mm-hmm

as for the whole "Kiyo's adoptive brother" thing. Kiyo actually comes from the fallen Kirisaki clan. having been seperated by his dead (or so we think) parents the day he was born. he was found by his adoptive father Souichiro Kamiya. that's where he grew up with Rei, who was already a year old then.

this also explains where he got his "Eyes of Future Death": they were a trait exclusive to the Kirisaki clan.
