Detective Conan: A Collision of Black and White

First, a disclaimer: I'm not very good at writing, but please don't attack me for it. This is a crossover fanfic. <So far, it only includes Detective Conan and Bungo Stray Dogs.>

2. There is no female lead. Feel free to ship the protagonist with himself, or pair him with another man.

3. The male lead has many identities and plays different roles on both the good and bad sides.

4. He has a chronic illness, so there may be some inconsistencies.

5. My dialogue doesn't sound very natural, so please bear with me.

6. The five-member team and other important characters on the good side will be saved.

7. The protagonist's loyalties will shift as the story calls for it. He may stay balanced between the good and bad sides, or lean toward one of them.

Boss: My child, perhaps you're ready to take my place.

Vermouth: Sweetheart.

Gin: A madman and a genius all in one.

Judy: He's very meticulous, but at least he's on our side.

Shuichi Akai: He's a lot like that person.

Conan: Ling-ge is always so...

The five-member team: Poor little “kitty.”

Ai: He's an outside member, and a test subject, too. Poor thing. It must hurt a lot most of the time.

Everyone: (Crying.)

Suzuki Tsukiyo: Are you all cosplaying or something?!
