Disillusioned with any form of campus life, the protagonist joins no clubs as a freshman in college, choosing instead to spend all his time within his 4.5 tatami room. He awakens after 2 years to find that he is surrounded by an infinite number of seemingly identical rooms beyond every door, window, and wall. He sustains himself on castellas he finds in the rooms, and explores, collecting bits of money. It becomes clear that the rooms are not in fact identical, but bear slight variations corresponding to the choices he could have (and has) made throughout the rest of the series.
第 11 集 The End of the 4.5 Tatami Age
播出时间：2010年7月3日
The protagonist, still trapped within the 4.5 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.
