How did Conan, a famous detective, know Akai Shuuichi and Miyano Akemi, and in which episode was it told?

TV497 "The Collision between Red and Black Awakens"

Driving after Kusuda Rikumichi, a member of a black organization, he knew his opponent was Hideyoshi and committed suicide. The relationship between Miyano Akemi and Hideyoshi is fully introduced, and Hideyoshi's classic posture also appears in this episode. Don't miss it for Hideyoshi's fans!

Akai Shuuichi used to have long hair like gin. Two years before Shinichi became Conan, he sneaked into the dark organization under the pseudonym of "Zhuxingda". During this period, he kept in touch with Miyano Akemi (Hirota Yami), a member of the organization (it can be seen from the cartoon that this connection is suspected for a certain purpose), and had a relationship with Miyano Shiho (Haiyuan Ai), the sister of the organization scientist (file 599, solo book V58, file 2 Akai Shuuichi's past). Akai Shuuichi achieved a high position in the organization on his own, and got the organization code of "rye (rye whisky)", which is second only to gin. He will be able to meet the boss of the organization. Akai Shuuichi's identity was exposed due to the mistake of an FBI agent Andre Kammeyer, and he finally managed to escape from the organization and return to the United States. In the United States, he also investigated the murder case of new york wearing absinthe (TV288 Kudo Shinichi new york incident (solved)). Because Akai Shuuichi's ability is so strong, he is regarded by the organization as a "silver bullet" that can threaten the life and death of the organization.

Minmei has been trying to leave the organization and reunite with Hideyoshi since she fled. Before a mission, Minmei sent a short message to Yixiu: Jun, can you really associate with me as a boyfriend after you leave the organization? It's a pity that Minmei was finally silenced by juniper in that incident (TV 128 black organization 1 100 million yuan robbery). Akai Shuuichi cut off her long hair in retaliation for her "lover" Kim, and soon came to Japan to continue investigating the case of the organization.
