The Phantom Thief of Hearts in Detective Conan

I hope the protagonist doesn't recruit anyone into the Phantom Thieves. If he does, I hope it's Morgana from the original work. There's no need to deliberately develop Morgana's interpersonal relationships; the main thing is that he can cooperate well as a pet cat in everyday life.

My assessment is that it's not just good-looking. Regarding the female lead, is it a no-female-lead or single-female-lead story? (Let's forget about Detective Conan harem fanfiction; there aren't many of those.) If I had to choose the female lead, I would definitely vote for Ai Haibara. But I guess many people are tired of seeing Ai Haibara and don't want her as the female lead.

The bonds of people are true power! Stop focusing on that demon fight, let's have some co-op.

Single female lead or no female lead at all, please no harem! The last Conan fanfic with the half-lover dynamic didn't work; please don't go for that in this one.

Why is everyone focusing on adding a romance plot? I don't recommend new authors add romance plots right away, because most don't handle it well. Adding a female lead will be a disaster if it's not well-written. Didn't you see how the plot of "Snake Spirit" started to go awry after a female lead was added? I think it's fine as it is now. The author has their own ideas. It's only a few chapters in, and there aren't many plot points yet, so there's plenty of time to develop it slowly.

Author, you need to figure out if you want to write a P5 fanfic set in the Conan universe, or a Conan fanfic disguised as Ren Amamiya. If the focus is on Persona 5, then bonds, friendships, teams, and the core concept of "rebellion" are definitely essential. But I really didn't see any of these elements in your update.

The name is appealing to readers, and P5 fans might stay because of the content, but it's unlikely that non-P5 readers will stay. However, I still feel it's a bit of a bait and switch, because it seems to only borrow the skin of Conan. There are no dungeons, no guns, no partners, no co-ops, and none of the content I most wanted to see in Conan, such as the battle of wits between the phantom thief and the police (just kidding). Overall, the writing is weak and the plot is not engaging enough.

After watching Moonshadow Island, the protagonist's charisma plummeted, like he went from a master con artist to a novice superhero. Couldn't they have made the protagonist a fully-fledged Joker? The fun of Detective Conan lies in the plot interactions and the involvement of Persona 5 abilities, not in having the protagonist level up by defeating monsters step by step.

The beginning part is pretty good, at least better than that other Detective Conan book, "Phantom Thief Kids."

I've seen all sorts of discussions about the female lead, isn't Koizumi Akako great? She's just as extraordinary, and it's easier to break up her pairing with Kaito Kid without sparking arguments. She's also an invincible beautiful girl, except she's a bit eccentric at times.
