Gekkou

Sakamoto is a seemingly ordinary young man who works at a help desk from 9:00 to 5:00. His lives in a single-family house in a quiet suburb. There, in the basement, which is locked up tight, he lives in a communal arrangement with a girl who has some strange reason to be there. Unusual keywords like "Shoto Family Murders," "Dark Site," "Kidnapping," and "Written Dialogue" - what do they mean? Newcomer Yuji Uchiyama, who has been active at Comitia, depicts a "daily life crime suspense" story with a touch that is entirely unique.
