The BS Situation of Tougetsu Umidori

It’s a day just like any other for Tougetsu Umidori when out of the blue, her classmate Nara Yoshino makes a strange request: Help her catch the thief who’s been stealing—her pencils…? But there’s more to this eccentric little request than meets the eye, especially when a weirdo in a cat hoodie who calls herself “Bullshit-chan” shows up at Umidori’s house. Who is this girl? Why does she know so much about Umidori? Does she have something to do with the pencil thief? What the heck does she mean when she says, “Let’s kill lies!”? …And why is she holding a knife?!

How did taking on a simple request to catch a pencil thief unravel a web of deceit…and a treacherous plot that could potentially end humanity?! What’s more, Bullshit-chan is attacked by a mysterious assailant, leaving Umidori in a bind. Sure, Bullshit-chan might have exposed Umidori’s deepest secret and possibly ruined her friendship with Nara—all while spewing some nonsense about “lies being alive”—but should Umidori really lend this weirdo a hand, or is it better if she leaves her to die…?
