In the first two episodes, Sakura Megumi or “Megu-nee” was treated at turns like an apparently deceased teacher/semi-comic relief whom only Yuki, in her delusional state, can still see, hear, and interact with, and whom the other girls play along with so as not to further disturb their already disturbed friend. This episode goes deeper into who Megu-nee is, or rather who she was, by taking us back to the day Everything Went South.
Like the first two episodes, this third one expertly juggles normalcy with abnormality, with dread lurking just out of sight or in the far corner of the frame, at least early on. A perfect example: Megu-nee noticing an abnormal number of sirens while on her normal drive to school in her cute Mini Cooper.
The normal day proceeds, with Megu-nee getting warned by the vice principal to maintain an appropriate emotional distance from her students. That morning, Megu-nee’s Mom expressed a similar worry with her daughter’s ability to “cut it” as a new teacher.
Yet when, say, Kurumi comes to her and is able to talk about her dilemma with the boy she likes, Megu-nee proves she actually is cut out to be a teacher, in that she’s a trustworthy, approachable nurturer of minds and an open ear or shoulder to cry on.
At the same time, she’s willing, nay, determined to go the extra mile for students in need of extra help like Yuki. It’s confirmed she was never a great student and had problems focusing.
Interestingly, it’s Yuki who suggests she and Megu-nee head up to the rooftop to try to finagle some tomatoes from the gardening club member, namely Wakasa Yuuri, whom Yuki meets for the first time. This action essentially saves both Yuki and Megu-nee, because it isn’t long before everything goes to hell both in the school below them and the city beyond. The vista of just-out-of-focus students feeding off one another as buildings burn is another one of GnG!’s awesomely chilling images.
Megu-nee takes a chance on opening the door to let Kurumi on the roof, with her beloved senpai in tow. This scene gives us the whole picture of how she came to kill him with a shovel, and we see that Yuki witnessed the whole thing and in fact grabbed Kurumi to stop her from whaling on an already-dead body. Yuki’s fear and disgust at watching a fellow human being in full-on, vicious Survival Mode, is another likely contributing factor to her eventual mental break.
I like the fact that Megu-nee isn’t just an invented figment of Yuki’s imagination; she was a real person who, for a time, at least, did what she thought was her duty as a teacher, doing everything she could to protect the remaining students under her care at the school, even in a Zombiepocalypse. But while much of this episode is told from her perspective (with a grainy-film framing device), the fact remains, in the present, she is no longer alive, and exists only in Yuki’s head.
Even so, Kurumi, Yuuri, and even Miki let Yuki keep believing she’s still around, and I think it’s more than just humoring their troubled friend (and let’s face it, in a world like this, they’re all troubled). I also believe they take some comfort in the idea of Megu-nee still around protecting them. Hell, five’s better than four.
