A clone of Yohko, created by Zenga using the Old Timer's Inheritance. Although biologically a girl, Zenga seems to have brought Yohsuke up to be a man. She first appears in the series as a young child, to observe Yohko's life. Later Yohsuke appears in the series in the guise of a man, and joins Madoka's class on the last day of school. He also has an obsession for fish-paste sausages, possibly a Freudian expression of her desire for a phallus (or maybe just a masculine counterpart to Yohko's ever-present Pocky). Due to their similar, strong personalities, Yohko and Yohsuke do not get along with each other. Madoka has a crush on him, not realizing Yohsuke is a clone of Yohko. An accident later turns Yohsuke into a man biologically. He then becomes an apprentice to Ayano's grandfather. Yohsuke pilots a copy of the TA-29. However, Yohsuke's ship uses a 500-yen coin instead of the 100-yen coins Yohko uses in her TA-29.
