A horror series by Abubu featuring characters from Kemono Friends that takes place inside of an anomalous apartment complex. The story initially follows Common Raccoon ("Arai-san"), who is trying to get back home, but also features the adventures of a team of Giant Otters as they explore the dangers and other oddities of the building as well as a number of original characters.
The Japanese word マンション (manshon), while it is borrowed from English "mansion", rather means "large apartment" in Japan.
