What is Kumitantei: Old-School Slaughter about?

Himari Sanada is an ordinary girl who's had the greatest Imperial honor for students thrust upon her: an Absolute title and admission to the prestigious military research academy Janus Institute. The morning of her first day however, she does not wake up in her bedroom, instead finding herself trapped alongside 15 other Absolute students within a decaying old bunker seemingly built by their new school. Confronted by a strange two-faced cat, the class learns they've been brought here as test subjects in a kill-or-be-killed Apathy Experiment designed to fracture and drain their very humanity. Himari, the Absolute Barista, desires to overcome the eccentricities of her fellow participants and make friends, but is often instead forced to investigate and solve their grisly murders. Bond with the others to learn their Skills, scour diverse crime scenes for Evidence, and then leverage it all in the stylish and frantic Clinical Trial. Will they band together to uncover secrets of the past, or lose their humanity and lives in the present?

Should I stream Kumitantei: Old-School Slaughter on Twitch?

0/100 · Closed off· 6 viewers per streamer on paper

Probably not. The only English stream here holds all 6 English viewers — once you take it out there is nothing left to reach.

The only English stream here holds all 6 English viewers. There is nothing left over for a second.

Almost nobody here is available to you — either a couple of streams hold the room, or nobody is watching in English, or the category is empty, or you would be buried.

This reads the room as it is right now — how much of the English-speaking audience is reachable and where you would land — not how many followers you would gain. That depends on you.

Where to buy

All plain links straight to the official stores. Some will become affiliate links later, and they’ll be marked with a ♥ when they are — you’ll always be able to tell, and the unmarked ones will always be there.

Is Kumitantei: Old-School Slaughter too saturated on Twitch?

Not crowded, but not open either. Only 1 person is streaming Kumitantei: Old-School Slaughter, and the one English stream holds all 6 English viewers — so the room is quiet because that audience is already committed, not because it is waiting for you.
