Associate Professor Akira Takatsuki's Conjecture vol. 5 by Mikage Sawamura

In this volume, we finally get to what we’ve been waiting for: Naoya returns to the village where he accidentally entered the festival of the dead and gained (or was cursed with) the ability to hear lies. It doesn’t go well.

It’s the summer break of Naoya’s second year at the Tokyo university. He has no plans, as he’s estranged from his family and doesn’t really have any friends that he’s aware of having. When Professor Takatsuki invites him to participate in the night of one hundred horrors arranged at the university premises, he agrees, even if he’s not particularly interested.

The event is held at night in candle light. Every participant tells a ghost story until a hundred of them has been told. At the end, something supernatural is supposed to happen—and it does. But to Naoya’s surprise, Professor Takatsuki isn’t showing his typical enthusiasm for the event, which has to mean it’s fake. The mystery part of the first story is about finding out who and why, which is easily solved and isn’t terribly exciting.

Then it’s time for Naoya, Takatsuki, and KenKen to travel to Nagano and the small village there where Naoya’s grandmother used to live. He is warned against going by his new acquaintance who has also attended the same festival and gained the ability to hear lies, and by Miss Sae, the mystery woman who may be a mermaid. But Naoya needs to find out the truth.

The villagers try to keep them away too, but no one tells them why. No one wants to talk about the festival either. But Professor Takatsuki is determined to learn everything. They join a similar festival at a village nearby, and on their way back at night, they finally find what they’re looking for. Everything seems mundane at first, until Naoya stumbles into the real festival of the dead, held in the realm of the dead, and accidentally pulls Takatsuki with him.

There they finally learn why everyone wants to keep them away. The mountain god collects the people who return to the festival and keeps them forever. And this time, the price for being let out is steeper than it was when Naoya was a child.

This was a good volume. The first part wasn’t terribly spooky, despite the topic, as the ghost stories weren’t recited to the reader, and it’s mostly about Naoya observing people. The second part was great. We meet Naoya’s cousin who tells stories about his childhood, and in the realm of the dead, Naoya goes over his life in flashes, and we learn that he was very unhappy and lonely as a child. It almost makes him give up, but he also remembers the good things and friends he’s made at the university, which gives him strength to fight free.

But he’s not the only one remembering his past. Takatsuki does too. He finally remembers parts of what happened to him when he was abducted. But in a cruel twist and an annoying cliffhanger, before he can tell what it was, the entity inside him makes him forget everything—including the adventure in the realm of the dead they just had. I hope he’ll get his memory back in the next volume. It would be too upsetting if he forgets the first real supernatural event he’s witnessed. I’ll definitely read on.

In the extra story, one of Takatsuki’s graduate students reflects on the professor and why she’s not in love with him even though all her girlfriends assume she must be. It’s a nice addition to the character profiles so far.
