Detective Conan: Randall Can't Get Motivated

The story of a gentleman in the world of Conan. He'll follow his principles without a second thought, even firing an anti-tank rocket to take down an Apache (don't ask why one is there). He'll also casually send members of a mysterious organization who like driving vintage cars flying with a C4 bomb... All right, that is very gentlemanly.

After Kaito Kid got himself into trouble, the deadly Plane Gem was activated. The timeline of Conan's world changed, and a series of bizarre, fantastical worlds merged into it.
