There are several retirement cartoons for women that focus on themes like relaxation, hobbies, and newfound freedom. For example, some show women traveling or pursuing creative interests.
Honestly, I don't have exact details on the new developments in Ysio manga. You might want to keep an eye on official manga channels or fan communities for the latest updates.
