-> Hiro&Takaaki's tsurime eyes -> who else notoriously has tsurime eyes? Shuukichi. -> and it turned out to come from his dad Tsutomu (while Masumi&Shuuichi got the Mary eyes) -> as of yet, we don't know anything about Tsutomu's side of the family -> in flashbacks, we haven't seen much of Hiro&Takaaki's parents (before they got murdered) -> if there is one thing you learn fast in DetCo, it's that you're always two degrees of separation or less from the Akai-Sera-Miyano -> Shuuichi Akai might always be your secret cousin, it has happened before.
I'm not saying that GA could still do the funniest joke* with yet another surprise! family. reveal, but...
#* “funniest” = anything that might make Rei Furuya explode in anger.#is nothing sacred to you akai shuuichi etc.#it's not something i actively believe (unlike. gin actually being tsutomu. which would be SO SO FUN in its horribleness.)#but every thought that you make rei's life more miserable (his BEST FRIEND having any tie with this FIEND) is welcome <3#fluffy family#dcmk#or as we call it: the akai family extended universe
