These two titles share not only some psychological themes (identity complex, definition of humanity, communication and relationships, courage/fear, self-realization/suppression etc.), but I also find the art style quite similar. I can even find some resemblance of characters, where as Key alias Tokiko Mima shares the same behavioral archetype as Rei and Sakura Kuriyagawa reminds me of Misato.
