You were looking planet to planet, invisible, and saw a planet where the main source is jujutsu and sorcery with a slight evil (curses) to it

You went invisible and went on top of a building and saw people fighting. You scanned them with your God-Given Powers

You phased through still invisible and saw people staring through reinforced glass. You went visible behind them, waiting until you felt a presence behind you.

Suddenly, a curse named Rika put you into a chokehold, and Yuta looked back while Utahime looked confused at who he was looking at

Yuta> Who are you? I sense a powerful presence... But have not seen you before. Say something before you lose your life, not speaking.

Utahime and the others turn around

Yuji> Yeah! Who are you? Utahime> ...Yeah... I haven't seen you before.
