Adam and Eve are known as the first humans created by god which makes sense because eve is the first esper. Isaiah is a prophet of judgement, which shows in the latest chapter where he tells Gabriel to send the message to humanity. Which prob means some damning judgement. Gabriel is known for announcing the birth of Jesus. Which shows in how he was the one to send the message to humanity. We will prob see a lot more references throughout the story.
Names Adam, eve, Gabriel, Isaiah is a good indicator for what role the character plays in the story. This cliffhanger is crazy - is there going to be another crisis where humanity needs Espers again? What message is Isaiah going to convey next chapter? As he is know for being a prophet who gives terrifying judgement warnings
