So in the end, Allen left the Black Order. After all the business with Alma, he was held in a cell until a strange bishop managed to knock out all the guards in his cell. The bishop revealed himself as Apocryphos, an autonomous-type of Innocence that guards the Heart innocence and tried to absorb him. Tyki, Road and the Third Exorcists then unexpectedly saved him from Apocryphos and helped him escape the island.
As it turns out, General Cross was searching for the host of the Fourteenth for 30 years, (he looks really good for his age), before he met Allen. Which doesn't really add up considering how old Allen is. Since there's no body, I still doubt he's dead.
Man, I didn't actually think Kanda survived after the fight with Alma. His Anti-Akuma Weapon became a Crystal type just like Lenalee's. The only reason he came back to the Order was to help Allen. Allen going so far for him and Alma changed him and his opinion on Allen. Kanda actually regrets not telling Chief Komui about the signs of the Fourteenth taking over Allen in Paris, and now I wish he did. Even so, Allen is determined to not let himself be swallowed by the Fourteenth, while still acting as an Exorcist on his own and dodging Apocryphos. Walking on his own path.
Okay, I won't lie. I hate how the majority of the anime was the Alma Arc. It's not that it was boring, it's just not a lot happened. There wasn't much action overall. I also just hate how right after Allen's Innocence became so powerful that it could action destroy the Noah without killing them, this Fourteenth crap just made it's way into the plot. If Allen didn't have the Fourteenth's memories, he would be a General right now, gold coat and everything. It just seems like he just got back his Innocence and was doing so well, and then things went horrible for him. He isn't really sure where he belongs.
I also don't like how the Order was looking towards the end. The Noah and the Akuma are mass murderers, the people at the top of the Order might not be great, but the people at the front lines, the Exorcists and those who aid them, they're good people. I wish Allen would have believed in his friends.
I found out about this series in a old Shonen Jump magazine that I bought used from the local library back when they were still making them in print. There was like a slip of paper that you'd find in a dvd that showed a visual from the first season with a summary on the back. I was interested and maybe a few months later, the first two seasons showed up at the library. I just loved it, I heard there were more seasons and I was sad when I found out the last two weren't licensed. I still have it today, it features a story that had Allen and the others dealing with members of the Order turning into zombies because of Komui. It was pretty fun, and I was hoping that would have adapted, but it wasn't.
I've also started to read old interviews that Katsura Hoshino gave to try to get a sense of how the series got where it is right now.
Like this one.
All in all, D.Gray Man Hallow could have better. It should have had more episodes, I think it was wrong to adapt what I heard was 90 chapters in 12 episodes. This just makes me afraid for Muhyo and Roji's.
As for D.Gray Man itself, it's good. I think it's probably better to read the manga in this case, then watch the anime. I haven't given up on the series, and I still intend to follow it until the end.
