Fake fic title: Deku's new toy
It’s a grotesque thing, sitting on Deku’s desk and staring at him as if to mock him. Katsuki had protested its existence but Deku is a stubborn little shit and so the nine inch doll of Katsuki sits in their office, on Deku’s damn desk, offering stupid encouragements in a voice too cheerful to be his own but good enough to please the nerd.
To make matters worse, the stupid thing starts screaming and making little sparks in its upheld hands every time someone curses. It’s a disaster and Katsuki will kill Hatsume Mei for making it and Deku for commissioning it.
But first he’s got to wait for Deku to be off guard and then he will smash it to pieces. The last few tries may have failed thanks to Deku but Katsuki will see it destroyed, no matter what.
