Revealing the Leader of the Black Organization: Who Are the Suspects and Who is the Real Leader?
After years of theories about the leader of the Black Organization (Ano Kata), here’s the official reveal… and how the “Put On Mascara” code led to the truth.

Unveiling the Hidden: From Agasa to Karasuma… How Was the Leader of the Black Organization Exposed?
Revealing the Leader of the Black Organization: Who Are the Suspects and Who is the Real Leader?
Since the beginning of the “Detective Conan” journey, the question that has troubled millions is: Who is the leader of the Black Organization (Ano Kata)? Over 30 years, wild theories have emerged—some quite logical, others downright shocking.
The Search for the Organization’s Boss… Who Are the Suspects and Who is the Real Leader?
Here are the most famous theories proposed by Conan fans, leading up to the official reveal:
1. The Most Popular Theory: Dr. Agasa (Hiroshi Agasa)
For many years, “Agasa” was the undisputed prime suspect.
Reason for Suspicion: He’s the closest person to Conan and creates inventions for him, making it easy to monitor him. Also, rearranging the name “Agasa” or linking it to alcoholic drinks (like the Agassa cocktail) raised doubts.
The Decisive Response: Gosho Aoyama (the author) has repeatedly and categorically denied this theory, confirming that Agasa is completely innocent.
2. Theory: Yusaku Kudo (Shinichi’s Father)
Reason for Suspicion: His superhuman intelligence that surpasses everyone, his constant travels, and his mysterious smile. Some thought the story would turn into a family conflict between father and son.
The Decisive Response: He wouldn’t shrink his own son or put him in danger, as that’s against basic paternal instincts. Also, he stands with Conan, especially after staying in Japan starting from episode 942, and helps him in his plans against the organization.
3. Theory: James Black
Reason for Suspicion: Leader in the FBI, and his name reminds us of “James Moriarty” (Sherlock Holmes’ enemy). His first appearance was very mysterious, and some believed he was the “mastermind” manipulating everyone.
The Decisive Response: James has previously planned with the FBI, especially Jodie, Akai, and Camel, in operations to take down the organization, particularly in the “Clash of Red and Black” arc. He was the one who asked Akai to lure Gin for capture while he was in the organization, but it failed due to Rum.
4. The Shocking Theory: Kogoro Mouri (Togo Mouri)
Yes, the “Sleeping Detective” himself was under suspicion.
Reason for Suspicion: Proponents of this theory believe he “pretends to be stupid” and isn’t really asleep, but plays the fool to control the crime scene and divert suspicions from himself. So why doesn’t he ask, investigate, and confirm the reason for his sedation, sleeping, and solving cases while asleep? Also, the organization avoided killing him on multiple occasions despite his proximity to their investigations.
The Decisive Response: Following his inner thoughts proves he truly knows nothing, and he’s an alcoholic, a womanizer, and loves Yoko-chan more than ruling the world! 😂
5. The Weirdest Theory of All: Genta Kojima
Believe it or not, some thought this child was the leader.
Reason for Suspicion: The theory that the leader is someone no one would suspect at all, perhaps pretending to be the dumbest, in Genta’s case. Maybe he took a shrinking drug like Conan because he was an elderly person in the past. Some analyzed his leadership behaviors in the “Detective Boys” team and considered his love for “eel rice” a secret code!
The Decisive Response: Genta is innocent, and all he cares about is food for real.
🚨 The Official Truth: Who is the Leader of the Black Organization?
In episode 942 (and chapter 1008 of the manga), the leader’s identity and real name were revealed, and it is:
🦅 Renya Karasuma 🦅
Why him? And how was he discovered?
The secret lay in the “death message” left by Koji Haneda 17 years ago.
The message consisted of remaining letters from the word (PUT ON MASCARA) after breaking the mirror.
By removing the letters (P, T, O, N) that form the word “ASACA” (the name of the suspected personal bodyguard), the remaining letters are:
U M A S C A R A
Rearranging them gives: CARASUMA.
🚨 Quick Facts About Him:
He’s a mysterious millionaire said to have died long ago (but he’s alive). His family symbol is the “crow” (Crow), which explains why organization members wear black (the color of the crow).
Only his shadow appeared in the very old “Sunset Manor” case, proving that Gosho had planned this from the beginning!
