Have you not noticed that alot of things happen in Konquest that are impossibly non-canonicle? For instance Shujinko meeting every character with them being in at least 3 places at once?
3 Places At Once? Oh So I Guess Its Impossible For Those Characters To Travel Between The Realms. Characters Have Done It In The past. Plus Shujinko Is Getting Older As Konquest Goes On So It Might Not Be 3 Places At Once It Might Be 3 Different Time Frames. Also Not To mention Reiko Is Only In One Realm In Konquest Mode.
