Associate Professor Akira Takatsuki's Conjecture vol. 4 by Mikage Sawamura

This series has become a comfort reading of mine, and I read the latest volume in one sitting. In my defence, these light novels aren’t very long. Volume 4 has a subtitle Thus, the Gates to the Spirit Realm Open, which describes the contents fairly well.

It’s April and Naoya Fukamachi has begun the second year of his studies at the university in Tokyo where he studies folklore with Associate Professor Akira Takatsuki. They’ve spent most of the spring break travelling together, but Naoya is still slightly anxious that Akira won’t need his help anymore in investigating supernatural incidents. He shouldn’t have worried.

There are only two—long—chapters. In the first one, a popular story to frighten children surfaces at a workplace. In it, one summons a hag or a curse or enters another dimension if they perform required things on April 4th at 4:44—number four being ominous, as it’s pronounced like death. Four people at the workplace have performed the summons and bad things have started to happen to them.

It doesn’t take Akira long to unravel the mystery, which once again turns out to have a mundane origin. But the case proves important to Naoya, because he meets another person like him who can hear lies due to similar events as his. Having someone with whom to talk about it makes a great impact on him. He also makes an effort to become more sociable, even if it’s only with one friend.

In the second chapter, Akira’s uncle comes to visit, and Naoya learns a lot about Akira and his past—although the reader doesn’t find out until during the extra chapter at the end. He’s the only family member who cares about Akira, and he’s relieved to learn that there are people looking after his nephew.

Together with Ken-Ken, the four travel to a seaside town where fishermen claim to have seen mermaids. It appears to be a hoax, until they meet a little boy who tells them that his mother has become a mermaid and returned to the sea. Dismissing it as a story first, they soon learn that things might be more complicated than they believed. And for the first time, they may have encountered a being who isn’t quite human.

In the extra story, we learn about Akira’s youth in England with his uncle. It’s a slightly sad story, revealing sides of Akira the reader hasn’t known before, but hopeful too, as Akira heals from his trauma with the help of his uncle and his found family. We still don’t learn more about the being inside Akira, or what happened to him when he was abducted, but it’s becoming certain that the mystery is supernatural in origin. I’m eager to read more.
