Tadatsuru Teori was a dollmaster and another Oddity specialist. Similar to Yozuru Kagenui, he specialized in immortal oddities. In particular, he specialized in dead oddities rather than living ones like Kagenui. As a stray specialist, Tadatsuru was obsessed with oddities and viewed them as beautiful creatures and even sometimes captured them for himself.

Tadatsuru was also involved in Izuko Gaen's group in college that included Meme Oshino, Yozuru Kagenui, and Deishuu Kaiki known as the Occult Research Club. Due to their different interests in oddities, Tadatsuru and Kagenui didn't get along well. After the group created Yotsugi Ononoki and she chose Kagenui over him as her master, they've been rivals ever since.

Third and “Final Season” of the Monogatari Series, part 4/5. Contains the arcs Mayoi Hell, Hitagi Rendezvous, and Ougi Dark from the Owarimonogatari light novels.

Koyasu is the most prolific voice actor in the industry, having been credited for over 700 roles as of April 2022.

Growing up, Koyasu skipped out on going to school to watch movies at home because he wanted to become an actor. It wasn’t until later that he became interested in voice acting after having seen [Galaxy Express 999](https://anilist.co/anime/1491/). After graduation he entered a voice acting school. In 1988, he made his voice acting debut, and got his first regular role a year later voicing [Gai](https://anilist.co/character/13374/) in [Tenkuu Senki Shurato](https://anilist.co/anime/2113/).

Though having voiced more characters in the medium than anyone else, he is probably most known for his role as [Dio Brando](https://anilist.co/character/4004/) in [JoJo’s Bizarre Adventure](https://anilist.co/anime/14719/). He has stated that he likes playing villainous characters.

Third season of the Monogatari Series, part 1/5. Contains the arc Yotsugi Doll from the Tsukimonogatari light novel.
 
One day in February, Koyomi Araragi was taking a bath with his younger sister Tsukihi amidst finishing his studies for the college entrance exam. This was also following the incident involving Nadeko Sengoku, which was successfully amended behind the scenes by Deishu Kaiki. Koyomi noticed a change on his body “that could not be overlooked” and sought advice from Shinobu Oshino leading him to contact Yozuru Kagenui and Yotsugi Ononoki. Was this change signifying retribution for everything that Koyomi has done?!

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.

Launching the third or “Final Season” of the international cult-hit series, Possession Tale returns the narrator’s headset back to high school senior and amateur savior Koyomi Araragi, who used to eschew friendship once upon a time because it’d lower his “intensity as a human”—a loner’s misgiving that was perhaps on the mark in a different way than he intended.
 
At issue now is not the precarious fate of one of his cherished confrères, or rather consœurs, whom he’d aid, sight unseen, with a monster’s resilience, but his own aberrant state and its prolonged abuse. If everything comes with a bill, and if no man is an island, then is the price of self-sacrificing amity—and the bloodshed it ironically occasions—becoming inhuman for good?
 
That being said! Our hero, whose first name means “calendar” but who has none in his room, sees no need to rush, so, on our way to the profound mysteries of the superhuman aspect, expect a super-shallow deconstruction of the alarm clock. On hand this volume to (hardly ever) humor his humor: his little sisters, a living doll of a corpse, and its violent mistress.
