I always thought Daisuke made a cute main character. And welcome to Uzumaki Naruto! More members = more fun! ^o^
As for KyokoButterfly's question, I thought at the beginning that Daisuke would probably win over Risa somehow, even though I've never liked her very much. Now that I know he ends up with Riku, I feel happier because it seems like Riku is a lot better for Dai.
RegICE, I didn't exactly find his dad turning into Argentine, but there was that conversation between Dai and his Grandpa about Satoshi's family. It's very peculiar that no fathers/grandfathers are mentioned. By the way, I thought you meant Argentine being like, his biological father?
By the way, this is the longest running DNA fanclub ever. The rest died after like two pages.
