It will feature three brand new characters to add to the canon dramatis personae:
Also known as L mark 2 (or should that be mark 4, seeing as we have to account for Near, Mello and Matt), Ryūzaki is a world famous, top-class detective lured into the spotlight by the emergence of no less than SIX Death Notes.
Shinigami are getting very careless these days. Or bored.
However, Ryūzaki isn't merely a Wammy kid grown old enough to get chucked onto the front line. Like all the rest. He's legitimately an heir of L, bloodline, genes and all.
No, this isn't a secret love-child that we've uncovered here. It's much worse than that.
Apparently L left behind a sample of his DNA, so that he might be cloned, into a global detective, called Ryūzaki.
This new Death Note character will be played by Sōsuke Ikematsu, known to the cinema going public as Higen in The Last Samurai and Kazuhiko Shingai in MOZU.
Ryūzaki is aided and abetted in this endeavour - and no doubt given the heads up re a sudden epidemic of Death Notes - by police researcher and archivist Tsukuru Mishima.
The spiritual (as opposed to genealogical) successor to Soichiro Yagami and his crew, Tsukuru Mishima specializes in artefacts from the Kira case that went before.
Ten years previously to be precise.
Therefore the investigator is well placed to recognize the reality of each new notebook dropped by a Death God in various locations around the globe. He becomes the go to expert for all other authorities within stricken nations.
Or more likely, he does whatever Ryūzaki ends up directing him to do.
Tsukuru Mishima will be played by Masahiro Higashide. The actor's other roles include Hideo Shimada in Parasyte and Kō Mabuchi in Ao Haru's Ride.
And what's a Death Note story without a Kira? Or in this instance, a Kira worshipping cyber-terrorist and/or hacker named Yūgi Shion.
Me and popular media don't often agree upon what constitutes a 'cyber-terrorist', but this time we may be in accord.
Yūgi Shion uses his computing skills and internet presence to not only locate all fallen shinigami notebooks, but also has some role in co-ordinating events.
He may or not be the individual already announced - in a snippet from the Death Note 2016 movie trailer - as being cloned from a shard of Light Yagami DNA. Though how anyone got that is anybody's guess, particularly as they had to get through Near to reach the corpse.
Unless it was Near. In fact, where is Near in this movie plotline now?!
Oh. Movies. He's an infant maths genius just entering Wammy's House as L was killed. Not manga instigator of the Yellow Box pwning at all. He should be just about old enough to be, well, Ryūzaki by now. Because the new L isn't a ten year old either.
Back to the actual plot - Masaki Suda will be playing Yūgi Shion; an actor also known as Karma Akabane in Assassination Classroom and Kuranosuke Koibuchi in Kuragehime.
Any tremors of excitement building over this out there?
