Episode 3:

WTF, that was so dumb. Blabla, honor and all, but he was offered freedom and declined to continue risking his life in every single battle. This is some serious anime-fication of ancient Rome, lol. There was no reason to stay a slave, he could have done honorable things afterwards, too. Oh boy ...

Until the last scene I kinda wanted Emden to succeed with his 50 victory streak, but that last scene made him look so spiteful that I'm ok with Cestus punching him thorughly.
