Disclaimer: I don't own Detective Conan, all the wonderful characters are not mine, no matter how much I would be okay with that.
I was sitting in music appreciation this morning and had this revelation: Shinichi is such a vague and almost non existent person to the children detectives. If they were to make a list of all they know about 'Shinichi-niichan'. I recommend "The perfect weekend" by magicbulletgirl for another look at the Shonen Tantei's view of Shinichi.
10 things the Shonen Tantei know about Shinichi-niichan
1. He is some vague relation to Conan-kun
2. He is Ran-neechan's boyfriend
3. He is far away and very rarely returns. He has only been home for one day since they've known Conan-kun.
4. He's a detective
5. He taught Conan-kun about being a detective
6. His house is that creepy haunted place that no one lives in, the one where a demon ate a boy, supposedly, next to Dr. Agasa's house.
7. Ai knows him
8. Dr. Agasa knows him
9. Mouri-san doesn't like him
10. He only comes home when Conan-kun is away visiting his parents, so the latter doesn't ever see him, but they must talk on the phone a lot
