Koyomi finds himself face-to-face with Kanbaru’s late mother Gaen Tooe in all her glory, but unlike Princess Kiss-Shot, being in her presence too long doesn’t make him suicidal. It’s a rare thing indeed for Koyomi to converse in such an intimate setting with an adult woman—again, Shinobu excluded—a cougar, if you will, made more strange by the fact she’s not even alive on Koyomi’s side.
Her frisky teasing and facial features remind him of Kanbaru, but there’s a decided sharp edge to her, quite becoming of a mother who left a monkey’s paw to her daughter—which was really a part of herself she split off. I like her leitmotif, which includes a cello, like her contemporary, Kaiki Deishu.
Tooe’s first piece of advice to a very nervous and confused Koyomi trying to figure out what’s going on is this: “knowing and not knowing don’t matter.” As proof, she infers just about everything about Koyomi’s situation and the state of his world, even though she entered the bath knowing nothing.
Tooe also underscores the necessity of properly facing your other side, as she and Izuko did, and as Suruga will have to do one day (referencing Hanamonogatari, which chronologically takes place a month after Zoku). Face it and acknowledge it not as a rival or blood enemy, but a partner, be it light or dark.
She also tells Koyomi to tell Suruga when he sees her next that her mother told her “don’t be like me.” She then mysteriously vanishes, leaving nothing but scratch marks on Koyomi’s back reading “Naoetsu High.”
When Dr. Ononoki inspects Koyomi’s back when they meet back up, the marks are gone, but Koyomi still thinks his old high school should be his next destination. Ononoki decides they’ll split up; she’ll visit Shinobu again to see if she’ll say anything else she might’ve wanted to say to Koyomi but couldn’t due tot he time limit.
Then she’ll search for Black Hanekawa to try to learn why she saved Koyomi from the Rainy Devil. Both tasks are designed specifically so she can avoid accompanying Koyomi to Naoetsu High, suggesting that while Koyomi’s influence has changed her personality and viewpoint, there’s still an innate part of her that is of this world, which understands Koyomi ultimately has to figure this out on his own.
To blend in at Naoetsu, Koyomi heads home to change into his uniform, only to discover it’s a girl’s uniform. One that, when he puts it on, actually fits pretty well. It would seem, then, that Koyomi’s theory about his other side in this world being Ougi was correct; for one thing, Ougi’s uniform is very baggy, as if it was meant for someone with a larger build—like Koyomi.
As he cross dresses without hesitation and rides his bike to school once more, Koyomi is extrmely cognizant of the fact that while he may have influenced a bit here and there in this world, it’s already starting to influence him, changing him into Ougi, which would mean Araragi Koyomi as we know him would cease to exist.
Meanwhile, after a fruitless visit to Shinobu’s, Ononoki finds Hanekawa hanging out with Mayoi and Kuchinawa…only it’s not Black Hanekawa, it’s Mini Hanekawa. Mayoi explains Hanekawa has many other sides, including her younger self. They’re all toasting the approaching end of this story, wherein this entire alternate world is revealed as nothing but the “product of a grand misunderstanding.”
That end is imminent because Koyomi is drawing closer and closer to noticing and facing his other side, Oshino Ougi. Strolling down the corridors of his old school, it doesn’t take him long to figure out, as Tooe thought he would, which part of that school meant the most to him – the classroom isolated from time and space.
It’s here where he finds Ougi, who has been waiting a very long time for him to show up. If that first episode of Owarimonogatari was the beginning of the end, and Koyomi saving Ougi at the end of Ougi Dark the end of the end, we’ve finally reached the beginning of the end of the epilogue, where no doubt Koyomi will suss out why this world exists, why he’s here, and how to return home—where he may be between titles, but at least the Karens are tall and the Surugas aren’t homicidal.
