Thoughts; I've still not figured out just how I want to do these long series, My memory kinda sucks so I think I want to break them down into half way points or when the show seems to come to a nice temp stopping point.
Who is Dead: Third, Fourth, Fifth, Tenth and Twelfth.
Who's "new"....
Seventh - Ai Mikami and Marco Ikusaba - The Exchange Diaries - They report each others immediate future. At first they were using "Apprentice" Diaries but later revealed that they were true Diary users. The two of them are a couple, Both orphans that had been abandoned by their parents as children.
When attacking recently reunited Yuki and Yuno at Kousaka's house they end up stealing their diaries after Yuno is utterly beaten up by the combination of the twos attacks. Marco gives Yuki an earful for being so pathetic... hiding behind a girl.
I guess they were using the phones to gain information since they didn't just snap the things, They did see that Yuki's father was working with Eleventh and sadly ended up dead after they demanded a meeting with the father, Yuki and Yuno.
Eighth - Kamado Ueshita - I love this woman! She is so strange looking and you really just wanna hug her. She runs the orphanage named "Mothers Home" and her Diary is a Blog server of sorts. Renting out space to users they can eventually become Apprentice Diary holders. Most her kids seem to have them.
Before her death Eleventh was trying to have her Orphanage torn down, That way he could get her Blog Diary for himself. This woman should have never died but... While teaming up with Yuki and Yuno to take down Eleventh she and her kids are betrayed.
Oddly though, Eleventh saves her from death..or not so oddly he still wants to use her Diary for his plots. In the end though she dies by Yuno's hand, Trapped under fallen rocks she stabs her. :(
Eleventh - John Bacchus - It's the Mayor!! - He holds the Watcher Diary, It can see entries from other Diary Users but can't decipher if their true or not. This guy just deserved to die, He wanted to hook up Eighths blog diary to a super server and make the entire city "Apprentice" Diary users. Actually, He did hook it up but Ninth blew up part of the super computer causing not all of the city to connect.
In the end, While running from First and Ninth he locks himself in a bank vault that was once owned by Yuno's parents. Thinking Yuno wasn't the "real" Yuno he believed that noone could open the vault... he was wrong. Killed by Yuno.
Non Diary Users
Rea Amano - Yuki's mother, Very understanding mother. She is rarely at home due to her job being a video game programmer. She met Yuno in episode six and seems to very much approve of the relationship, Even so much as to show Yuno, Yukis baby pictures.
She's really not in the series much and in episode 17 she is killed by Yuki's father when she attempts to bring him to the police after he abandons his son and Yuno in the falling tower.
Kurou Amano - Yuki's father, He doesn't show up until episode 16 while Yuki is in the hospital after his encounter with Seventh. He gets a little, perverted with "Nurse Ninth" and trains along side of Yuki with the bet that if Yuki does better that he will do what Yuki wants, Which is to get back together with his mother.
Poor Naive Yuki. His father is a real shithead, He's gotten himself into major debt and is just there to destroy Yuki's cell phone. Of course he doesn't realize this will kill his son but I doubt he'd care if he did know..
Seventh becomes interested in him when they find out {through the phones} that Kurou is working with Eleventh meaning he knows who he is. Having gone with Yuno and Yuki to meet Seventh at the tower he steals the only working parachute the kids have and escapes the crumbling structure, On the ground he runs into his ex-wife and...stabs her.
Later while trying to make amends with Yuki he is stabbed/killed by Elevenths men.
Masumi Nishijima - Chief Investigator - He takes over once Fourth dies, He's not a Diary user but has a past with Ninth. He tried to arrest Ninth a while back while she was running from Third, There she got away and now they are somehow reunited.
It's not explained why but Nishijima falls in love with Ninth or maybe it can't be explained, He takes her side while she's after Eleventh and while she, Hinata and the others are going after what remains of the Server and Eleventh himself he proposes to her.
Before they can even get out of the building however, He's shot to death while protecting Ninth.
Hinata, Kousaka and Mao - Yuki's friends - They end up being killed by Yuki himself during his crazy stage. Before their deaths they helped him go against the other Diary users.
Updates -
Ninth - She ends up falling for Masumi Nishijima with whom she's had a past, Even accepts his proposal before he is killed while protecting her. She herself ends up "dying" during the siege on Elevenths building, She used the bomb that she has attached to her heart to try to open the Vaults door in which Elevnth is hiding.
Everybody's Dead. Maybe.
