Beyond the cell gate he can spot the entrance blocked by a boulder. While looking around, the figure of Security Guard Joe approaches, and tells him that this place belongs to very powerful people, but instead of listening, Date has Aiba run her simulations, which agitates Joe and makes him taunt that this place is a secret smuggling ring and shows Date a copy of the goods no one has access to. Aiba concentrates Date's vision on the guard's hand, identifying a limited edition porno mag, and he grabs him through the cell bars, forcefully hitting him trying to get him to drop the mag. The vibrations cause the boulder's support to break loose, and start rolling towards the cell. Unable to free himself, the guard desperately slides the cell gate to the side, laughing that it was gonna crush his friend, but Chris' instincts flare up and, getting up with a scream, he destroys the boulder in one swift strike, all the while still being asleep.

Date wonders why Kyle is still with TFR when he must've gotten an offer by now, but Kyle still has obligations to TFR, and to not worry since he's just fine. Date tries to pursue further, but Aiba remembers this isn't an investigation and he eases up. Kiryu then enters the bar, whom Date hasn't seen in a while, but seems like he's been dragged to this city again by now; Kiryu knows some people involved in the company but hasn't checked it out yet, and asks Date if things are as well there as people seem to say, with Date agreeing it is save from a few issues arising from the company being so new. With TFR being in such bad shape, Date and Kiryu wonder if it can ever recover from the reveal of the schemes management were plotting, but at least they shut them down. After silently observing the conversation for a while, Kyle is done with his drink, so he gets up and leaves, apologizing for not continuing with the conversation.
