Headscratchers: Fight Ippatsu! Juuden-chan!!
- Why didn't they just deactivate their stealth-mode when Sentou couldn't see them?
- Because they don't want other people to see them?
- As I understood it, people normally couldn't see them regardless of stealth mode; stealth mode makes it so they can pass through objects and move about without having any effect on the world besides what they're supposed to do. That's why Plug at one point bumped into a guy without her stealth, and the guy had no idea what'd happened because there was nothing but air where he was looking.
