Ice Cream Love

I'm not sure about Riku-chan's hair color...
But when I see in the Gravitation unofficial site, he has blond hair just like his ' papa '.
I really love this trio!
Well, I know... Eiri is so OOC...
I always call him 'Eiri'... Because, Yuki is his pen name as an author... (and his sensei's name or Riku's dad of course)...
