It looks like the Professor has a pretty standard Magneto-style goal of wiping out the humans on Earth to create a new world exclusively for espers. I assume he has some sort of vengeful reason for this revolving around past trauma as they always do. Here’s hoping there’s more to him as a villain.
It’s still got me curious what will end up happening to Kyoutarou before the final battle given that he isn’t shown in the first episode, but seems to be the main focus for the story with his connection to the main antagonists. Also, the focus on Minami in the ending theme makes me wonder if I should be expecting her to betray the Professor in the end despite her assertion this week that she helps him out of her own free will.
