- This Craft Essence features Zhuge Liang (Lord El-Melloi II).
- "Whydunit" is Lord El-Melloi II's favourite catchphrase in Lord El-Melloi II Case Files. It is a mystery novel term that means he focuses on the motive of why a mystery was done, instead of "whodunit" (who was the culprit) or "howdunit" (how was the crime committed).
