Augustus Sinclair

"Augustus Sinclair. A guy who lives in Rapture, is such a rich guy. I don't understand if this guy wanted to spend time to research for more stuff that he needs, and especially, money. So much money. See, if you think charity is you, then I won't fall for another greedy drivel again. But now I must warn you, this man is as greed as he should. It won't be nice if I know that, huh?"

--Su Ji-Hoon, Sinclair's Fate
