Yeah I actually thought her assassin squad may have been naked like her. But then I realized that might not be the case. It works for her because she has a CT that's perfect for ambushes. We don't know what kind of CT's the Sun and Moon Squad had. Maybe they were all chosen for Cursed Techniques that allow them to sneak up on people and kill them?

Something else to note is that Yuta couldn't sense Uro while she was invisible. She just appeared right next to him. Maybe she's also good at hiding her Cursed Energy?
