They're referring to Tokisaki Kurumi's yandere reveal scene in her school uniform, before she turned permanently into full-on crazy gothiloli Kurumi. That said, Kako's original K2 inspiration is probably Touhou's Shameimaru Aya. Ugume primarily draws Touhou characters and Kako K2 looks similar to how Ugume draws Aya, albeit far more energetic.
