WMG theories for The Child of Love
Rei did not hook up with Takuma
That OC shows up in the sequel and has a crush on Rei? In stories written by Axel and set in the future he is never mentioned. His name is never brought up by anybody. Rei never talks about him. Either he died during the Angel War or Rei did not love him back and he left after the last battle.Teri and Aki Ikari have met in some side of The Multiverse
Probably in Avalon, since its ruler is such a fanboy of their parents. And they got along wonderfully.
