"not even Riruka and Giriko knows of this place"
I'm assuming that Ginjo means that if they don't know, yukio and jackie would absolutely not know.
Making Riruka bascially second in command of Xcution.
GINJO, TRULY A WISE LEADER
And isn't the space invader spy...thing completely incompatible with Yukios power? He absorbs or spits people out of his psp. While they're in there, he can apply video game logic to them. That was it. I don't see how launching video game elements into the real world fits with that.
Isshin sure took his sweet ass time getting out of bed considering he was completely healed when Orihime left him.
