Shortly after the series ends, Kotetsu and Barnaby revive their partnership and begin a romance. Kaede's untimely arrival and Kotetsu's overreaction to her new plans interrupt that. In order to survive, Kotetsu and Barnaby's burgeoning romance would have to be foolproof.
During a mission in space, Kotetsu has a vision of the future. In this future, he and Barnaby face an old enemy in a new guise, but the future soon bleeds into the present. No matter what may come, Kotetsu vows to remain Barnaby's constant friend.
