So is it possible for Shido to be Mio ? I mean..Rio it's Rinne's spawn and I read somewhere that there is a moment of Shido's life after some years where Rinne is pregnant and she gives birth to Rio. I mean...Mio doesn't sound pretty bad for a man, we have Milo in real life, I can't explain the 30 years drought, but I keep finding this connection. Kill me if I am wrong but Rinne + Mio = Rio ? ...hmm...
