The Moon Festival has come, and Hibiki is excited because her dad finally found her mother’s handmade decorations. She invites her friends to her home to decorate the tree, eat her special tamagoyaki, and write down their wishes, which she says have traditionally always come true in her family.
That’s made clear when her wish to have friends is pretty much redundant. Her other wish, written on a very old piece of paper, because it’s an old wish, is one her living friends can’t help her with…but her ghost friends believe they can: meeting her mother. It’s a perfectly normal wish for any girl who has never met her mother, yet Hibiki thinks it’s selfish. Nevertheless, RCS and Kogal travel into the spiritual plane of her mind as she sleeps to try to make it happen.
There, they find a spiritual Yuuhi, who has been watching over Hibiki her entire life through a mirror in a washitsu, and tending to a morning glory plant that is connected to Hibiki. The plant withers if Yuuhi leaves this room, which is why she’s never been able to fulfill her own wish to hold her daughter.
RCS and Kogal, along with Ero-Neko and all of Hibiki’s other ghost friends, arrive at Yuuhi’s room to take over for her temporarily so that she can see Hibiki. The scene where the mother and daughter finally meet and embrace is the most moving and powerful yet in a show that’s been full of them. Such a simple wish, fulfilled at last. As Hibiki falls asleep in her mom’s lap, her dad peeks in too, happy the two women in his life were finally able to connect.
But when Hibiki wakes up the next morning, not only is Yuuhi gone, but all the other ghosts in her life as well. It would seem that the morning glory plant represented her sixth sense, which Yuuhi had been tending all her life, and even the combined spiritual power of her friends wasn’t enough to make up for Yuuhi’s temporary absence, and the plant died.
While Hibiki has lost her sixth sense and thus all her ghostly friends, the fact remains she has a solid group of living friends. The preview for the penultimate episode hints that it will be their turn to help her get that sense back, if they can.
