I think they should be introduced differently from the other villains like have them become Jeremy's neighbors with no hype or connections to the other characters except Klaus(him suggesting Tokyo might be them nudging it). I think it would be funny if it went a Fright Night/Disturbia route and had the storyline focused on Jeremy trying to prove Shinichi and Misao are supernatural lol. I'm will laugh if we see Shinich and Misao pulling classic creepy movie scenes and Jeremy screaming "There you see does that look normal to you!!!" and people (originals included) saying "Jeremy your seeng things that aren't there." and ironically Klaus (in Tylers body) is the only other person who thinks something is up with the new kids on the block. Can you see Team Mystic Falls being that ignorant of a threat?
