I'm writing a fictional immortality script in Detective Conan.

(Conan, the male protagonist who enjoys himself, no romantic pairing, a crossover of the Elixir of Immortality setting, Black Faction, some personal modifications, and a side connection to the culprit, Mr. Hanzawa) Kuromon Haruya, a Conan fan of the Black Organization. After unfortunately being transported to a fantastical murder scene and drinking the Elixir of Immortality, he decides to establish a branch of the elixir factory to replace his meals in order to pass the time. Under his deliberately laissez-faire management, the organization grows stronger (and more unreliable), becoming increasingly similar to the original Black Organization. He adopts a child named Kurosawa Jin, trains a female celebrity whose stage name is Sharon Vineyard, and even coincidentally hires a family of three with the same name as the Miyano family... etc., completely identical names...
