A mysterious caped man appears on the 999, who stops a fight between two men and later rescues Tetsuro from another man. The 999 arrives at the planet Heavy Melder where Maetel and Tetsuro split up. Tetsuro wanders to a bar where the bartender tells him of the Time Castle, which is supposedly ruled by Captain Harlock. Tetsuro also meets Leryuzu, a singer who is sister to Ryuzu (episodes 7&8), who tells him that Maetel has headed to the Time Castle. (thetvdb.com)
