Security Capsule

Company man Heiichi Uranari (from episode 2) feels more comfortable living in his old car than staying at home, but the car breaks down so Moguro takes him to a capsule hotel. Uranari sleeps badly because of hearing others snoring, so Moguro takes him to another hotel with security capsules that seals out the outside world. Uranari sleeps so well, that when he emerges he finds a post-apocalyptic world where he is the only survivor.
