Fun Time is officially over as shit hits the fan on all fronts in this taut, slithering, devastating, unforgiving powerhouse of an episode. It starts quiet on a rainy morning. Miki laments that she’s finished her book—at the end of which its implied the dog comes to a bad end—Rii-san informs her why she’s so down: this is the same kind of day when they lost Megu-nee, their sensei and caring protector. Ever since then, Rii-san has been trying to fill the void Megu-nee left, and the strain shows this week as pretty much everything that can go wrong, does.
Kurumi, the muscle of the group, confidently strikes out to find the escaped Taroumaru, assuring Rii-san she won’t do anything rash. She ultimately can’t abide by that assurance, first locating a zombified Taroumaru, then Megu-nee herself, in the previously un-explored basement. Why she goes alone is beyond me, but like I said, she’s a tough one, so I guess Rii-san felt she could trust her to come back safe and sound on her own.
As soon as she spots both Taroumaru and Megu-nee, Kurumi knows what she has to do; it’s just a matter of being able to do it. She was able to kill her would-be boyfriend before he killed her back when this all started, but her hesitation results in Taroumaru running rampant until she can trap him in a room (with a non-sliding door he can’t open). And when Megu-nee raises her face, Kurumi can’t help but see her memory of her warm, beautiful, heroic teacher, not the shambling monster before her.
She loses her nerve, and Megu-nee bites her. Damn, that was fast. Kurumi gets back to the safe zone, but it isn’t long before the wound starts to fester, and it becomes pretty clear that things are not going to go any better for her than they went for the dog or the teacher. It’s only a matter of time.
During this time, as she screams in her sleep, we go inside her head, where she’s trapped in a nightmare in which countless zombies stalk her from just behind the walls of a classroom she’s in.
When they break through, her mind will be lost and she’ll be one of them. The only glimmer of hope she can be saved comes when Miki consults the emergency manual, which indicates there’s medicine—an antidote?—down in the basement shelter.
Rii-san doesn’t want Miki to go alone, but she doesn’t have much choice; she has to be there if and when Kurumi turns. As for Yuki, her bubbly obliviousness is more of a liability than ever. Miki and Rii-san are going through emotional issues of their own, and they have no time to babysit her.
Miki finds Kurumi’s shovel, but also spots Taroumaru’s still-full dog bowl and collapses into tears, remembering how Kurumi lamented that she’d “failed”, and believing she too had failed to protect Taroumaru, just when they had kinda become friends last week.
Miki claims not being close to Megu-nee (who we see sitting down there, “writing”) will make it easier to take her out, but the dog’s down there too, so her task to grab the medicine—before Kurumi turns—is not going to be easy, to put it mildly.
As for Yuki, when she stops in the hall to remark to herself how today is like “that day”, and she then asks herself what “that day” is, and then feels the cold rain hitting her on the face. She sees the broken window now, just as the zombies burst through the ground floor and start bringing the barricades down.
We can imagine what she’ll see next week. The question is: how will she react to her sudden awakening? Will she be able to play a role in her own and everyone else’s survival, or are they all doomed?
