Like in Tenchi Muyo almost every female character is interested in The Hero. ...Poor guy.
When greeting Kazuki for the first time Sanada is a little too... enthusiastic. Both Times!
Ken Sanada: I'm overcome with emotion! You are the Chosen One, aren't you? And you even feel good! I love it! He's the Chosen One and he even feels good, too!
Kazuki: Help! Somebody! He's a pervert!
Then when Ken's second in command wants the Auto-File of the incident where Kazuki first piloted the Giant Robot. Ken sends her a audio file from a porno.
"We interrupt this program to bring you the following announcement, paid for by The People's Committee For A Chaotic Overthrow Of This World By The Rara Army."
It's great how they can take something that you'd expect would sound threatening, and make it funny.
Poor Kazuki in the episode "No Disguise". He's a real doormat in that one, he shouldn't have had to take all that. Mitsuki laughing at him in his new uniform sure didn't help much. I felt sorry for him but still that's hilarious!
What do you do when you've just taken over the world? Go shopping!
In episode 6 or 7, Kazuki and Commander Sanada bond over cup noodles at midnight, exclaiming that they just have to have that cheap junk food taste and that Mitsuki would never make the stuff. Then Mitsuki walks in and forces them to eat a full meal, either left-overs or something she pulled together on the spot.
These seems to be Ken Sanada's reason for living. Be it sending the U.N. Inspector a porn audio track instead of the information she requested or simply telling her that "she looks wrinkly when she's angry", Ken seems to live to mess with the heads of not just her, but everyone around him.
