This 10-episode OVA series acts as a companion to the Irresponsible Captain Tylor TV series; it contains three different volumes ranging from two to six episodes each that take place at various points along the timeline of the original series. Two episodes are devoted to a story that takes place after the war is over when it is discovered that the Raalgon Empire has developed a new and dangerous weapon. There is a six episode volume containing a story about a friend from Azalyn's past, stories about Kojiro and Andressen testing new prototypes, and a Christmas episode. The third volume draws the entire Irresponsible Captain Tylor series to a close with a dire new situation to resolve and most of the crew dispersed or reassigned.
