I Guarantee Conan

Because of the protagonist's time travel, Conan is no longer the protagonist. Because Conan is not the protagonist, Conan will no longer have the protection of the protagonist's halo. Because Conan is no longer protected, Detective Conan is no longer called Detective Conan. There is no Conan behind the detective, so this book no longer exists. The world of Conan will collapse, so the protagonist must protect Conan. This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
