"Yusuke Godai, do you know about this? (shows him a thumbs up gesture) It's an ancient Roman sign to show satisfaction. This was the gesture given to someone who overcame any obstacles. You should be someone who aims to be worth of this sign too. Losing your father was certainly a sad thing for you... But because of that for the sakes of your mother and sister you must work hard to be a man worth this sign to be shown to. Become a man who will always protect everyone's happiness! Do you think that is truly a wonderful thing? Me, your teacher, thinks so."
―Kanzaki's words that became Godai's life motivation.[src]
