After a pleasant dream with Reika, Date awakens to the coldness of reality after incessant nagging from Aiba, and finds himself in an underground prison cell along with a still sleeping Chris Redfield. 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 can now get his so desired mag, when he notices a skeleton on the next cell and becomes aroused; Aiba restrains herself not to shock him and ups his dosage a bunch.
