The latest book of the final season of the best-selling MONOGATARI series. Before we witness the series’ climactic showdown in the third volume of the "End Tale"—each part of which forms its own cohesive whole—narrator Araragi wrestles with a crucial bit of history that had turned him into the loner we met at the very beginning, who opined that friendships only lowered his intensity as a human. What initiates his pilgrim’s progress of a reckoning is his first encounter, at school, with the mysterious freshman Ogi Oshino, self-described niece of the equally enigmatic aberration expert Mèmè, and the book’s opening chapter is a harrowing standalone novella of a whodunnit involving a locked room of sorts. Our increasingly well-adjusted hero kept on being decent at one thing even when he was just hanging on, but this forte, an unlikely aptitude for math, of all things, becomes the focus of a cheating scandal and a web of recollections that forces him to come to terms with, what do you know, his capacity to connect to people.

During his third year in high school, Koyomi Araragi is introduced to a transfer student named Ougi Oshino Ougi tells Koyomi that there is something odd about Naoestu High School… a secret room on thats not on the map. What will Koyomi and Ougi find in this hidden room?

When an old flame who gave up on life and chose to go up in flames—because he wanted to leave you but couldn’t—comes crawling back after four hundred years, you might not appreciate it, especially if you’re in a new relationship. But nothing’s ever simple between people, and that’s even truer between monsters. For the first time in months, our heroic loser Araragi is human, parted by previous events from the ex-legendary vampire bound to his shadow. Before he, the second-ever thrall of the former Kissshot, can resume his partnership with the donut-loving waif that she’s turned into, she must make a choice—about that first-ever. Before the End Tale can end, some loose ends must be tied, and in this volume, the fixer Gaen calls in her favor, requesting an introduction to her niece; the errand of the amulet that Araragi ran with Kanbaru comes into crisp focus; and the time-traveling and -spanning Dandy and Demon Tales see their devastating resolution.

Just when we thought the darkness menacing the town had been identified, named, and tamed, clear and unclear mysteries of seasons past looming or surfacing, then resolving, not without tears, not without bittersweetness, of course, but satisfyingly, in a tripartite finale, all loose ends tied up into, or at least with, a bow…
The End Tale continues—if only for one last time, in a bonus stage for the ages, as our softie of a protagonist who wished for all parties involved, including himself, maturely enough, to end up happy, sees his reflected image freeze in a mirror and regretfully, regrettably, reaches for it to find himself through the looking glass.
In an alternate reality where bits of the world have been flipped around, the hero comes face to face with the hidden side(s) of familiar faces, along with author NISIOISIN, whose bravura attempt to reimagine character possibilities concludes, with signature flair, the MONOGATARI series proper—thank you for reading.

Presented in two parts with covers that will form a diptych, Calendar Tale, narrated by our titular hero, sends us to various earlier points in the story where certain events had yet to occur—when, for instance, the shady “expert” Oshino was still in town, and the ex-legendary vampire Shinobu hadn’t tired of sulking in a corner. Weaving in a motif of ways, paths, roads, and streets—walks of life—the nostalgic vignettes hark back to the “case files” feel of the series-launching Monster Tale, but with a twist. Not all oddities are supernatural: stones and flowers; sand and water; the wind and the tree can just be plain weird without being aberrations. In this installment, say hello from the future to class president among class presidents Hanekawa, acid-tongued girlfriend Senjogahara, cheeky lost child Hachikuji, smutty athlete Kanbaru, pathologically shy Sengoku, and justice-loving martial artist Karen, young ladies who love to make our young man sweat.

In this latter half of Calendar Tale, a set of journeys into the past that have been revisiting the “case files” feel of the series’ origins starts to catch up to the present moment until we are violently spliced back into the overarching plot, just in time for the final quartet that is the End Tale (in three volumes) and End Tale (Cont.). Continuing with the motif of ways, paths, roads, and streets, and wrapping up sundry other topics and quasi-philosophical concerns, the vignettes for the months of October to March deal with six ladies who are either not quite human or older than titular narrator Koyomi Araragi, bless his bantering soul. In this installment, see how he handles—or is handled by—aberration of a little sister Tsukihi, enigma of a freshman or -woman Ogi, shadow of a legendary vampire Shinobu, corpse of a tween girl Ononoki, psychopath of a monster expert Kagenui, and know-it-all of a Machiavellian fixer Izuko Gaen.

The improbable imprisonment that transformed "I" into a novelist continues into a third, fourth and fifth day. "U" obsesses over formalities, as "I" quietly coaxes her into taking care of herself. As this bizarre farce of a kidnapping stretches towards the inevitable breaking point, "I" starts to discover the truth about "U", a truth he should never have learned…
