Hibiki only addresses Dita directly by name three times in the second season (Vandread: Second Stage). Once in "Red Angel" when Dita is chasing him in her pajamas about visiting her room right after their meeting about a shared dream. Then he says it twice in "Trust": when Dita is rushing in to save his Vanguard as it fights off the planet killer's self-destructive gateway; and when he's inviting Dita onto the shuttle to Taraak at the very end.
Space-alien-happy Dita uses the "alien" hand gesture from Close Encounters of the Third Kind when she meets Hibiki, (who she calls "Mr Alien") for the first time.
This is the first TV anime to use both digital ink & paint & 16:9 widescreen respectively.
