She is a young-looking woman who wears clothes that are too large for her. Izuko often boasts about her knowledge, coming off as somewhat arrogant. She claims to know everything, to the degree where she can predict the future; as a result, she likes to brag about this with her catchphrase, "There is nothing I don't know, I know everything." Izuko is also the younger sister of Tooe Gaen.
When others get help from her, she wishes for something in return; usually ending up with them doing her a favour. ~!She was the senpai of Oshino, Kaiki and Yozuru in their university years.!~
~!It is implied that, while creating Yotsugi, Izuko was cursed with knowledge.!~

A tale of heroine Tsubasa Hanekawa from her own perspective, in her own voice—if that can hold true for a damaged soul who, depending on who you’re asking, suffers from a split personality or a supernatural aberration. The bone-chilling brokenness of her household, where father and mother and daughter keep three separate sets of cookware in the same kitchen and only ever prepare their own meals, and the profound darkness nurtured in the genius schoolgirl’s heart, come to life, if that is the word, through her self-vivisection.

It, like the dark that makes up most of the cosmos, is not an aberration. Nonbeing can swallow you whole, yet if anything, it’s the anti-aberration. Darkness, in fact, is the Law, an executioner from whom a mark can try to run and hide, but only for so long. When it comes calling, the fortunate just might have the time to say goodbye. And the Darkness is—here now. Before ever visiting Japan to find a place to die, four centuries, indeed, before her failed suicide attempt, the legendary vampire KissShot literally stepped foot on the land of the rising sun with an epic jump that ended a lonely sojourn in Antarctica. It was back in those days that the proud noble created her first thrall. It was then, too, that she first met the Darkness.

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. After revisiting with a “case files” feel of the series’ origins, we will start to catch up to the present moment until we are violently spliced back into the overarching plot.
 
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. 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 instalment, 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. See how he handles—or is handled by—aberration of a little sister Tsukihi, enigma of a freshman or -woman Ougi, 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.

Note: The English release was split across two volumes, instead of the original singular volume.

Volume 1: 
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 who-dunit involving a locked room of sorts.
 
Our increasingly well-adjusted hero kept on beingdecent 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.
 
Volume 2: 
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.
 
Volume 3: 
No good deed goes unpunished, they say, and so does friendship and lowering your intensity as a human, they don’t say—alas, for all his literally painful hustle and inveterate need to save others, our brave fool of a hero ends up in hell, a conception of the inferno in its full Buddhist glory, and muses (lol) if there’s a return ticket.
 
Told in three chapters, the final part of End Tale concludes the story proper and resolves the series’ panoply of ongoing mysteries: the dues of a do-gooder for relying on a power not his own, the identity of a shady transfer student, the outcome of a class president’s questing abroad, and even the true name of a park.
 
Araragi, indeed, is the one who knows, but along the way he meets old faces, really every last one of them, who aid him on his journey for understanding, and perhaps for salvation, and you for one might not be surprised if he had another rendezvous with an erstwhile “cloistered princess” before it—guess what it is—sees an end.
