If you take a look at this chart, you can see the relationships of the characters (which are similar to the original series). Their ages are all stated in brackets. Small yellow label indicates one who has thus far recieved a Diary.

The 40 year old man on top right-hand corner is Kurusu's counterpart. The 27 year old woman under him is possibly Minene's counterpart, as the description says "unknown woman who enters school campus". The man whose arrow is pointing at her is a detective, probably Nishijima's counterpart as he "inquires after her", although he is a diary owner... (roles switched?)

John Balks' counterpart is the man in bottom left-hand corner. His Chronos Seed Corporation issues limited edition smartphones which are Diaries. Guy next to him is Kurou, Yuki/Arata's father, who works for Chronos Seed Corporation as a developer. Somehow he recieves a Diary... Rea is the one next to him.

Guy in top left-hand corner is Rui Moriguchi, Yuki/Arata's friend, who lends him his smartphone - turns out to be a Diary. Sister next to him.

That's about it for the cast as this present stage. Other characters are as of yet unknown.

Oh, and if you can't figure out who the Yukiteru and Yuno of this series are from this chart...
