Kagami literally says "I want to *** with Konata!" in the OVA, but, yes, let's all just sit here pretending it's not canon despite the word of god even though you won't use the same standards for couples like NanoFate. In the meantime I guess YumiKuri, PapiCoco, and FinexIzetta are not canon either by the same standard.
@Vankomycin The author is Yoshimizu Kagami, the guy that drew this very picture. Which makes it much more significant than the other official
wedding art of the two.
