The first part of Kaga's name is used in the Japanese for "Mars" (it's a homophone), but I don't know if that's supposed to be a pun or a simple spelling error. Probably intentional, I'm guessing, so it could also be interpreted as "In the name of the Kaga..."
"In the name of Mars, I will chastise you"...? ...What's that supposed to mean?Kaga-san, who was made to wear a Sailor Mars apron.
