What?! Is that true?And the 11th and 12th episodes' being delayed is all Miki Sayaka's fault...
It's a reference to a Kamen Rider 555 meme:
「乾巧って奴の仕業なんだ」「なんだって!それは本当かい?」
("It is All Inui Takumi's Plot." "What?! Is That True?")
In Episode 30 of Kamen Rider 555, Kusaka Masato tricked Kiba Yuuji into feeling a sense of distrust against Inui Takumi. This meme is a summarized version of their conversation.
