I actually wanted Adam to win, I really liked his character. Still very impressive from him to almost beat the strongest God.
He definitely underestimated Sasaki, he never cared about him and just thought he isn't worth his time. But Sasaki proved him wrong and defeated him. Poseidon got what he deserved. Sasaki is also one of my favorite characters, I really liked his backstory and the fact that he was the first human to defeat a god, especially someone like Poseidon, is just insane.
