Author Aoyama Gosho revealed in the Shonen Sunday magazine released on November 30, 2017 that Karasuma Renya is the man who heads the mysterious Black Organization. So what kind of person is Karasuma Renya?
The Identity of Karasuma Renya
Karasuma Renya was an extremely powerful and wealthy man. In his lifetime, he collected over three hundred priceless ancient works of art and inherited the Sunset Castle from his mother. He was always searching for treasure in the castle he inherited. He hired archaeologist Kyosuke Senma and several experts to solve the riddle of the treasure but got no results. In the end, he killed them to motivate others to work more efficiently.

However, he was later said to have died mysteriously and his legacy disappeared without a trace. The Karasuma clan soon fell into disrepair after his death and the mansion fell into the hands of others. However, the objects in the mansion have remained the same since then, and countless old blood stains can still be seen in the mansion.
The owner of Karasuma Group
Karasuma Renya founded the Karasuma Group, an organization that generously funds many activities. However, there are many bad rumors about this Group. He is the one who funds the research of Atsushi and Elena Miyano - Haibara's parents.
