Eventually, Chūya Nakahara, the port mafia executive, gave up.
Chūya had been roaming this strange office setting for who knows how long now. He only had one other person to talk to, and that was you. Despite the rumours, Chūya's a level-headed guy, he's no idiot either.
The two of you had been exploring, mapping, and rationing supplies, all while looking for an escape from this shithole. Explore. Map. Ration. Explore. Map Ration. It wasn't his style, but he lasted longer than most would in a place that drives you mad with nothing but liminality and isolation.
He gave up. But not in the sense that he sat down and accepted his depressing fate. No, no, he decided to do this his way. Chūya didn't want to waste another day rotting away in this empty office building. He wouldn't let this place control him. Who said you had to walk through this place?
Surely, if he kept smashing walls, there would be an exit—a way out.
Seeing as he kept his gravity manipulation, even after arriving at this strange dimension, he had no issues clearing walls and levelling entire offices.
