Like... wtf? (for the fandom folks)

This made me go "buduh" when I read it, and it will make you go "buduh" too. It was an author's note at the end of a Riku/Sora fic.

"Comment to yaoiboyjj49: I can’t remember if I ever e-mailed you with an answer about this, so I’ll just repeat it here. Um no, Satoshi and Daisuke never hook up. They always stay the best of friends and have to keep the others in line. Eventually Daisuke hooks up with a girl who is kinda like a Ginny/Riku hybrid and Satoshi finds himself a wild boy who manages to bring out his more emotional half. Krad hates this boy though and has tried to kill him many times but Draco or someone usually stops him. Dark and Drey approve of Daisuke’s girlfriend though, so everything ends up happy. Oh, and on a side note, the Harada twins and Weasley twins get married and have lots kids, about three each. Daisuke as well has a little girl that he loves. But that’s in the far future."

...

What does that even mean? Is that person writing a HP/KH/DNA cross-over or what? 0_o;;
