## Description
In the secluded mountains of the Tohoku region lies a village named Nanatsuki. 
Drawn by tales of a peculiar local legend, two curious students from a Tokyo university decide to investigate. 

Their journey, however, takes an unexpected turn when a blizzard engulfs them. Fortunately, they're rescued by Benio, the second daughter of the influential Nanatsuki family, who welcomes them to their imposing black mansion, Shichitsuki-kan (The Mansion of Seven Possessions).

As the students settle in, they discover that the Nanatsuki family is amid an unusual wedding ritual. The bride must spend a night inside a coffin, and the marriage is deemed official if dawn arrives without incident. But as the ceremony progresses, it's abruptly disrupted by an ominous force, casting shadows of doubt and suspicion on everyone present, including the ten attendees and the two outsiders.

As dawn breaks on this isolated island with no escape route, the aftermath of a grim tragedy unfolds.

## Characters
### Kobayashi Satoshi (古林 智士)
Satoshi is a college student from a Tokyo university, specifically part of the Folklore Research Seminar. As a junior to Souko, he finds solace in his hobbies, which include delving into books and taking strolls through the city. He also has a particular fondness for Chinese Ramen, especially Chuka Soba.

Despite being in the academic setting, Satoshi often remains in the shadows, not drawing much attention to himself. He might not be the sharpest in his class, but he possesses a unique perspective and proves himself to be quite observant. Time and again, he acts as a pillar of support for the reserved Souko, assisting her as she navigates various social situations. 

There's something about Satoshi's youthful appearance and his calm demeanor that seems to captivate those older than him, often evoking a protective or even parental instinct.

"I feel this way... because I want to keep you safe."

"That's an intriguing deduction. But from an outsider's perspective like ours, it seems the root of the problem lies within the family's internal conflicts."

Therefore she has never seen the outside world and doesn’t know quite a lot of things we consider common sense. Somewhat shy and softspoken. Loves singing.
