Brainwashing Detective Hisui

An inside joke. It became popular after the release of the Half-moon edition.
In that version of the game, Hisui had an odd habit of saying mind-reeling phrases like “I’ll accompany your room.” No matter how you look at it, she was definitely trying to brainwash poor Shiki.
Even the art director got in on it, and posted a picture of Hisui trying to brainwash Ciel on the Tsukihime BBS, which was cuter than you might expect.
By the way, the ad copy that the art director made up without the scenario director’s knowledge is as follows:
An inverted mystery from the mad clown of words, Nasu Kinoko!
No matter how difficult the case, it will be resolved. The catch phrase is…
“You are the culprit.”
