Wait, how come Kyoko and Haru don't remember Byakuran? At least in the scan I read they said "That person's flying!", wouldn't they be shocked to see Byakuran again? Or at least recognize him? I thought Tsuna revealed everything back in the future arc to the two of them. It's been a long time since then, so my memory's pretty poor.
Anyways, good chapter. I like where this arc is heading.
