entire aircraft fleets, forcing mankind to develop giant combat suits called Tactical Surface Fighters (TSF) to combat them. When the BETA reach Japan in 1998, military school student and TSF pilot—or eishi—Yui Takamura is ordered to defend Kyoto's last line of defense with her fellow classmates. At the cost of countless human lives and the sacrifice of Yui's friends, the Japanese Imperial Army manages to repel the invaders, leaving destruction in its wake. However, this encounter leaves Yui determined to never again allow something like this to occur. Three years later, now a lieutenant, Yui joins the XFJ project, an Alaska-based Japan-American TSF development program. In an international team composed of the uncooperative Japanese-American test pilot Yuuya Bridges and various eishi from countries lost to the BETA, Yui's task is to help develop the new Japanese TSF Shiranui. Amidst political tensions inherited from the Cold War, Muv-Luv Alternative: Total Eclipse follows Yui's delicate mission and Yuuya's journey to overcome the demons of the past that still haunt him.
