Subaru Ichinose is deeply attached to his cockpit as it reminds him of being inside his mother's womb. Whenever he faces difficulties communicating with other pilots, his cockpit becomes his sanctuary where he can be alone. As the ace pilot on board Tiramisu, Earth Union's most crucial battleship, Subaru is responsible for safeguarding Mother Earth from threats that arise due to humanity's expansion into space. Armed with Durandal, his personal mecha, Subaru must defend against encroaching foreign colonies while protecting his own sanctuary from unwanted elements like rogue fried pork skewers, suffocating backwards shirts, and unsolicited redecorations. In Space Age 0156, the future of humanity rests on Subaru's shoulders.
