The End of the 4½ Tatami Age

The protagonist, still trapped within the 4½ tatami world of the previous episode, continues searching for a way out, to little avail. After much exploration he eventually comes back to the room he started from and despairs, thinking of how fervently he wishes he'd done everything he did in the past episodes. He realizes that in every room, Akashi's lost mochiguman is still hanging from the ceiling, finally admitting to himself that he had loved Akashi. He proclaims his intent to seize this opportunity, and a swarm of white moths appear, which he moves back to avoid and in doing so ends out tripping out of the tatami world back into reality.
