(Uno to Hajime) "He's a stick in the mud and has the worst handwriting. He's not good at math and can't play any sports. He's clueless when it comes to recreational activities. He can't do anything besides escape from prison the idiot. But.. He understands us... More than anyone else. He understands people. If you believe only a monster...Then I think the one.. Who's the real monster."

(To Jyugo) "You're such a gloomy Gus, aren't you? You're so gloomy, indecisive, and so pessimistic. You're also dull, have bad handwriting, can't learn, insensitive, weak, a slow runner, a poor talker, and a poor liar. You really can't do anything other than break out of jail. Also you have short legs. But... that means you have lots of character traits, right? That's all you need to know for now, don't you think? If you don't know something, we'll teach you. We're gonna make your life more fun. It doesn't matter whether we're in jail or Hell. If we live happily, we win. So let's take it slow and make sure you'll enjoy tomorrow."
