Mahiru Shirota firmly believes that simple is best and troublesome things should be avoided at all costs. It is troublesome to do nothing and regret it later—and this ideology has led the 15-year-old to pick up a stray cat on his way home from school. As he affectionately names the feline Kuro, little does he know that this chance meeting will spark an extraordinary change in his everyday life. One day, Mahiru returns home to find something quite strange: a mysterious young man he has never seen before. His subsequent panic results in the uninvited guest being exposed to sunlight and—much to Mahiru's shock—transforming into Kuro! Upon revealing himself as a mere lazy shut-in vampire, Kuro promises to leave once night falls. However, one disaster after another leads to Mahiru accidentally forming a contract with his new freeloader, dragging him into a life-threatening battle of supernatural servants and bloodthirsty beings that is anything but simple.

Subaru Ichinose loves his cockpit as, to him, it's like being in his mother's womb. Whenever he struggles to converse with his fellow pilots, his cockpit is the one place he can be alone. As the ace pilot aboard the Tiramisu, Earth Union's most important battleship, it is his job to defend Mother Earth from the threats that emerge from humanity's extended dominion spreading throughout the vast reaches of the universe. Armed with his personal mecha Durandal, Subaru must fend off encroaching foreign colonies as he struggles to protect his personal sanctuary from rogue fried pork skewers, suffocating backwards shirts, and unsolicited redecorations. In the year Space Age 0156, the fate of humanity rests entirely in his hands.

Second season of Uchuu Senkan Tiramisù.
