The BS Situation of Tougetsu Umidori, Vol. 2 (manga)

It started with a request—how did it end up like this?!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…?
