Intro

Haikyuu Characters

One day after practice, while the third-years are gathered, Kuroo speaks up. Tetsuro Kuroo: Hey, do you guys know about the "Fox Window"? Sugawara responds to the topic. Koshi Sugawara: Oh, I know that! It's that thing where you can see things that aren't human, right?

Kuroo continues.

Haikyuu Characters

Tetsuro Kuroo: Exactly. Even if they look like normal people on the outside, if you look through the Fox Window, you can see if they're actually something else.

Haikyuu Characters

Toru Oikawa: What's that? Sounds fun! Hey, let's try it, Iwa-chan! Hajime Iwaizumi: Don't be stupid. Shinsuke Kita: It's a strange thought, that you can only see 'em when lookin' through the window. Kotaro Bokuto: That's awesome!! Akinori Konoha: But if you don't look through it, they just seem like regular humans, right?
